citabria glide ratio

But a lovely bird. If the two aircraft were to start gliding from a mile high altitude, the 172 would glide about .8 miles further than the phantom. HOLY COW!! View photos, ownership, registration history, and more. Interested in buying this aircraft click here. And, on a side note, do any of you happen to know the glide ratio for a 7GCAA? Said for years..every pilot should know his best glide, write it on your dash. The only thing that has changed is the rate at which the plane is proceeding along the glide path. 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. 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. (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. B) increase Pilot's operating manual: Bellanca Citabria, 1975-1977 Series. Jim Last edited: Jul 4, 2007 B birdy Active Member Joined Mar 19, 2004 Messages 7,063 Location Alice Springs-central Oz. Congrats to Ian and CFI Scott for checking this box off his list. 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. There were 1,214 Citabria 7GCBC aircraft produced before Bellanca Aircraft Corporation ceased production. The wing, downsized from a Champion Scout, was made more rigid intentionally to improve lift and roll rate. WHAT HAPPENS IF WE INCREASE THE WEIGHT THE VERY MOMENT THE GLIDE STARTS? Ceiling: 17,000. The weight is no longer a factor in this scenario. 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. Compared to the Citabria's wingspan of 33.5 feet (10.2m), the Decathlon's wingspan is shorter, at 32 feet (9.8m). 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. So based on the information above. It's not a fixed number and the 50:1 ratio will only be achieved at one speed. I would really appreciate if you could help me out. Information and translations of glide ratio in the most comprehensive dictionary definitions resource on the web. What gives? Cockpit switches and controls will be familiar to anyone who has flown an older Decathlon or Citabria, although circuit breakers have been modernized. History. Bellanca continued production of the Decathlon throughout the 1970s, moving to the Super Decathlon variant during 1976. (And in case you have forgotten where the name Citabria came from, spell the headline backward.). the heavier plane will reach the ground faster. Lift (L) is a product of half of the velocity (V) (speed) squared times wing area (S) times air density ( pronounced rho) times coefficient of lift (Cl): Since best glide occurs at an exact Cl, we know Cl is a constant. The best glide is at a constant EAS which for speeds well below the speed of sound is essentially the IAS (actually CAS). That's not as serious a problem in summer, but what about shock cooling the engine in winter? Recommended Engine TBO: 2000 hours. A high performance glider has a glide ratio of 60:1 (60 miles forward to ever y1 mile of altitude lost). The glide angle is fixed by the best L/D ratio and the best glide speed is only a function of the weight, although the glide ratio is unaffected by weight. 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. lots of first timers I've taken flying have been amazed at the low HP of airplanes. JavaScript is disabled. The cross-section of the metal fuselage truss is triangular, a design feature which can be traced all the way back to the earliest Aeronca C-2 design of the late 1920s. A typical commercial airliner will glide at a ratio of about 3:1. 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 7GCAA was basically the same as the 7ECA, but with a 150-hp engine. The 7GCBA (ag spray plane) is certified to 2400lbs (I admit I know nothing about it's structure). 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. 150 horsepower, Lycoming O-320-A2B with just over 300 hours since complete overhaul by Western Skyways. If the C-172 has an L/D of 9.5. Youre right, flying the correct attitude is a much better approach to flying the aircraft during emergencies than trying to focus on maintaining a specific indicated airspeed. 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. Description: The G102 Astir is a single seat fibreglas 15m Standard Class sailplane with a retractable wheel, designed by and built by Grob Aircraft, with the first flight in December 1974. It has a claimed maximum L/D = 41. The Glide Ratio calculator computes the glide ratio based on the change in forward distance and the change in altitude. Custom Doggy Mat. The Citabria POH/AFM is a piece of junk, isn't it? 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. The L/D ratio and the glide ratio are always equal in steady-state linear unpowered flight in still air, but they are not equal if there is some thrust from a motor. for approved maneuvers in the acrobatic category. Gliding is a descending, opposite of climbing, which is ascending. Champion 7ECA Citabria - BUSHING. flyingcheesehead, Dec 21, 2011. ). 