SPECIFICATIONS. Though the Decathlon went out of production within a decade of its introduction, this was not due to any fault in the design, but rather to the slump in general aviation in the United States at the end of the 1970s and the beginning of the 1980s. Or is the extra drag just neglected in the calculation? No one expects an air cooled 160hp with a carb. Early Citabrias were fitted with a steel tube main gear which uses an oleo strut for shock absorption. The new Cessna 177 Cardinal with its cantilever, laminar-flow wing offering terrific visibility is a doll to fly, a step above its trusty-yet-pedestrian predecessor. THE GLIDE TIME IS SHORTENED. Aircraft weight, air density (e.g. Designed for flight training, utility and personal use, it is capable of sustaining aerobatic stresses from +5g to -2g. American Champion Aircraft Corporation acquired the Citabria, Decathlon, and Scout designs in 1989 and returned the 7ECA, 7GCAA, and 7GCBC models to production over a period of years. Best angle is listed as 70. Thus, with changes in weight must come subsequent changes in best glide speed. If you wish to make some sort of pursuasive argument then post up some horrid examples of glide ratios for twins. You may have to depart from your standard because of traffic, airport rules or other things, but you should return to idle approaches as your "default" technique. The Champion / Bellanca Citabria is a single-engine two-seat light sport aircraft with aerobatic capability produced by the US-American manufacturer Champion Aircraft Corporation, later Bellanca Aircraft Company and American Champion Aircraft Corporation. (You must log in or sign up to reply here. The glide ratio varies with air speed, but there is a maximum value which is frequently quoted. Daher Kodiak 100 Specifications. 14:1 means 14 km of distance per 1 km of altitude. Cruise Speed/Endurance with45 MinReserve @ 75% Power: 127mph/ 2.8 hrs, Fuel Consumption(55% to 75% Power, per Lycoming Data): 7.3 to 10gph. We purchased it from Doug Cline in 2019. rather than 7.01 or 5.01 ? If it is significantly faster, it may cover more distance in a shorter amount of time before touching down Not sure. That model was abandoned by aerobatic enthusiasts in favor of the Champion Decathlon 8KCAB because of its better inverted flight performance. 5. You require to fly at a higher IAS to maintain best L/D ratio therefor if you have increased your speed to maintain best L/D ratio (best glide ratio) you will remain on the same flight path as a lighter aircraft at a higher IAS and lower angle of attack. Find N57682 1973 BELLANCA CITABRIA 7GCBC on Aircraft.com. glide path is not the same as attitude / angle of attack (AoA). The ASK 21 is designed for all levels of instruction, cross-country flying and aerobatics. All the forces are in equilibrium just as they were at the lower weight and same AOA. Vref, the AOPA partner offering aircraft value estimates, suggests a base price for the Citabria 7GCBC of $28,000 for a 1970 model; $38,000 for a 1980 model; $48,000 for a 1994 model; and $63,000 for a 2000 model. Per the C180 owner's manual, sea level best rate is listed as 87 - 90 mph. On acquiring the design, Bellanca gave this model the name Citabria "Standard" and began using the 115 horsepower (86kW) Lycoming O-235-K2C engine. The Glide Ratio is the ratio of distance forward to distance downwards when a glider is flown at a constant speed in still air. NO OTHER CHANGES. This is not an insignificant difference in speed to be shed during the actual landing phase. American Champion's 7GCBC, reintroduced in 1994 as the Citabria "Explorer," is similar to earlier versions, with the exception of the metal-spar wings and the use of the Lycoming O-320-B2B of 160 horsepower (120kW); the most recent significant design change has been the switch to aluminum main gear legs in 2004. . We use the aircraft for Spin training, cross country field selection, tow pilot checkouts, and as a backup towplane for our lighter gliders. The added weight requires more lift. The DA40 can do about 11:1 at lower altitudes, and gets better the higher you go (true of any airplane, due to higher TAS at altitude maintaining Vg IAS). I do engine off landing all the time.. One of the major developments of