Appropriate power settings and V-speeds for takeoff and climb.
Appropriate power settings and V-speeds for takeoff and climb.
Bottom line
A sample takeoff briefing may include the rotation speed, using the specified or calculated manufacturer's takeoff or rotation speed (VR). In seaplanes, water rudders are normally retracted before applying takeoff power, because buffeting and dynamic water pressure during takeoff can cause serious damage if they are left down.
