In aviation, '''slow flight''' is the region of flight below the maximum [[Lift-to-drag ratio|lift to drag ratio]], where [[Lift-induced drag|induced drag]] becomes more significant than [[parasitic drag]]. Slow flight can be as slow as 3-5 knots above stall airspeed.<ref name=":0">{{Cite book|title=Airplane Flying Handbook|publisher=Federal Aviation Administration|year=2016|isbn=9781541058804}}</ref>

Slow flight is sometimes referred to as the “region of reversed command” or the “back side of the power curve”.<ref name=":1">{{Cite book|title=Pilot's Handbook of Aeronautical Knowledge|publisher=Federal Aviation Administration|year=2016|isbn=9781619544734}}</ref> This is because in slow flight, more power is required to maintain straight and level flight at lower [[airspeed]]s. A very high [[angle of attack]] is required to maintain altitude in slow flight.

At these low airspeeds, [[flight control surfaces]] begin to lose their effectiveness due to the reduction in airflow over them.<ref name=":0" /><ref name=":1" /><ref>{{Cite web|title=Slow Flight|url=https://www.cfinotebook.net/notebook/maneuvers-and-procedures/airborne/slow-flight|access-date=2020-10-13|website=CFI Notebook}}</ref> [[Aileron]]s are the most affected, and roll control is significantly degraded. If ailerons are used in slow flight, there is a possibility that the high wing will [[Stall (fluid dynamics)|stall]] due to the increased angle of attack, sending the aircraft into a [[Spin (aerodynamics)|spin]]. In many modern aircraft, [[flight envelope protection]] in the [[aircraft flight control system]] prevents this from happening. The [[rudder]] remains effective in slow flight, and yaw provided by it can be used to control the [[bank angle]] and direction of the aircraft.