the 8KCAB Decathlon over the 7KCAB Citabria is the Decathlon's wing, which employs a semi-symmetrical airfoil, as opposed to the Citabria's flat-bottomed airfoil. Recommended Engine TBO: 2000 hours. To BART, Jan 10, 2015: A typical American training glider has a glide ratio of about 24:1. By continuing to use this website, you are agreeing to our Cookie Policy. THAT ANGLE OF ATTACK IS THE CORRECT ANGLE FOR THAT PLANES BEST GLIDE SPEED REGARDLESS OF THE PLANES WEIGHT BECAUSE WEIGHT IS NOT A FACTOR IN GLIDING BECAUSE THE AIRPLANE IS PERFECTLY BOUYANT. for approved maneuvers in the acrobatic category. It's easier from the back seat, but that's not where you solo this aircraft. Someone on the internet gave a Vbg of 135MPH for a total glide time of 60 * (6/135) = 2 minutes 40 . It's not a fixed number and the 50:1 ratio will only be achieved at one speed. The plane is now EXACTLY as buoyant as it was before. The Citabria POH/AFM is a piece of junk, isn't it? Why should I think its not on the exact same glidepath now? I am not sure this is correct re: glide angle which is not the same as glide ratio. And how do I judge that angle ? Description: The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. Both at the same time? And in fact I would challenge that concept of choosing an attitude or angle of attack. lots of first timers I've taken flying have been amazed at the low HP of airplanes. Its name spelled backwards is, "airbatic". Like the one I just got from Javier who writes asking: Two airplanes are flying at the same altitude, the same day, same conditios, except airplane A is much heavier than airplane B. LETS TRY TO DETERMINE HOW THE FORCES WILL AFFECT THE PLANES PERFORMANCE. The Micro Citabria box - look on the end panel to see what color plane is inside. The C172S will descend at about 760 feet per minute. The heavier? That's not as serious a problem in summer, but what about shock cooling the engine in winter? N3822A, Glider: SchweizerSGS 2-33ATail #: Glide ratio is the distance a glider (aircraft without an engine or the engine switched off) covers for each unit of altitude lost while descending - e.g. Production at Bellanca ended in 1980 and the company's assets were liquidated in 1982. The electrical system is 12 volts, direct current, using the airframe as a negative ground. They also are are not equal if there is horizontal or vertical wind. If you have a GPS just hold an airspeed, throttle back, decend a fixed amount and see how far you went. when I had my mac attack that is what I did and it seem to work.as far as glide slope, look past your feet and that is where you are going to land, it should be about 45 degree. The Citabria traces its lineage back to the Champ. Bellanca Citabria 7GCBC. Demonstrated Crosswind Component: 17 kts. To Mark, JAN 10, 2013: Both aircraft will cover the same distance but the lighter one will take a longer time to do so. Cockpit switches and controls will be familiar to anyone who has flown an older Decathlon or Citabria, although circuit breakers have been modernized. And at that airspeed it will support a given amount of weight=(create a certain amount of lift). The strut-braced wings of the Decathlon are, like the fuselage and tail surfaces, fabric covered, using aluminum ribs. Airplanes fly on excess power, not grace, not engineering. The cross-section of the metal fuselage truss is triangular, a design feature which can be traced back to the earliest Aeronca C-2 design of the late 1920s. Our FLSC Pegasus is a B model that has a carbon fiber main spar, I'd bet that the glide ratio of a twin with both engines out and neither prop feathered would be genuinely awful. Rolls are okay, though and loops. You have to explain that a little better than that. So Joe, Jim and Paul are correct but they have not told us how they determine Table of Contents. The main gear legs of most Citabrias are made of spring steel, though American Champion began to use aluminum gear legs in 2004. (Jun. HERES WHERE MY THINKING MAY GET SCREWED UP. The last two positions, 27 degrees and 35 degrees, are a tough pull. The POH only gives the best glide distance in the clean condition. What, if any, specialty instruments are used for professional glide ratio testing (such as a manufacturer developing