. The lighter? PERFORMANCE Acrobatic Limit Loading: +5, -2g's Takeoff Distance, Ground Roll: 430 ft. Takeoff Distance Over 50-ft Obstacle: 895 ft. 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. Bellanca continued production of the 7KCAB as the Citabria "B" Package (a designation apparently begun by Champion). Posts: 9992. We use cookies to help you get the best experience when using our website. Citabria 7ECA. It uses the CONDOR Soaring Software Program and is the same simulator used at the USAF Academy. 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. N574KS, Glider: GrobG 102 Astir CSTail #: The main gear legs of most Citabrias are made of spring steel, though American Champion began to use aluminum gear legs in 2004. At a critical point angle of attack, the aircraft can maintain altitude only by increasing power and is said to be behind the power curve. This page was last edited on 4 November 2022, at 14:52. All of these changes were made in order to allow for extended inverted flight, a mode not possible in the earlier models. Further practice would reduce the landing distance still further. 1973 & On, Bellanca Champion Citabria 7ECA, 7GCAA, 7GCBC & 7KCAB Service Manual Original . - MOUNT ENGINE SET OF 4. $85,500 Reg# N8552V TT: 2408; Performance Specs. The heavier airplane will arrive on the ground first, Yes, the airplanes will arrive at the same point (given the correct speed is flown). GlobalAir.com is your partner in connecting you with relevant information and resources. Why should I think its not on the exact same glidepath now? Higher is better. Citabria "A" package The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered The model 7ECA Citabria entered production at Champion in 1964. To take advantage of the new light-sport aircraft category, the Champion was returned to production in 2007. 2023 Ask a Flight Instructor All right reserved. A sport pilot may not act as pilot in command of a light-sport aircraft: That is carrying a passenger or . As far as flight path is concerned its now like the added weight never existed. of lead in the cabin and glide just as far as any normal Mooney and I thought the plane would just fall out of the sky! 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. In comparison, a Boeing 747 has a 15:1 glide ratio. 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. A sport pilot must pay at least half the operating expenses of the flight. Holy Smokes thats a good question! I would like to know the actual glide ratio of my airplane at several combinations of configuration and airspeed. Airspeed-65 MPH recommended (60 MPH minimum) 2. 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. RV General Discussion/News Usable) Oil Capacity: 8 quarts Baggage Capacity: 100 lbs. 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. Both aircraft will cover the same distance but the lighter one will take a longer time to do so. The Glide Ratio calculator computes the glide ratio based on the change in forward distance and the change in altitude. Like the Champ, the Citabria features tandem seating. Dec 19 2022. Solo Date: November 19, 2022. Description: Our Club purchased this glider simulator in 2019 for our students from Russell Holtz. 2. Increased wing rigidity is to blame for the float, Mehlhaff, Jr., said. 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. How far they go forward versus how much they drop is the glide ratio. Login . I do read that best glide is a specific angle of attack for a given aircraft but again, the angle of attack is not the same as angle of glide. THE GLIDE TIME IS SHORTENED. The Mach 0.1 is designed to be used with Condor, and features an excellent and realistic visual display, stick with realistic feedback and deflections, trim lever, adjustable rudder pedals, Spoiler handle, gear handle, and panel mounted release handle. Come on Paul. It is also certified for aerobatic flight. Champion 7ECA Citabria - 1 . Eventually, the Citabria line expanded to four models. The following formula is used: = S / H where: = Glide Ratio S = distance of forward travel It is still being produced. Assume: XXXX lbs, alt.= 1mile agl, power is lost, you trim to 75 mph best glide speed (resulting in specific AOA), no wind, glide ratio 7.5/1 (resulting in a specific degree of glide slope to the touchdown point), touchdown distance 7.5 miles, glide time 6 minutes. 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. The 7GCAA was basically the same as the 7ECA, but with a 150-hp engine. I do most every landing with engine idle, so I obviously know the drill. Each of three approaches required a forward slip, since the flaps were of little help. Can you or anyone judge 6.01 deg glide path (not angle of attack) Useful Load: 550 lbs. Vy in your airplane is 69 mph. 3, 2005.) And how do I judge that angle ? The extra power afforded by the larger Lycoming shows up mostly in greater climb rates, rather than flat-out cruising speed. The wings of Champion and Bellanca Decathlons were built with wooden spars. People should practice engine-outs by landing with idle power whenever possible. (just kidding). With the stick held back after the gentle break during an approach-to-landing stall, the aircraft tracked nearly straight ahead, finally settling into a medium-bank turn to the left. To BART, Jan 10, 2015: Coming from the automotive world, I'm grew up around Chevy 350's and today's engines. 