In aeronautics, the rate of climb (RoC) is an aircraft's vertical speed, that is the positive or negative rate of altitude change with respect to time. [1] In most ICAO member countries, even in otherwise metric countries, this is usually expressed in feet per minute (ft/min); elsewhere, it is commonly expressed in metres per second (m/s).
The first documented use of speed to fly theory was by Wolfgang Späte, who used a table of speeds to fly for different climb rates to help him win the 1938 Rhön competition flying a DFS Reiher. [ 3 ] [ 4 ] Späte is thought to have used a simplified form of the general theory that did not account for sinking air between thermals. [ 5 ]
The rate of climb measurement comes from the rate-of-air inflow or outflow from the container." [4] Variometers measure the rate of change of altitude by detecting the change in air pressure (static pressure) as altitude changes. Common types of variometers include those based on a diaphragm, a vane (horn), a taut band, or are electric based.
Best rate of climb speed with a single operating engine in a light, twin-engine aircraft – the speed that provides the most altitude gain per unit of time following an engine failure, while maintaining a small bank angle that should be presented with the engine-out climb performance data.

The leftover 40 hp is all that the aircraft has to maneuver with, meaning it can climb, turn, or speed up only a small amount. To put this in perspective, the C150 could not maintain a 2 g (20 m/s²) turn, which would require a minimum of 120 horsepower (89 kW) under the same conditions.
Hence the climb rate RC = V.sin θ = (P - P R)/W. [10] Supposing the 135 kW engine required for a maximum speed at 300 km/h is fitted, the maximum excess power is 135 - 87 = 48 Kw at the minimum of P R and the rate of climb 2.4 m/s.
The Monarch Butterfly has a very low 0.168 kg/m 2 wing loading The McDonnell Douglas MD-11 has a high 837 kg/m 2 maximum wing loading. In aerodynamics, wing loading is the total weight of an aircraft or flying animal divided by the area of its wing.
The one-engine inoperative (OEI) service ceiling of a twin-engine, fixed-wing aircraft is the density altitude at which flying in a clean configuration, at the best rate of climb airspeed for that altitude with one engine producing maximum continuous power and the other engine shut down (and if it has a propeller, the propeller is feathered ...