a new model)? [2] It was never put into production at Champion nor by Bellanca which acquired the company and designs only a short time later. Champion 7ECA Citabria - 1-2280 - CABLE ASSEMBLY - RUDDER PEDAL. The angle to the left wing from the pilot eyes is around 5.4 degrees. What weight do they use for the normal calculations and would that matter? If two aircraft have the same L/D ratio but different weights and start a glide from the same altitude, the heavier aircraft gliding at a higher airspeed will arrive at the same touchdown point in a shorter time. Bellanca continued production of the 7GCBC, calling it the Citabria "C" Package (a designation apparently begun by Champion). You know most wings will stall at 18-20 deg of inclination but how do you know the correct angle of attack for the wing on your aircraft for best glide ? I'll bet there are some out there. The airplane is powered by a horizontally opposed, four cylinder, direct drive, normally aspirated, air cooled, carburetor equipped engine. I also know there is a direct relationship between AOA and airspeed. Let me know what you think. (You must log in or sign up to reply here. The 1-26 is the most numerous sailplane found in the US. Demonstrated Crosswind Component: 17kts. WHAT HAPPENS IF WE INCREASE THE WEIGHT THE VERY MOMENT THE GLIDE STARTS? 4 products. And, on a side note, do any of you happen to know the glide ratio for a 7GCAA? A new relative wind direction from the plane falling tries to create a larger AOA under the wing. Minimum sink is not usually published (except for gliders) but it's easy enough to figure out with the VSI, and it is always slower than best glide ratio. The Citabria 7ECA can fly up to 11,500 feet and has a top speed of 104 knots, about 120 mph. Login . Citabrias were also popular as trainersbecause of their conventional gear and their aerobatic capabilitiesand as personal aircraft. Description: The Schweizer SGS 1-26 is a United States One-Design, single-seat, mid-wing glider built by Schweizer Aircraft of Elmira, New York. View photos, ownership, registration history, and more. tan -1 (1/14) or tan -1 (0.714) or 4.086 degrees. Compare. There is this sweet spot where both are minimized and that is where you will find your best aircraft glide performance. Most think this is blasphemy, so take it with a grain of salt: In that period, only one Citabria model was builta 7GCBC marketed as "Citabria 150S." "It reduces a lot of problems," Mehlhaff, Jr., said. Increased wing rigidity is to blame for the float, Mehlhaff, Jr., said. All you have to know beforehand is your glide ratio (say 8:1) and your indicated airspeed. Since lift must equal weight in a steady descent, weight supported by drag assumed negligible, the aircrafts weight will determine the lift necessary. Welcome Guest. A-759. How much does a Citabria cost? Minimum sink is always slower than best glide, because it's the point on the power required curve where the least amount of power is required. Best glide ratio is the most optimal - the highest - one. Also, there is no thrust to move the aircraft. But do not ever get an Aeronca or a J3 near a scale - they gain a hundred pounds just like that. Really ? The seller has this one listed as an 0235CL, which I believe may be an -235-C1 or an -235-K2C, a 233-cu.in. The only thing that has changed is the rate at which the plane is proceeding along the glide path. Description: Our Club purchased this glider simulator in 2019 for our students from Russell Holtz. But I am not sure of that. Do it again for different airspeeds. An aircraft has a single best glide speed for a given configuration. Does an SR 22 require any additional rating or endorsement? Gliding Distance is given by. The SGS 1-26 enjoyed a very long production run from its first flight in 1954 until 1979, when production was ended. It is applicable to Serial Numbers 1240-98 and up. Bank Angle Fuel Capacity: 36 gal. Do you disagree? The lighter? When imported it was registered in the USA - as an A model. Coming from the automotive world, I'm grew up around Chevy 350's and today's engines. Ceiling: 17,000. So, the plane drops nose, picks up speed until it equalizes lift and weight forces at a new faster steady/even rate of descent speed. All of the variants