What it calculates
The “Aircraft Climb Rate” calculator computes Rate of climb in m/min from 5 parameters: takeoff weight (kg), engine power (kW), propeller efficiency (%), climb airspeed (km/h), lift-to-drag ratio l/d.
Trip planning, distance and time calculations.
Example calculation
With parameters Takeoff weight = 1,100 kg, Engine power = 120 kW, Propeller efficiency = 80 %, Climb airspeed = 140 km/h, Lift-to-drag ratio L/D = 10 the result is 301 m/min (Educational estimate — use the POH for a real aircraft).
How to use
