ACS PA.IV.K

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.

Appropriate use of rough water takeoff and climb technique.

Selection of takeoff path based on pilot capability, airplane performance and limitations, available distance, and wind.

a. Crosswind

b. Windshear

d. Wake turbulence

e. Water 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.

Gear position in an amphibious airplane.

Complete the appropriate checklist(s).

Make radio calls as appropriate.

Verify assigned/correct takeoff path.

Determine wind direction with or without visible wind direction indicators.

Position flight controls and configure the airplane for the existing conditions. Private Pilot for Airplane Category ACS (FAA-S-ACS-6C)32

Clear the area, select an appropriate takeoff path considering wind, swells, surface hazards, or vessels.

a. Retract the water rudders, as appropriate

b. Advance the throttle smoothly to takeoff power and confirm proper engine and flight instrument indications prior to rotation

Establish and maintain an appropriate planing attitude, directional control, and correct for porpoising, skipping, and increase in water drag.

Avoid excessive water spray on the propeller(s).

Lift off at minimum airspeed and accelerate to VY +10/- 5 knots before leaving ground effect.

Configure the airplane after a positive rate of climb has been verified or in accordance with airplane manufacturer’s instructions.

Maintain VY +10/-5 knots to a safe maneuvering altitude.

Maintain directional control and proper wind-drift correction throughout takeoff and climb.
