What does the Rate of Climb Indicator measure in units?

The Rate of Climb Indicator measures the vertical speed of an aircraft in feet per minute. This measurement is crucial for pilots as it provides them with information about how quickly the aircraft is ascending or descending. Understanding the rate of climb helps pilots make informed decisions during takeoff, ascent, and approach to landing. The unit of feet per minute is standard in aviation for expressing vertical speed because it gives a clear and concise indication of how fast an aircraft is gaining altitude or losing height over time. Other units such as feet per second or knots per hour do not align with the conventional usage in aviation for this particular parameter.
