Airman Certification Standards
ACS PA.IV.A
Normal Takeoff and Climb
Knowledge
Effects of atmospheric conditions, including wind, on takeoff and climb performance.
Best angle of climb speed (VX) and best rate of climb speed (VY).
Appropriate airplane configuration.
Risk Management
Selection of runway or takeoff path based on aircraft performance and limitations, available distance, and wind.
a. Crosswind
b. Windshear
d. Wake turbulence
e. Takeoff surface/condition
Abnormal operations, including planning for:
a. Rejected takeoff
b. Potential engine failure in takeoff/climb phase of flight
Collision hazards.
Low altitude maneuvering, including stall, spin, or controlled flight into terrain (CFIT).
Distractions, task prioritization, loss of situational awareness, or disorientation.
Runway incursion.
Skill
Complete the appropriate checklist(s).
Make radio calls as appropriate.
Verify assigned/correct runway or takeoff path.
Determine wind direction with or without visible wind direction indicators. Private Pilot for Airplane Category ACS (FAA-S-ACS-6C)19
Position the flight controls for the existing wind, if applicable.
Clear the area, taxi into takeoff position, and align the airplane on the runway centerline (ASEL, AMEL) or takeoff path (ASES, AMES).
a. Retract the water rudders, as appropriate (ASES, AMES)
Advance the throttle smoothly to takeoff power and confirm proper engine and flight instrument indications prior to rotation.
a. Establish and maintain the most efficient planing/lift-off attitude, and correct for porpoising or skipping (ASES, AMES)
Avoid excessive water spray on the propeller(s) (ASES, AMES).
Rotate and lift off at the recommended airspeed and accelerate to VY.
Establish a pitch attitude to maintain the manufacturer’s recommended speed or VY, +10/-5 knots.
Configure the airplane in accordance with manufacturer’s guidance.
Maintain VY +10/-5 knots to a safe maneuvering altitude.
Maintain directional control and proper wind-drift correction throughout takeoff and climb.
Comply with noise abatement procedures, as applicable.
