The major improvement in Bellanca's introduction of the Super Decathlon was the change of engine to the Lycoming AEIO-360-H1A or H1B, both of 180 horsepower (130kW), which was accompanied by a selection of constant speed propellers. Further improvements to the 7GCBC include use of the heftier front wing strut from a Decathlon, which is attached to the wing with a beefed-up end fitting. Just as when you are under power. 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. 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. How to stop ignition interference on radio. The Citabria is based on the Champion 7-series airframe. N574KS, Glider: GrobG 102 Astir CSTail #: No one expects an air cooled 160hp with a carb. 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. The landing gear of the Citabria is in a conventional arrangement. A sport pilot may: Share the operating expenses of a flight with a passenger, provided the expenses involve only fuel, oil, airport expenses, or aircraft rental fees. Yes, L/D is L/D always. The airspeed and angle of attack are related directly, yes ? Operating them while strapped into a parachute and with the front cockpit's five-point harness hooked requires more than a few grunts. Ours had all spraying equipment removed. A "High Country Explorer" version, with a Superior Vantage O-360-A3A2 engine of 180 horsepower (130kW) and larger wheels, is also produced by American Champion. Aircraft weight, air density (e.g. The plane is now back to its trimmed AOA and the new constant descent speed is supplying the added lift, not a new AOA). Bellanca introduced two designs with close connections to the Citabria: The 8KCAB Decathlon and the 8GCBC Scout. A C172 w 9.5/1 glide ratio (L/D) has a 6.01 deg. Aircraft.com is the leading registry for planes, jets, and helicopters. 40 or more to one for single seaters has been common for 30 years or so. Vy in your airplane is 69 mph. Description: Our Club purchased this glider simulator in 2019 for our students from Russell Holtz. Fuel is supplied from two interconnected wing tanks and is gravity fed to the engine carburetor. Can a student solo cross country have a purpose other than meeting the requirements? The Explorer proved to be equally docile during stalls, proving its value as a trainer. If the C-172 has an L/D of 9.5. The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. Would it be the same as your best climb? I would really appreciate if you could help me out. [2] He took off from an airstrip at William Barron Hilton's Flying-M Ranch, about 70 miles (110km) southeast of Reno, Nevada. The glide ratio varies with air speed, but there is a maximum value which is frequently quoted. A wide panel holds all the latest avionics we're in 1968, so that includes a . #20. The last two positions, 27 degrees and 35 degrees, are a tough pull. The lighter? Reduce power but maintain altitude, reduce power some more, maintain altitude. 4. 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. GlobalAir.com is your partner in connecting you with relevant information and resources. Tracking the runway centerline required little effort. I couldn't find a glide ratio for a spitfire. I used the following estimates. The Decathlon entered production at Champion in 1972, immediately before the company was acquired by Bellanca Aircraft Corporation, so only a handful were produced by Champion. 4 products. An orificed one-way check valve allows a minimum of fuel to be vented overboard during negative G aerobatic maneuvers. . To facilitate negative-g flight, the fuel system incorporates a 1.5 gallon header tank beneath the instrument panel, and the engine is fitted with a Christen Industries inverted oil system. SAVE Last Update: 02/24/2023. Well I stuck my neck out on this one. Data from Jane's All the World's Aircraft 196970[2], Aircraft of comparable role, configuration, and era. Do you have the glide ratio in your book? It's easier from the back seat, but that's not where you solo this aircraft. Length: 22 9. So based on the information above. Introduced in 1965, the Champion 7GCAA, like the 7ECA, featured wood-spar wings and oleo-shock main gear. Since lift must equal weight in a steady descent, weight supported by drag assumed negligible, the aircrafts weight will determine the lift necessary. Sign in while the glide angle can change but glide ratio will stay the same. Champion introduced the 7GCBC in 1965. Older Citabria 7GCBC aircraft produced in the 1960s and 1970s had wood spars that are prone to cracking. 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! Page 6-Engine Out Glide Distance? 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.? 1111, Glider: CentrairPegasus 101BTail #: The landing gear of the Decathlon is in a conventional arrangement. $85,500 Reg# N8552V TT: 2408; Performance Specs. The first quoted paragraph said; 1. We use cookies to help you get the best experience when using our website. Citabrias were also popular as trainersbecause of their conventional gear and their aerobatic capabilitiesand as personal aircraft. Said for years..every pilot should know his best glide, write it on your dash. Its name spelled backwards, "airbatic", reflects this. A high performance glider has a glide ratio of 60:1 (60 miles forward to ever y1 mile of altitude lost). Increased wing rigidity is to blame for the float, Mehlhaff, Jr., said. . Because the AOA remained unchanged, this once again perfectly balanced plane will remain on its same glidepath and arrive at the same touchdown point. 