Forward Slip to a Landing
Private Pilot ACS · Area IV · Task M · POH/AFM, FAA-H-8083-3
Everything you need to know about Forward Slip to a Landing for your private pilot checkride. Aligned to FAA-S-ACS-6C Task IV-M, covering forward slip to a landing.
Purpose & Technique §
Purpose: Lose altitude rapidly without increasing airspeed. Used when too high on final or when flaps are unavailable.
Technique: Apply aileron in one direction (wing drops), then opposite rudder (nose yaws away from bank direction). The aircraft slides sideways through the air, creating significant drag. Airspeed is controlled by how much rudder is applied.
Check POH for flap limitation during slips. Some aircraft prohibit full-flap slips. Some prohibit any slip with flaps extended due to possible elevator blanketing from flaps.

Forward Slip vs Sideslip §
Forward slip: Aircraft's nose points to one side of its actual flight path. Used to lose altitude without gaining speed.
Sideslip (crosswind landing): Aircraft's nose is aligned with the runway but the aircraft is crabbed. Used to correct for crosswind drift.
In a forward slip: the ASI may be partially blocked by the fuselage — airspeed indication may be unreliable. Know your aircraft's specific behavior.
