Remove the pressure from auxiliary pitot system No. 2.
(m)
Pressurize auxiliary pitot system No. 1 to between 4.35 and
4.45 psig (29.99 to 30.68 kPa) (410 to 415 knots) (AMM 34-11-00/201).
NOTE: Use airspeed values only when the static pressure on the
____ airspeed indicator is open to ambient pressure.
(n)
Do the above steps again to push and pull the captain's control column.
(o)
Make sure that the sums of the forces are as follows: 1) 48 to 60 pounds (213 to 267 newtons) for elevator movement of 2.10 | 0.05 inches (53.3 | 1.3 mm).
2) 102 to 125 pounds (454 to 556 newtons) for elevator movement of 6.85 | 0.05 inches (174.0 | 1.3 mm).
