A forward slip to a landing is used primarily to
Choices
increase airspeed quickly during a go-around.
Slips DECREASE efficiency, they don't accelerate the airplane.
✓ lose excess altitude on final approach without gaining airspeed, by using cross-controlled inputs.correct
rudder one way, opposite aileron) to increase drag. A forward slip lowers the airplane on a steep descent path without speed buildup. Use opposite rudder to yaw the nose, opposite-direction aileron to maintain ground track. The high drag from the misaligned fuselage allows steep descent at safe IAS — useful when too high on final or to clear an obstacle.
compensate for a tailwind on takeoff.
Tailwind on takeoff requires turning into wind, not slipping.
shorten the takeoff roll on a short field.
Slips are a landing/descent tool, not a takeoff tool.
