    The area of reverse command is the region on a Coefficient of Lift chart where a decrease in airspeed while maintaining a level flight altitude will result in greater drag and therefore require an increase in power/thrust in order to maintain that altitude. It’s most often seen during a slow flight maneuver where large amounts of throttle are needed so that excess thrust combines with lift to maintain altitude, but the speed remains very slow. It’s called the “reverse command” region because slower speed needs more thrust as compared to the area of normal command where more thrust will result in greater airspeed.

    The whole “pitch for airspeed, power for altitude” thing is given more attention during slow flight and final approach to landing, but I personally find that to be merely a matter of perception because it could very easily be looked at just the opposite with “pitch for altitude, power for airspeed” just as with normal cruising flight. In reality, pitch and power work together to adjust airspeed and altitude (and vertical speed) and it’s a matter of smoothly using both to get the results you need for a particular flight operation.
