DescriptionA slip occurs when the bank angle of an airplane is too steep for the rate of turn. The airplane is in essence flying sideways, increasing drag and therefore increasing the rate of descent without increasing the airspeed.
ObjectiveThe student should develop knowledge of the elements related to forward slips, as well as sideslips and have the ability to perform either on. The private pilot student should have the ability to perform the forward slip to a landing as required in the PTS.
Procedure• Prepare for landing. Complete before landing checklist. Note wind direction for proper execution.• Execute forward slip. Turn final at a higher than normal altitude. Apply carb heat and reduce power to idle. Lower the upwind wing using aileron input. Apply opposite rudder to keep airplane from turning. Adjust pitch to maintain an approach airspeed of 70 KIAS.• Transition to normal approach. Forward slip will not be continued below 50ft AGL. Once normal glide path is obtained via two red, two white on the PAPI or red over white on VASI: simultaneously neutralize aileron and rudder input and align aircraft with centerline. “Heels on the floor and back” must be verbalized by the pilot flying on short final or go-around must be initiated.• Flare and touch down. Add flaps as necessary and continue landing as normal.
ACS Standards• Complete the appropriate checklist.• Make radio calls as appropriate.• Plan and follow a flightpath to the selected landing area considering altitude, wind, terrain, and obstructions.• Select the most suitable touchdown point based on wind, landing surface, obstructions, and airplane limitations.• Position airplane on downwind leg, parallel to landing runway.• Configure the airplane correctly.• As necessary, correlate crosswind with direction of forward slip and transition to sideslip before touchdown.• Touch down at a proper pitch attitude, within 400 feet beyond the specified point, with no side drift, and with the airplanes longitudinal axis aligned with and over the runway center/landing path.• Maintain ground track aligned with the runway center/landing path.
