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 index arrow, white triangle, on the ring is placed against the expected rate of climb at the next thermal. The variometer needle will then point to the optimum airspeed, listed on the ring, to be flown to that thermal. The greater the expected rate of climb, the more clockwise the ring is rotated, and the faster is the optimum airspeed. [1]
This can be done by finding the difference between current altitude and desired altitude, dividing the result by the desired rate of descent, and then multiplying that figure by the quotient of the ground speed (not airspeed) and 60. ((C-T)/RoD)*(KGS/60)=TOD. The result dictates how far from the destination descent must begin.
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 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 ...
Inclusive of the announced 2.5% COLA, the average monthly Social Security check will climb to $1,834.79 to enter the new year, representing an estimated increase of $44.75 per month.
The angle of climb can be defined as the angle between a horizontal plane representing the Earth's surface, and the actual flight path followed by the aircraft during its ascent. The speed of an aircraft type at which the angle of climb is largest is called V X. It is always slower than V Y, the speed for the best rate of climb. As the latter ...
