Work out thrust required instantly with clear inputs, formula shown and shareable results.
In steady flight thrust equals drag, and drag equals weight divided by the lift-to-drag ratio. Climbing adds a thrust requirement equal to weight times the climb gradient, since the engines must also lift the aircraft against gravity at that rate.
Thrust required
T = W/(L/D) + W x gradient; T/W = thrust required / weight
Aviation results are planning estimates only. Always verify take-off, landing, fuel, weight and balance figures against the certified Aircraft Flight Manual, current performance charts and applicable aviation regulations before flight.
In level flight lift equals weight and thrust equals drag. Since L/D = lift/drag, drag must be weight divided by L/D.
Yes, almost linearly for shallow gradients: each 1% of gradient adds 1% of weight to the thrust requirement.