3. Obstacle: 850 ft. VNO(Maximum Structural Cruising): 120mph. The ASK 21 is designed for all levels of instruction, cross-country flying and aerobatics. It's not a fixed number and the 50:1 ratio will only be achieved at one speed. 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. A) decrease The only effect weight has is to vary the time the aircraft will glide for. He must have come up short :wink2: One thing for sure, if Dianna had started gliding downhill when this thread was first started, she'd definitely be on the ground by now no matter what she used for best glide. I am all about learning so help me out here. Does an SR 22 require any additional rating or endorsement? The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. Do you disagree? Thanks, hi i just wanted to ask that while practicing a flameout landing.. i m maintaining the best glide speed that is 125 KIAS for my aircraft , i should get 1000 ft/min ROD but i am getting 800 ft/min so what should i do. The Decathlon entered production in the United States in 1970 as a more powerful and stronger complement to the American Champion Citabria line of aircraft. Champion 7ECA Citabria - BUSHING. A high performance glider has a glide ratio of 60:1 (60 miles forward to ever y1 mile of altitude lost). Perhaps I am to understand that angle of attack stays the same in best glide, Reduce power but maintain altitude, reduce power some more, maintain altitude. The Citabria designs 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. glide path is not the same as attitude / angle of attack (AoA). Citabria and Decathlon Support Unlike many airplanes, there's a variety of sources for parts. A modern German counterpart about 33:1. Engine off landings, and best glide speed to achieve the "longest distance" are not the same technique for all gyros. Merry Christmas everyone! Demonstrated Crosswind Component: 17 kts. Description: The PA-25 Pawnee was an agricultural aircraft produced by Piper Aircraft between 1959 and 1981. Because the AOA remained unchanged, this once again perfectly balanced plane will remain on its same glidepath and arrive at the same touchdown point. The engine was replaced with a Lycoming IO-320-E2A of 150 horsepower (110kW), while a header tank of 1.5 gallonslocated beneath the instrument panelwas added to the fuel system. How do you determine the best engine off glide ratio in a gyro? American Champion has been using aluminum spars in the aircraft it has produced and has, as well, made the aluminum-spar wings available for retrofit installation on older aircraft. Description: The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. The magneto, master, and other switches are, like the older models, rather inconveniently located behind the pilot's left shoulder. Since its reintroduction, the Super Decathlon has sold steadily. Department of Transportation. Its name spelled backwards is, "airbatic". Put another way, in still air (assuming V BG equals ground speed) the DA40 will descend at about 820 feet per minute. Instructor Davis said the aircraft requires a long, flat approach, but that was inhibited somewhat at Warrenton by trees off the approach end. Designed for flight training, utility and personal use, it is capable of sustaining aerobatic stresses from +5g to -2 g. Its name spelled backwards, "airbatic", reflects this. 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. Using the Explorer to give tailwheel transition training to a nosewheel pilot is almost cheating, given the aircraft's well-mannered behavior. WHAT WILL THESE CHANGES DO TO OUR TOUCHDOWN POINT? Sorry, JavaScript must be enabled.Change your browser options, then try again. Variations in aircraft weight do not affect the glide angle . The Champion two seat aircraft was powered by a 108hp Continental fourcylinder engine. that specific attitude. Do you have the glide ratio in your book? The pilot did an awesome job, cool as a cucumber. Ours was built in 1984 and purchased from the Wings of Eagles Museum. Custom Doggy Mat. . This Bellanca Citabria is ready for an afternoon of fun! Is all that possible ? Your Cessna needs 120HP (75%) to maintain it's rated cruise speed. One of these aircraft is displayed at the Rahmi M Ko Museum in Istanbul. 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. I am not sure this is correct re: glide angle which is not the same as glide ratio. This frees you to make the decisions and troubleshoot. JetPhotos.com is the biggest database of aviation photographs with over 5 million screened photos online! So if I were at 10000 feet and lost all my engines, I could expect to glide about 30 miles. THE ONLY CHANGE THAT OCCURS IS IT WILL GET THERE QUICKER. All bets are off when the wing stalls. The 7GCBC Citabria was used as an observation aircraft by the Turkish Army. gyro's don't glide far. The engine is a Lycoming Model O-235-K2C and is rated at 118 horsepower. What, if any, specialty instruments are used for professional glide ratio testing (such as a manufacturer developing a new model)? The prototype had an open cockpit for a single pilot, but the design allowed for conversion to a two seat layout. Maximum speed: 162 mph. :) keep up the good job. (Jun. 