(4) Do these steps to check the applicable switch in the right switchpack:
(a) Insert a rod under the right reverse thrust interlock solenoid latch.
1) Move the latch up off of the autothrottle brake cam.
(b) Mechanically restrain the rod to hold the right interlock solenoid off the autothrottle brake
cam.
NOTE: This will let the brake housing turn and not be limited by the solenoid.
(c) Move the right thrust lever and reverse thrust lever until the TRA value that shows on the
CDU is in the range shown in the table below (Table 502):
NOTE: The forward mechanical stop (full forward thrust) is at 84 +/-1 degrees TRA, the
idle stop is at 36 +/-0.25 degrees TRA, and the aft mechanical stop (full reverse
thrust) is at 6 +/-1 degrees TRA.
(d) Do a continuity check at the applicable switch connector.
