A power addition will typically require which type of rudder and elevator trim?

When performing a power addition, it is generally necessary to apply right rudder and down elevator trim. This is due to the effects of increased power or thrust on the aircraft's flight dynamics.

Increasing power results in an increase in the aircraft's yaw tendency due to asymmetric thrust, particularly in propeller-driven aircraft like the T-6B. The propeller spins in a specific direction, creating a yawing moment that tends to turn the aircraft in the opposite direction. To counteract this yaw, the pilot must apply right rudder, which will effectively align the aircraft's nose with the flight path.

Additionally, increasing power can also lead to an increase in the nose's tendency to rise, resulting in a pitch-up attitude. To maintain level flight or the desired attitude during this power addition, down elevator trim is needed. This trim provides the necessary control force to keep the aircraft in a stable flight configuration without demanding constant input from the pilot.

In summary, the combination of right rudder and down elevator trim during a power addition helps counteract the yaw and pitch tendencies, ensuring stable flight.