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. 13:1 with the prop stalled, MAYBE. Champion's first Citabria flew as a prototype in May 1964. Production at Bellanca ended in 1980 and the company's assets were liquidated in 1982. An extremely expensive, highly competitive glider today can have a 60:1 glide ratio. 1974 AMERICAN CHAMPION 7-KCAB CITABRIA New Item. Glider: SchleicherASK 21Tail #: 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. Official Burn Certificates. IF IM WRONG SOMEBODY OUT THERE PLEASE SET ME STRAIGHT. Bellanca Citabria 7GCBC. Using trigonometry we get an angle of about 4 degrees below the horizon. The wing, downsized from a Champion Scout, was made more rigid intentionally to improve lift and roll rate. The fuselage and tail surfaces are constructed of welded metal tubing. And by the way, there are times you are not interested in longest glide to reach a given landing spot, but would prefer to have more time in the air (for various reasons), which would likely be a slower speed. AN6-25 BOLT 1-2550 BUSHING AN310-6 NUT AN945-6P WASHER. The math looks like this: 9114.18 ft /1000 ft = 9.11418. It can be used for spin training with tailweights added. And, on a side note, do any of you happen to know the glide ratio for a 7GCAA? Like the original, it can handle a hefty 17-knot crosswind. The only effect weight has is to vary the time the aircraft will glide for. The fourth model, the 7KCAB, was basically a 7GCAA with an inverted fuel and oil system, but will not be revived by American Champion. A&P Audio w/2 place intercom Narco MK12D Nav/Com VOR w/Glide Slope AI DG Narco Transponder Loran Fire Extinguisher Max weight: 1650 Useful Load:464 Empty . While the Citabria designs remain successful, and the introduction of the 7KCAB variant of the Citabria had added limited inverted flight capability, the Citabrias are not capable of "outside" maneuvers, those requiring significant negative-g loads. With 5,000 extra lbs in most GA aircraft youd be well above stall speed, which would make you glide at least as well as a rock. Fuel Burn at 75% power in standard conditions per hour. . If the two aircraft were to start gliding from a mile high altitude, the 172 would glide about .8 miles further than the phantom. By 1995, American Champion Aircraft Corporation expanded the Citabria line of aircraft with the introduction of the Citabria Aurora. [2] It was a parasol winged monoplane, with a revised wing section and a longer fuselage. Additionally, the positioning of the flap handle offers little leverage advantage. Per the C180 owner's manual, sea level best rate is listed as 87 - 90 mph. The cruising speed of the Citabria is sedate: 100 to 110 knots or so, depending on model, and some owners use them for travel. HOLY COW!! the glide ratio is independent of the weight or mass of the aircraft. The only thing that has changed is the rate at which the plane is proceeding along the glide path. 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. The model 7ECA Citabria entered production at Champion in 1964. Just as when you are under power. To Mark, JAN 10, 2013: Slipping as needed with partial flaps worked quite well, maintaining a final approach speed of 56 knots indicated. the heavier plane will reach the ground faster. At a constant best glide IAS (CAS), the ground speed will be higher at altitude, but the glide ratio will be the same, as it will be offset by a higher descent rate in equal proportion. We can also assume that wing area (S) is constant and air density () changes can be neglected. Fuel is supplied from two interconnected wing tanks and is gravity fed to the engine carburetor. Power Plant: Lycoming O-320-B2B. The Aeronca Model 7 Champion, more commonly known as the Champ, is a single-engine, two-seat, fixed conventional gear airplane. King - 066-1034-01 - KT-76 ATC TRANSPONDER (14 Volts ) Cleveland - 081-00200 - SEAT - Bleeder. (You must log in or sign up to reply here. Welcome Guest. (Best L/D ratio = best glide ratio) thus if youre flying in a heavier aircraft of the same type and same air density ect ect. American Champion's 7GCAA, reintroduced in 1997 as the Citabria "Adventure," is similar to earlier versions, with the exception of the metal-spar wings and the use of the Lycoming O-320-B2B engine of 160 horsepower (120kW); the most recent significant design change has been the switch to aluminum main gear legs in 2004. They're located in Rochester, Wisconsin (262-534-6315), or on the web at www.amerchampionaircraft.com. 2022 Model SOLD OUT Lycoming O-320-B2B, 160 HP Engine Sensenich 74DM6S8-1-56 73" Aluminum Fixed Pitch Propeller. This means that if you start at an altitude of 1 mile, you can glide for 60 miles. (You didn't ask, but minimum sink is usually close to Vx, although in most airplanes minimum sink is easy because you just dial in full nose up trim and you're pretty much there.).
