eng.aircraft-climb-gradient Calculator
Calculates aircraft climb gradient from thrust, drag, and weight, and required obstacle clearance per FAR Part 25. FAR 25.121 requires minimum 2.4% gross climb gradient with one engine inoperative after V2 — this is the critical performance constraint for multi-engine certification.
Inputs
Thrust Kn
Reference formula or conversion factor shown for context.
Drag Kn
Reference formula or conversion factor shown for context.
Weight Kn
Body or object weight. For health calculators, usually in kg or lbs.
Climb Speed Ktas
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Results
climb gradient
Sample size or count used in the calculation.
rate of climb (m/s)
The value at the specified point or condition.
rate of climb (ft/min)
The value at the specified point or condition.
climb angle (degrees)
The magnitude or severity on the applicable scale.
γ = (T-D)/W
Reference formula or conversion factor shown for context.