are discussed in more detail below. Champion and Bellanca built the Decathlon with several Lycoming IO-320 engine variants, all of 150 horsepower (110kW), and with the choice of a fixed-pitch or constant speed propeller. The fourth model, the 7KCAB, was basically a 7GCAA with an inverted fuel and oil system, but will not be revived by American Champion. Your Cessna needs 120HP (75%) to maintain it's rated cruise speed. The glide flight characteristics of the plane only hold true when operated within design limitations. This can be the difference between going home ! Its the added speed that balances the extra drag, Both instructor Davis and owner Davis cautioned prior to the flight that the airplane likes to float on landing. Left & Right Wing LED Lighting (with Flood & Wig-Wig). Bellanca Citabria 7ECA Technical Specifications Exterior Exterior Height: 7 ft 7 in Wing Span: 33 ft 6 in Length: 22 ft 1 in Interior Cabin Height: 3 ft 11 In Cabin Width: 2 ft 6 In Cabin Length: 8 ft 10 In Occupancy Crew: 1 Passengers: 2 Operating Weights Max T/O Weight: 1650 Lb Empty Weight: 1060 Lb Fuel Capacity: 35 gal Lb Payload Useful: 590 Lb Decathlons and Super Decathlons remain popular as aerobatic trainers, as beginning and intermediate aerobatic aircraft, and as personal aircraft. Your glide ratio needs to be determined empirically. Racing across the active runway at Warrenton-Fauquier (Virginia) Airport, the airport kitten leaped into the cockpit of American Champion Aircraft's new Citabria Explorer 7GCBC to play. The Aeronca Model 7 Champion, more commonly known as the Champ, is a single-engine, two-seat, fixed conventional gear airplane. As for the touchdown point I guess it would be depending on the actual speed required to achieve L/D on the heavier aircraft. Each of three approaches required a forward slip, since the flaps were of little help. Champion's first Citabria flew as a prototype in May 1964. AN6-25 BOLT 1-2550 BUSHING AN310-6 NUT AN945-6P WASHER. GlobalAir.com is your partner in connecting you with relevant information and resources. Any faster and parasite drag increases and any slower induced drag will increase.. ? 7ECA, Citabria Standard, Citabria Aurora. C) remain the same A typical commercial airliner will glide at a ratio of about 3:1. Lighter Total system is now 3 lbs. Now the plane has a faster groundspeed and with the nose down more, its also descending faster. This glider was rebuilt by Chuck Zabinski and Jake Smith. I used the following estimates. L=cL(1/2 x Rho x v2) S. Higher weight requires higher lift. Brian; Not airspeed Joe, Angle of Attack. Usable) Oil Capacity: 8 quarts Baggage Capacity: 100 lbs. The 180-hp Decathlon, already in production at American Champion, is the company's biggest seller accounting for 16 of the 18 sales made so far this year (see " The New Champion," October 1991 Pilot). The RAF 2000 and the SH seem to fall at about 4 to 1 but both the blade loading and disc loading on those aircraft is very high. I just read elsewhere that altitude / air density does not effect glide ratio but it seems your explanation says it does effect glide ratio. Why? Fuel Burn at 75% power in standard conditions per hour. Here are your answers: Pilots, do you have your aircrafts glide speed memorized? TO OUR GLIDE RATIO (AND ITS RESULTANT GLIDE SLOPE)? Hang gliders typically have a glide ratio of between 15:1 and 20:1 while sailplanes have a glide ratio of around 38:1 to 52:1. Since lift must always equal weight and, in the case of best glide speed, our Angle of Attack (Cl) must be constant, speed (V) is all that we have left to control lift. So if I were at 10000 feet and lost all my engines, I could expect to glide about 30 miles. Especially when the angle is so slight. In comparison, a Boeing 747 has a 15:1 glide ratio. 2. . 