A propeller turns clockwise as seen from the pilot seat. What does torque reaction do on the takeoff roll?

  1. It puts more weight on the right main gear and turns the airplane right
  2. It has no effect on the ground
  3. It lifts the left wing and turns the airplane right
  4. It puts more weight on the left main gear and turns the airplane left
Show answer

Correct answer: It puts more weight on the left main gear and turns the airplane left

The left tire has more ground friction, which adds a turning moment to the left. The pilot corrects with rudder.
