How to Evaluate Rate of Climb of Aircraft?

Rate of Climb of Aircraft evaluator uses Rate of Climb = (Power Available-Power Required)/Aircraft Weight to evaluate the Rate of Climb, Rate of Climb of Aircraft is a measure of how fast an aircraft is ascending or descending vertically through the air. It represents the change in altitude per unit of time and is typically expressed in feet per minute (ft/min) or meters per second (m/s). Rate of Climb is denoted by RC symbol.

How to evaluate Rate of Climb of Aircraft using this online evaluator? To use this online evaluator for Rate of Climb of Aircraft, enter Power Available (P_a), Power Required (P_r) & Aircraft Weight (W) and hit the calculate button.

FAQs on Rate of Climb of Aircraft

What is the formula to find Rate of Climb of Aircraft?