45 and 45 is what I was told. Remains of the plane were found 13 months later near the town of Mammoth Lakes, California, just south of the original search area. The major difference was in the engine, which in the 7GCAA was a Lycoming O-320-A2B of 150 horsepower (110kW). Custom Doggy Mat. Discussion in 'Flight Following' started by Morne, Dec 21, 2011. average spam cans seem to be right around 8 or 9:1. I don't know of a list. One glide I did from 7500' down to the surface at ~800 MSL resulted in an 11.54 glide ratio. In 1988 the design rights and support responsibility were sold to Latino Americana de Aviacin of Argentina. Though variants of the design, and other better-suited designs have largely taken over the Citabria's utility roles, Citabrias remain popular as trainers, glider towplanes, and for personal use. The wood winged 7GCBC weight go up to 1800lbs on edo 2000 floats. Yippee! Glide ratio usually varies little with vehicle load; a heavier vehicle glides faster, but nearly maintains its glide ratio. So based on the information above. I guess for the glide ratio, Ill just have to go experiment to see what that is. The following formula is used: = S / H where: = Glide Ratio S = distance of forward travel The model 7ECA Citabria entered production at Champion in 1964. hotrod180 offline. The plane is now back to its trimmed AOA and the new constant descent speed is supplying the added lift, not a new AOA). In this example, the glide ratio provided in the POH comes out . Our glider has blocks that can be rotated in front of the rudder pedals to accommodate shorter legged people. An "Ultimate Adventure" version, with a Superior Vantage O-360-A3A2 engine of 180 horsepower (130kW) and a composite propeller, is also produced by American Champion. When introduced, it featured wood-spar wings and oleo-shock main gear. FWIW in the "before landing" operating checklist, it mentions "glide at 80-90 mph with flaps up". lighter. American Champion Aircraft Corporation acquired the Decathlon design, along with the 8GCBC Scout and the group of Citabria and Champ variants, in 1990, bringing the Super Decathlon version back into production that same year. The 1979 book I have has performance charts, but my 2001 book doesn't. Go figure. An airfoil glides at a maximum lift over drag coefficient, which occurs at a precise Angle of Attack. On this Wikipedia the language links are at the top of the page across from the article title. Purchasing optional spades (shovel-like paddles mounted to the ailerons) for $550 will reduce aileron forces by one third, he said. Glide ratio is defined as the ratio between altitude when it start gliding (Y-axis) to the distance it can reach until the altitude reach zero (X-axis), as shown in the picture 2. The prototype had an open cockpit for a single pilot, but the design allowed for conversion to a two seat layout. What gives? This frees you to make the decisions and troubleshoot. In 1970, Champion was acquired by Bellanca Aircraft Corporation, which continued production of all of the Champion-designed variants. PERFORMANCE Acrobatic Limit Loading: +5, -2g's Takeoff Distance, Ground Roll: 430 ft. Takeoff Distance Over 50-ft Obstacle: 895 ft. Some will find it easier to use a different calculation. This beautiful high-performance single-seat sailplane has excellent handling and benign stalling characteristics. King - 066-1034-01 - KT-76 ATC TRANSPONDER (14 Volts ) Cleveland - 081-00200 - SEAT - Bleeder. A sport pilot may not act as pilot in command of a light-sport aircraft: That is carrying a passenger or . It is good to know what your "best" glide ratio is, such as most single engine training airplanes are in the 9:1 glide ratio. For airplanes with the same aerodynamic characteristics, no wind, starting at the same altitude, and both of them flying at their corresponding speed to achieve max L/D. Ours was built in 1984 and purchased from the Wings of Eagles Museum. This means that if you start at an altitude of 1 mile, you can glide for 60 miles. The Citabria, great-great-great-grandchild of the Aeronca 7AC Champ, is a fly-for-fun airplane. N7519F, Tow: PiperPA-25-235 PawneeTail #: 1111, Glider: CentrairPegasus 101BTail #: Data from Jane's All the World's Aircraft 196970[2], Aircraft of comparable role, configuration, and era. American Champion has been using aluminum spars in the aircraft it has produced and has made the aluminum-spar wings available for retrofit installation on older aircraft. Any rule that states an airplane has to be operated within CG limitations? Boldmethod. Vy in your airplane is 69 mph. Hummmso short time for the heavier airplane means faster airspeed, faster mean lower angle of attack compare with the slow airplane So how