List of top Flight Mechanics Questions on Airplane Performance asked in GATE AE

An aircraft starts gliding in power-off condition at an altitude of 4 km. Given that the maximum lift to drag ratio of the aircraft is 15, the maximum glide range that the aircraft can cover, measured along the ground, is _______ km (rounded off to the nearest integer).

A jet aircraft weighs 10,000 kg, has an elliptic wing of span 10 m and area 30 m\(^2\). The zero-lift drag coefficient is \(C_{D0} = 0.025\). The maximum steady level-flight speed at sea level is 100 m/s. Density of air is 1.225 kg/m\(^3\), and \(g = 10\ \text{m/s}^2\). Determine the maximum thrust developed by the engine (round off to two decimals).

For the jet aircraft data provided, the speed for maximum endurance in steady level flight is \(\underline{\hspace{1cm}}\) m/s (round off to two decimal places).
