Do the steps that follow for the feel forces test with one auxiliary pitot system pressurized, and all hydraulic systems pressurized:

 (a)  
Remove the pressure from auxiliary pitot system No. 1
 (AMM 34-11-00/201).


 (b)  
Push the captain's control column forward until the left elevator moves down 2.10 | 0.05 inches


 (53.3 | 1.3 mm).
 (c)  
Measure and write down the control column force.

 (d)  
Pull the captain's control column aft until the left elevator moves up 2.10 | 0.05 inches (53.3 | 1.3 mm).

 (e)  
Measure and write down the control column force.

 (f)  
Make sure that the sum of the above forces is 48 to 60 pounds (213 to 267 newtons).

 (g)  
Push the captain's control column forward until the left elevator moves down 6.85 | 0.05 inches (174.0 | 1.3 mm).

Measure and write down the control column force.

 (k)  
Make sure that the sum of the above two forces is 102 to 124 pounds (454 to 552 newtons).

 (l)  
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).

 (9)  
Do the steps that follow for the feel forces test with only one auxiliary pitot system pressurized, and only two hydraulic systems pressurized:

 (a)  
Remove the pressure from the center hydraulic system
 (AMM 29-11-00/201).
