PITCH NORM (20CG) (5) located on Overhead Circuit
Breakers Panel (271VE) (4) in position F 9 is closed.
4.Simulate an aircraft low speed of 100 kts by setting a
dynamic pressure of 16.3 mbar in both channels.
5.By the control wheel trim button, perform a complete
travel nose up and nose down (or vice versa) and
verify that there are no interference in the trim
actuator area, artificial feel unit and trim transmitter.
