2 MAE 2 Rate of Climb An aircraft's rate of climb is found as the difference between power required (for level flight) and power available from the engines. R / C = dh dt = V sin R / C = rate of climb h = altitude t = time V = airspeed = flight pathangle W = weight D = drag T = thrust T D W sin = 0 T D V W = V sin T V DV W = V sin = R / C R / C = T V DV W = P avail P reqd W = excess power W equation of motion parallel to flight path
3 MAE 2 Excess Power Excess power is the term used to describe power that can be used for maneuvers. Maneuvers may include climbing, turning, and/or accelerating. P reqd V Power available (piston) Power available (jet) P reqd V Excess Power Excess Power

4 MAE 2 Altitude Ceilings Absolute ceiling is the altitude at which the rate of climb is equal to zero. Service ceiling is the altitude at which rate of climb is 100 ft/min. P
