Airman Certification Standards
ACS CA.IV.M
Power-Off 180
Knowledge
A stabilized approach, including energy management concepts.
Effects of atmospheric conditions, including wind, on approach and landing.
Wind correction techniques on approach and landing.
Purpose of power-off accuracy approach. 34
Risk Management
Selection of runway/landing surface, approach path, and touchdown area based on pilot capability, aircraft performance and limitations, available distance, and wind.
a. Crosswind
b. Windshear
d. Wake turbulence
e. Landing surface/condition
Planning for:
a. Rejected landing and go-around
b. Land and hold short operations (LAHSO)
Collision hazards.
Low altitude maneuvering, including stall, spin, or controlled flight into terrain (CFIT).
Distractions, task prioritization, loss of situational awareness, or disorientation.
Forward slip operations, including fuel flowage, tail stalls with flaps, and airspeed control.
Skill
Complete the appropriate checklist(s).
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 aircraft limitations.
Position airplane on downwind leg, parallel to landing runway.
Correctly configure the airplane.
As necessary, correlate crosswind with direction of forward slip and transition to side slip before touchdown.
Touch down at a proper pitch attitude, within 200 feet beyond or on the specified point with no side drift and with the airplane’s longitudinal axis aligned with and over the runway centerline or landing path, as applicable.
