sci.climb-rate-service-ceiling Calculator
Calculates rate of climb RC = (Thrust − Drag) × V / Weight and service ceiling where RC < 30 m/min for a given aircraft configuration. Excess power at sea level for a transport aircraft is typically 3–5 m/s climb rate — at service ceiling the throttle is fully open yet available climb rate approaches zero.
Inputs
Thrust Lb
Reference formula or conversion factor shown for context.
Drag Lb
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Weight Lb
Body or object weight. For health calculators, usually in kg or lbs.
V Climb Fps
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Results
rate of climb ROC (ft/min)
The value at the specified point or condition.
climb angle γ (°)
The computed angle in degrees or radians.
excess thrust (lb)
Forward propulsive force generated by the engine or motor. Net thrust = gross thrust minus inlet momentum drag.
excess power (ft·lb/s)
Reference formula or conversion factor shown for context.
ROC = (T−D)·V / W
Reference formula or conversion factor shown for context.
climb class
The classification assigned based on the computed value.