come diferent angles of attack draw the same hipotenusa, if you see this in a form of triangle depicted.? On the aircraft I fly, the 744, at high gross weights, the ratio approaches almost 4:1, the aircraft doesn't want to come down at all. The American Champion 8KCAB Decathlon and Super Decathlon are two-seat fixed conventional gear light airplanes designed for flight training and personal use and capable of sustaining aerobatic stresses between +6g and 5g. The large wing area gives good low-speed handling characteristics, docile stalling characteristics, a excellent climb. Every once in a while I get a question on askacfi.com that Im pretty sure is a homework question but I still dont mind answering it. You can see the image damage at the end of the video. Pretty impressive. while the glide angle can change but glide ratio will stay the same. Wing aspect ratio: 6.72; Length overall: 22 ft 8 in (6.91 m) Height overall: 7 ft 0 in (2.13 . My [flying club's] M20J is about 13:1 a 172 is about 9:1. Glide ratio: 23-1 : Max G: Tow: American Champion Citabria 7GCAA Sn#:2 Tail #: N7519F Description: The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. The Kodiak is a true STOL (Short Take Off and Landing) aircraft powered up front by a PT6A-34 producing 750 shp allowing the Kodiak to get off the ground in just under 1,000 feet . Do you have the glide ratio in your book? N234WE, Tow: American ChampionCitabria 7GCAA Sn#:2Tail #: The trim control, same as that used on earlier Citabrias and Decathlons, is a sliding knob, much like the throttle, that is fast and simple to operate. Locate a Dealer. Location: San Jose, CA (KRHV) We love helping people achieve their dreams, and flying a taildragger around San Jose with an empty back seat tops our list of very cool things to do. Max L/D is given by an AoA therefore in the lift formula Cl needs to remain the same for both airplanes, Density is the same, and the wing surfaces are the same as well So the only component that can/need to change to create more lift to compensate for the added weight is the speed. Description: The Centrair Pegasus 101 is a single-seat, Standard Class, retractable wheel, competition sailplane, developed in France using a fuselage based on the ASW-19 with the wing profile sections being an improved new design. Introduced in 1964, the 7ECA was the first version of the design and utilized the Continental O-200-A engine of 100 horsepower (75kW). It was substantially similar to the 7GCAA of the same year, with a Lycoming O-320-A2B engine of 150 horsepower (110kW), wood-spar wings, and spring steel main gear legs. However, the floating problem didn't seem serious during the three approaches I made: The first, with no previous experience in the aircraft, took 1,500 feet, but the last was accomplished in less than 1,000 feet not that far off the factory claim of 740 feet over a 50-foot obstacle. The Decathlon design passed through the hands of a number of companies through the 1980s, including a Champion Aircraft Company which was no relation to the Champion Aircraft of the 1960s, but no Decathlons were built in that period. Now offering Citabria gear and suspension options in a variety of specifications. Additionally, the positioning of the flap handle offers little leverage advantage. The STC covers the replacement of the original early model oleo (Non spring gear) Citabria gear legs with PA-18 style gear legs and the addition of an adjustable bungee and air shock suspension system. It may not display this or other websites correctly. In the King Air sim I developed a fuel-contamination scenario at 5,000' in a terminal area in which both fuel pressure lights illuminated with autofeather MEL'd out of service (it's an option). Bellanca built over 600 of the 8KCAB design before production of the aircraft was interrupted when the company's assets were liquidated in 1981. https://en.wikipedia.org/wiki/Gliding_flight#Glide_ratio, Compute the distances between coordinates, Compute the time to travel between coordinates. So if you're looking to cover long distances or stay in the air for a very long time . Aircraft Page 6-Engine Out Glide Distance? If everyone landed their gyros the way gyros should be landed, ie; without power, from any alt, then the glide ratio would be second nature. 