_______ YOU DO THIS, AIRCRAFT BRAKING THROUGH BRAKE PEDALS DOES NOT OPERATE.
(a) On the landing gear control and indicating panel 402VU:
- Make sure that the A/SKID & N/WSTRG selector switch 5GG is ON.
(b) Push and hold the brake pedals at the full limit position.
(c) On the RUD TRIM/PARKING BRK panel 110VU:
- Set the PARKING BRAKE control switch to OFF.
(3) Set the opposite engine that you must hot test to 60 percent N1.
(4) When the parameters become stable, move suddenly the throttle control levers from 30 percent N1 to the FLEX/MCT detent.
(5) Start the chronometer at throttle control lever movement.
(6) Stop the chronometer when N1 reaches the FLEX T/O target minus 5 percent that you recorded in step 3.B.(5).

A. Stop the engine CAUTION : MAKE SURE THAT THE ENG/MASTER 1(2) CONTROL SWITCH IS FULLY
_______
ENGAGED IN THE OFF DETENT AFTER SHUTDOWN.
(1) Before you stop the engine, operate it at or near idle for 3 minutes before shutdown to thermally stabilize the engine hot section.
NOTE : You can use taxi time at or near idle as part of the 3 minutes
____
cool down time.
(2) Put the throttle control lever in the idle position.
(3) Set the ENG/MASTER 1(2) control switch to OFF.
(4) Monitor the EGT, N2 and fuel flow during shutdown to confirm fuel shutoff.
CAUTION : BE PREPARED TO DRY MOTOR THE ENGINE WITH THE STARTER IF
_______ THERE IS A POST-SHUTDOWN FIRE INDICATION. ENGINE DAMAGE CAN BE CAUSED.
(a) Make sure that the EGT and N2 rpm decrease when the fuel is shut off. If a steady decrease in the EGT does not occur after shutdown, do a dry motoring until the fire is extinguished.

NOTE : After engine shutdown is completed, and all of the
____ rotation has stopped, the EGT will normally slowly increase. This is caused by normal temperature soak-back.
(5) On the HYD/FUEL panel 40VU:
(a) Release all the FUEL/PUMPS pushbutton switches (the OFF legends of these pushbutton switches come on).
(6) On the overhead control and indicating panel 25VU:
(a) Set the EXT LT/BEACON switch to OFF.
