Abstract
This invention provides a helicopter airspeed indicating system for providing an indication of a theoretical airspeed of a helicopter in which it is fitted. The airspeed is calculated using measured weight and power values and a known relationship between power, weight and airspeed characteristics of the helicopter, and is particularly useful for providing an indication of helicopter airspeed at the low end of an overall speed range.
