Objective: To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with forward slip to a landing.

Knowledge — The applicant demonstrates understanding of:

PA.IV.M.K1 Concepts of energy management during a forward slip approach.

PA.IV.M.K2 Effects of atmospheric conditions, including wind, on approach and landing performance.

PA.IV.M.K3 Wind correction techniques during forward slip.

PA.IV.M.K4 When and why a forward slip approach is used during an approach.

Risk Management — The applicant is able to identify, assess, and mitigate risk associated with:

PA.IV.M.R1 Selection of runway/landing surface, approach path, and touchdown area based on pilot capability, aircraft performance and limitations, available distance, and wind.

PA.IV.M.R2 Effects of: Private Pilot for Airplane Category ACS (FAA-S-ACS-6C) 34

PA.IV.M.R2a a. Crosswind

PA.IV.M.R2b b. Windshear

PA.IV.M.R2c c. Tailwind

PA.IV.M.R2d d. Wake turbulence

PA.IV.M.R2e e. Landing surface/condition

PA.IV.M.R3 Planning for:

PA.IV.M.R3a a. Rejected landing and go-around

PA.IV.M.R3b b. Land and hold short operations (LAHSO)

PA.IV.M.R4 Collision hazards.

PA.IV.M.R5 Low altitude maneuvering, including stall, spin, or controlled flight into terrain (CFIT).

PA.IV.M.R6 Distractions, task prioritization, loss of situational awareness, or disorientation.

PA.IV.M.R7 Forward slip operations, including fuel flowage, tail stalls with flaps, and airspeed control.

PA.IV.M.R8 Surface contact with the airplane’s longitudinal axis misaligned.

PA.IV.M.R9 Unstable approach.

Skills — The applicant exhibits the skill to:

PA.IV.M.S1 Complete the appropriate checklist(s).

PA.IV.M.S2 Make radio calls as appropriate.

PA.IV.M.S3 Plan and follow a flightpath to the selected landing area considering altitude, wind, terrain, and obstructions.

PA.IV.M.S4 Select the most suitable touchdown point based on wind, landing surface, obstructions, and airplane limitations.

PA.IV.M.S5 Position airplane on downwind leg, parallel to landing runway or selected landing surface.

PA.IV.M.S6 Configure the airplane correctly.

PA.IV.M.S7 As necessary, correlate crosswind with direction of forward slip and transition to side slip before touchdown.

PA.IV.M.S8 Touch down at a proper pitch attitude, within 400 feet beyond or on the specified point, with no side drift, and with the airplane’s longitudinal axis aligned with and over the runway center/landing path.

PA.IV.M.S9 Maintain a ground track aligned with the runway center/landing path.
