4) Make sure the lockout actuator stays in the extended position (not locked out).
CAUTION: DO NOT INCREASE OR DECREASE PITOT STATIC PRESSURE
_______ MORE THAN 4 KNOTS EACH SECOND. THIS IS TO PREVENT POSSIBLE DAMAGE TO THE LOCKOUT MECHANISM.
5) Increase the pitot static pressure slowly to 245 knots minimum. 6) Make sure the lockout actuator moves to the retracted
position (locked out) in 45 seconds. 7) Turn the control wheels 80 degrees in each direction. 8) Make sure the movement of the outboard aileron trailing
edge is not more than | 0.50 degree (| 0.40 inch) from the neutral position.
CAUTION: DO NOT INCREASE OR DECREASE PITOT STATIC PRESSURE
_______ MORE THAN 4 KNOTS EACH SECOND. THIS IS TO PREVENT POSSIBLE DAMAGE TO THE LOCKOUT MECHANISM.
9) Decrease the pitot static pressure slowly to 225 knots. 10) Make sure the lockout actuator moves to the extended position (not locked out) in 45 seconds.
CAUTION: DO NOT INCREASE OR DECREASE PITOT STATIC PRESSURE
_______ MORE THAN 4 KNOTS EACH SECOND. THIS IS TO PREVENT POSSIBLE DAMAGE TO THE LOCKOUT MECHANISM.
11) Decrease the pitot static pressure to ambient.