8-10:1. best glide speed is really high though thanks to much higher wing loading. In other words, the Angle of Attack for best glide will not change. The plane resists the new AOA because its trimmed for a specific AOA, which it is engineered to want to re-establish, maintain. If the C-172 has an L/D of 9.5. To take advantage of the new light-sport aircraft category, the Champion was returned to production in 2007. should i maintain the same speed or should i increase my airspeed by increasing dive angle to get 1000 ft .min ROD. 1973 & On, Bellanca Champion Citabria 7ECA, 7GCAA, 7GCBC & 7KCAB Service Manual Original . SAVE Last Update: 02/24/2023. The 7GCAA and 7GCBC variants, added in 1965, were joined by the 7KCAB in 1968. a pretty decent policy in airplanes is that if you can see it over the nose there is good odds you can't make it there. N7409Z SN#:25-3375, Copyright 2015-2023 Finger Lakes Soaring Club. Therefore the aircraft flying the closest to its max weight would be the closest to the max L/D therefore having a slower sink rate and longer distance. With no other changes the plane starts too fall. . Try this Aviation Glide Calculator. The glide ratio is based only on the relationship of the aerodynamic forces acting on the aircraft. The 7GCBC Citabria was used as an observation aircraft by the Turkish Army. [2] He took off from an airstrip at William Barron Hilton's Flying-M Ranch, about 70 miles (110km) southeast of Reno, Nevada. A C172 w 9.5/1 glide ratio (L/D) has a 6.01 deg. In addition, the carburetor was replaced with a fuel injection system, and a Christen Industries inverted oil system was fitted to the engine. Mark, not exactly. American Champion expects to begin building the 7GCAA in a year, but with a 160-hp engine. One of these aircraft is displayed at the Rahmi M Ko Museum in Istanbul. This speed is important as it represents the bottom of the drag curve. :) keep up the good job. It is also certified for aerobatic flight. Bellanca continued production of the 7GCAA as the Citabria "A" Package (a designation apparently begun by Champion), but with no significant design changes. ). PN: 1-2550 Alt_PN: AN6-25. Stepping into the Cardinal is more like sliding into a sedan than climbing into a pickup. 1. whether the flaps are deployed, the landing gear is down etc. Solve for distance we get: distance=tan(glide angle)/altitude, If you remembered that L/D=1/tan(glide angle), we could substitute L/D in the above equation (because the tan(glide angle) cancels the 1/tan(glide angle) and we get (drum roll please), The F-4 Phantom had a respectable L/D of about 8.7. First and foremost, of course, is American Champion. Wow! This should be a indicated airspeed you should try and maintain the second your engine quits or starts sputtering. Older Citabria 7GCBC aircraft produced in the 1960s and 1970s had wood spars that are prone to cracking. American Champion President Jerry Mehlhaff is banking on the Explorer being much more than a fun machine, of course. Chris Prev 1 2 3 FirstPrev 3 of 3 Go to page Go American Champion Citabria 7ECA Technical Specifications Exterior Exterior Height: 7 ft 7 in Wing Span: 33 ft 6 in Length: 22 ft 1 in Interior Cabin Height: 3 ft 11 In Cabin Width: 2 ft 6 In Cabin Length: 8 ft 10 In Occupancy Crew: 1 Passengers: 2 Operating Weights Max T/O Weight: 1750 Lb Empty Weight: 1120 Lb Fuel Capacity: 35 Lb In the glide, the aeroplane's angle of descent is about 6 degrees - about twice as steep as a normal visual glide path. Champion introduced the 7KCAB in 1968. THE TOUCHDOWN POINT IS UNCHANGED However if you fly both airplanes, not at their respective L/D, but at the same fixed speed (as it is suggested in most POH, there is a best glide speed) than the maths are different. Available in several versions, with varying powerplants and equipment, the Citabria and its stablemate, the Decathlon, have a great deal to recommend them to the recreational flyer. Takeoff Distance Over 50-ft Obstacle: 895 ft. Both of them start a power off descent at the same time at the same position. Cars only need 20-40 HP to maintain highway speeds. So what does all this gibberish mean, right? For a better experience, please enable JavaScript in your browser before proceeding.
