the stabilizer movement stops. 2) Make sure the captain's STAB TRIM indicator shows
 3.0 +/- 1.0 units of trim.
 3)  Move the two STAB TRIM switches on the captain's control wheel to the NOSE UP position.
 NOTE: You will measure how much time is necessary for
____ the stabilizer to move from the upper travel limit the lower travel limit.
 4) Hold the STAB TRIM switches in the NOSE UP position until the stabilizer movement stops. 5) Measure the time necessary for the stabilizer to move from
 the upper travel limit to the lower travel limit. 6) Release the two STAB TRIM switches. 7) Make sure the stabilizer moves from its upper travel limit
 to its lower travel limit in 43 - 57 seconds.
