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 Cessna 177 (originally Model 341) [3] was designed in the mid-1960s when the engineers at Cessna were asked to create a "futuristic 1970s successor to the Cessna 172". The resulting aircraft featured newer technology such as a cantilever wing lacking the lift struts of previous models, and a new laminar flow airfoil.
A power-off accuracy approach, also known as a glide approach, [1] is an aviation exercise used to simulate a landing with an engine failure. The purpose of this training technique is to better develop one's ability to estimate distance and glide ratios. [ 2 ]
In aviation, the maneuvering speed of an aircraft is an airspeed limitation at which the full deflection of the controls can be made at without risking structural damage. [1] The maneuvering speed of an aircraft is shown on a cockpit placard and in the aircraft's flight manual but is not commonly shown on the aircraft's airspeed indicator.
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 ...
