Best endurance speed – the speed that gives the greatest airborne time for fuel consumed. [citation needed] V BG: Best power-off glide speed – the speed that provides maximum lift-to-drag ratio and thus the greatest gliding distance available. V BR: Best range speed – the speed that gives the greatest range for fuel consumed – often ...
Drag vs Speed. L/DMAX occurs at minimum Total Drag (e.g. Parasite plus Induced) Coefficients of drag C D and lift C L vs angle of attack. Polar curve showing glide angle for the best glide speed (best L/D). It is the flattest possible glide angle through calm air, which will maximize the distance flown.
The Cessna 172 Skyhawk is an American four-seat, single-engine, high wing, fixed-wing aircraft made by the Cessna Aircraft Company. [2] First flown in 1955, [2] more 172s have been built than any other aircraft. [3] It was developed from the 1948 Cessna 170 but with tricycle landing gear rather than conventional landing gear.
The Monarch Butterfly has a very low 0.168 kg/m 2 wing loading The McDonnell Douglas MD-11 has a high 837 kg/m 2 maximum wing loading. In aerodynamics, wing loading is the total weight of an aircraft or flying animal divided by the area of its wing.
When empty, the 177B weighed 145 lb (66 kg) more than the earlier 177, with its maximum takeoff weight increased from 2,350 lb (1,067 kg) to 2,500 lb (1,135 kg). [ 1 ] [ 8 ] In 1978, Cessna built a deluxe version of the 177B, the Cardinal Classic , with leather upholstery, a table for the rear passengers, and a 28-Volt electrical system.
A straight line from the origin to some point on the curve has a gradient equal to the glide angle at that speed, so the corresponding tangent shows the best glide angle tan −1 (C D /C L) min ≃ 3.3°. This is not the lowest rate of sink but provides the greatest range, requiring a speed of 240 km/h (149 mph); the minimum sink rate of about ...
The 175 was designed to fill a niche between the Cessna 172 and the slightly heavier, larger and faster Cessna 182.The engine of the 175, a reduction drive or geared version of the O-300 (Continental GO-300) used in the 172, is rated at 175 hp (130 kW), or 30 hp (22 kW) more than the engine offered in the contemporary 172.
The Cessna 172 is a four-seat aircraft. At maximum weight it has a V Y of 75 kn (139 km/h) indicated airspeed [ 4 ] providing a rate of climb of 721 ft/min (3.66 m/s). Rate of climb at maximum power for a small aircraft is typically specified in its normal operating procedures but for large jet airliners it is usually mentioned in emergency ...
