In aviation, slow flight is the region of flight below the maximum lift to drag ratio, where induced drag becomes more significant than parasitic drag. Slow flight can be as slow as 3-5 knots above stall airspeed. Slow flight is sometimes referred to as the “region of reversed command” or the “back side of the power curve”. This is because in slow flight, more power is required to maintain straight and level flight at lower airspeeds. A very high angle of attack is required to maintain altitude in slow flight.
