Region of Reverse Command (RoRC)
The Region of Reverse Command refers to a particular flight regime in which the aircraft requires a higher power setting to maintain altitude at a lower airspeed, and a lower power setting to maintain altitude at a higher airspeed. This region is encountered when the aircraft is operated at the slowest speed in level flight (or near it).
The RoRC is an important aspect of an aircraft’s performance because it has several implications for the pilot. Firstly, the pilot needs to be aware of the RoRC in order to ensure that the aircraft is operating within its safe flight envelope. Secondly, the pilot must ensure that the throttle settings are adjusted appropriately to maintain the desired altitude and airspeed.
The RoRC is typically encountered by aircraft with particular design characteristics such as high lift-to-drag ratios (L/D) and low wing loading. Generally, aircraft with high L/D and low wing loading are more susceptible to RoRC due to the increase in drag at slower airspeeds.
In summary, the RoRC is a flight regime where the aircraft requires a higher power setting at a lower airspeed and a lower power setting at a higher airspeed to maintain altitude. It is a characteristic that is encountered by aircraft with particular design features and has important implications for pilot awareness and aircraft performance.