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). They're located in Rochester, Wisconsin (262-534-6315), or on the web at www.amerchampionaircraft.com. Airspeed-65 MPH recommended (60 MPH minimum) 2. 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. Sign in Our FLSC Pegasus is a B model that has a carbon fiber main spar, Introduced in 1964, the 7ECA was the first version of the design and utilized the Continental O-200-A engine of 100 horsepower (75kW). 3. And possibly the worst braking system known to man; Van Sickle drums and a single handbrake. "It reduces a lot of problems," Mehlhaff, Jr., said. In this example, the glide ratio provided in the POH comes out . [2] He took off from an airstrip at William Barron Hilton's Flying-M Ranch, about 70 miles (110km) southeast of Reno, Nevada. 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. Birdyspot on. 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. Remains of the plane were found 13 months later near the town of Mammoth Lakes, California, just south of the original search area. Cruise Speed/Endurance with45 MinReserve @ 75% Power: 127mph/ 2.8 hrs, Fuel Consumption(55% to 75% Power, per Lycoming Data): 7.3 to 10gph. (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.). 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! . Variations in aircraft weight do not affect the glide angle . 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. 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. Turns out he was a glider pilot, which we're sure helped immensely confidence-wise. 1111, Glider: CentrairPegasus 101BTail #: SECOND THE SPEED VARIABLE: I know the AOA did not change. Perversely, adding weight means that the best glide angle occurs at a faster speed. This just doesnt seem to jive. Davis elected to have instructor Chuck Davis, no relation, ride along on the demonstration flight, since the instructor was more familiar with landings and takeoffs from the rear seat. 1. How do you determine the best engine off glide ratio in a gyro? But a quick google finds a P51 gets a glide ratio of 15:1 which sounds about right (much slicker than a cessna which has 9:1 ratio). Arrow is famous for a safe glide ratio - glides like a safe. ? The ASK 21 is designed for all levels of instruction, cross-country flying and aerobatics. Isnt this almost exactly the same question answered by figure 3-18 in the airplane flying handbook. $145.00/hr. With no other changes the plane starts too fall. 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. Maximum speed: 162 mph. Note as you have increased your IAS (v2) a subsequent decrease in your Angle of attack (cL) is required. Formally Quest Aircraft, the Daher Kodiak 100 was first introduced in 2008 as a rugged off airport single engine turboprop aircraft. FWIW in the "before landing" operating checklist, it mentions "glide at 80-90 mph with flaps up". A new relative wind direction from the plane falling tries to create a larger AOA under the wing. To BART, Jan 10, 2015: An extremely expensive, highly competitive glider today can have a 60:1 glide ratio. Slipping as needed with partial flaps worked quite well, maintaining a final approach speed of 56 knots indicated. So what does all this gibberish mean, right? Do you disagree? Why should I think its not on the exact same glidepath now? Bellanca continued production of the 7KCAB as the Citabria "B" Package (a designation apparently begun by Champion). The major differences between these two models are that the 7GCBC has a wingspan of 34.5 feet (10.5m), 1-foot (0.30m) longer than the 7ECA and 7GCAA, and carries wing flaps. The American Champion Super Decathlon uses the AEIO-360-H1B, along with a constant speed propeller. a 7 deg angle (glide path) gets you 1366 feet less ~ While the Explorer is fully aerobatic, although with a restricted weight-and-balance envelope when flown for aerobatics, the flight manual warns of loss of oil pressure and oil during negative maneuvers. Lighter Total system is now 3 lbs. They also now manufacture the Citabria Adventure and the Citabria Explorer. Glide ratio usually varies little with vehicle load; a heavier vehicle glides faster, but nearly maintains its glide ratio. In addition, metal ribs were nailed to spars, but the nails would pull out. Holy Smokes thats a good question! If you wish to make some sort of pursuasive argument then post up some horrid examples of glide ratios for twins. it only depends on its shape, and mostly on the shape of the wings, e.g. 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.