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. The extra weight is balanced by the extra lift Perhaps I am to understand that angle of attack stays the same in best glide, 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. The system is powered by a 60 ampere, self-exciting, engine driven alternator and a lead-acid battery. (The Citabria was certified under older CAR 4a regulations, when a more extensive flight manual was not required.) Weight opposes lift, it does not oppose drag. hope this might help. We powered pilots often call this Vg or Vbg. Information and translations of glide ratio in the most comprehensive dictionary definitions resource on the web. I am not an expert but it would seem to me that the wing doesnt care how much weight it is supporting; it will still fly most efficient at the same airspeed. When introduced, it featured wood-spar wings and oleo-shock main gear. The outer shape of the fuselage is created by a combination of wooden formers and longerons, covered with fabric. . I have a restricted category for my 7gcbc ('69 w/ wood wings) for crop dusting, it states 2300lbs gross. Someone on the internet gave a Vbg of 135MPH for a total glide time of 60 * (6/135) = 2 minutes 40 . Designed for flight training, utility and personal use, it is capable of sustaining aerobatic stresses from +5g to -2g. It's fair to say the Citabria goes back a waysall the way to the beginning, in fact. Drag is apposed by thrust. - MOUNT ENGINE SET OF 4. The glide ratio varies with air speed, but there is a maximum value which is frequently quoted. Examples of how to use "glide ratio" in a sentence from the Cambridge Dictionary Labs Take a scenic flight to a favorite restaurant with a "greenhouse" view from the front cockpit (especially if it has the $500 sunroof option), and have an aileron roll along the way as an appetizer. 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. IF IM WRONG SOMEBODY OUT THERE PLEASE SET ME STRAIGHT. Aircraft Owners & Pilots Association Find it free on the store. tan(glide angle)=alt/distance. Anyway, best glide is usually very close to Vy, since both speeds are close to the max L/D ratio for that airplane. BUT Most think this is blasphemy, so take it with a grain of salt: 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. Within the first year of production, Champion began offering the Lycoming O-235-C1 engine of 115 horsepower (86kW) as an alternative to the Continental. Further practice would reduce the landing distance still further. Why? Instead of best glide SPEED, memorize best glide ATTITUDE. (You must log in or sign up to reply here. People should practice engine-outs by landing with idle power whenever possible. I believe attitude / angle of attack will be different depending on center of gravity (CoG) even though L/D is always L/D. Agree, especially if you mean the hershey bar variety. 10-11:1 otherwise. Vy in your airplane is 69 mph. If you have a GPS just hold an airspeed, throttle back, decend a fixed amount and see how far you went. The winds would have to be factored in as well. Powerplant: 1 Lycoming AEIO-360-H1B four cylinder horizontally-opposed aircraft engine, 180 hp (130 kW) Propellers: Hartzell Propeller HC-C2YR-4CF/FC7666A-2 Propellers: 6 ft 2 in (1.88 m) diameter Performance Maximum speed: 155 mph (249 km/h, 135 kn) at sea level Cruise speed: 141 mph (227 km/h, 123 kn) And possibly the worst braking system known to man; Van Sickle drums and a single handbrake. View photos, ownership, registration history, and more. I am all about learning so help me out here. The prototype had an open cockpit for a single pilot, but the design allowed for conversion to a two seat layout. Demonstrated Crosswind Component: 17kts. 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. THE ONLY THING WEIGHT DOES IS BRING THE PLANE DOWN THE GLIDE PATH AT A FASTER RATE. The 7GCAA and 7GCBC variants, added in 1965, were joined by the 7KCAB in 1968. Custom Doggy Mat. The American Champion Super Decathlon uses the AEIO-360-H1B, along with a constant speed propeller. Remains of the plane were found 13 months later near the town of Mammoth Lakes, California, just south of the original search area. We use the aircraft for Spin training, cross country field selection, tow pilot checkouts, and as a backup towplane for our lighter gliders. Champion 7ECA Citabria - 1 . This Bellanca Citabria is ready for an afternoon of fun! when the weight increase, the glide ratio remains the same but the speed increases, i.e. WHAT HAPPENS IF WE INCREASE THE WEIGHT THE VERY MOMENT THE GLIDE STARTS? Citabria 7ECA. ). One glide I did from 7500' down to the surface at ~800 MSL resulted in an 11.54 glide ratio. Let me know what you think. 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. Merry Christmas everyone! 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. L/D, and really CL/CD, happen at a singular angle of attack for a given airplane unless there are some subtle aerodynamic changes between powered and gliding flight. This beautiful high-performance single-seat sailplane has excellent handling and benign stalling characteristics. How do you determine the best engine off glide ratio in a gyro? . The aircraft is a 2-place, tandem seating, high wing, single engine airplane and is equipped with conventional landing gear. 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. The added weight requires more lift. Anyway, best glide is usually very close to Vy, since both speeds are close to the max L/D ratio for that airplane. ). Our glider has blocks that can be rotated in front of the rudder pedals to accommodate shorter legged people. PN: 1-2550 Alt_PN: AN6-25. To aid in getting down, it is recommended that power be reduced to idle opposite the point of intended touchdown. A Cessna 172 might glide at 8:1, so it could go 8000 feet forward for each 1000 feet it lost at a Vg of 65 knots indicated (KIAS). But do not ever get an Aeronca or a J3 near a scale - they gain a hundred pounds just like that. The model 7ECA Citabria entered production at Champion in 1964. 7ECA, Citabria Standard, Citabria Aurora. Slow flight was performed at 35 to 40 knots with flaps down. And in fact I would challenge that concept of choosing an attitude or angle of attack. YOU GET THERE QUICKER. Its name spelled backwards is, "airbatic". A modern German counterpart about 33:1. Demonstrated Crosswind Component: 17 kts. The following formula is used: = S / H where: = Glide Ratio S = distance of forward travel When American Champion reintroduced the 7ECA in 1995 as the Citabria "Aurora, " the biggest change was the use of metal-spar wings; the most recent significant design change has been the switch to aluminum main gear legs in 2004. I also know there is a direct relationship between AOA and airspeed. Brian; Not airspeed Joe, Angle of Attack. Early Citabrias were fitted with a steel tube main gear which uses an oleo strut for shock absorption. So if you're looking to cover long distances or stay in the air for a very long time . flyingcheesehead, Dec 21, 2011. Fuel Capacity: 36 gal. Now that I think of it, I could carry an extra 5,000 lbs.
