POWER BACK FROM GATE
POWER BACK FROM GATE (Procedure)
1.
Power back gate departure is only authorized when both crew members have received
proper training. A minimum of two ground crew is required, one Guideman and one
Wingwalker. The Guideman should be position in front of the aircraft, in clear view of both
pilots. The Wingwalker should be positioned aft of the right wing. Depending on the
situation and gate location, a second Wingwalker for the left wing might be required.
2.
Both engines should be running before commencing with the procedure. See the Engine
Start procedure on how to start the engines.
3.
Complete the BEFORE TAXI items on the Taxi checklist.
4.
Flash nose wheel landing and taxi light once, to indicate to the Guideman that you are
ready to begin power back. To re-establish cockpit to ground communication, flash the
nose light three times (not simulated).
5.
At the direction of the Guideman (come forward signal), taxi the aircraft two or three feet
forward, before going into reverse thrust. This is done as a safety precaution against
blocked wheels.
6.
Once the Guideman sees the aircraft moving forward, he will give the power back signal
by rotating the wands horizontally in a circular motion.
7.
Apply and hold the brakes to stop the forward motion and simultaneously set both
engines to reverse idle thrust.
8.
When both blue ENG REVERSE THRUST lights come on, release the brakes and drop both
feet to the floor.
9.
Monitor Guideman and establish reverse thrust for rearward movement. Do not exceed
1.3 EPR. Rearward speed should not exceed that of a normal walk.
10.
If rearward speed is excessive, place one engine in forward thrust.
11.
Turns during power back must be commanded by the Guideman. Upon the Guideman’s
signal, turn the steering wheel tiller in the direction of the Guideman’s lowered wand.
Turns are made with reference to the Guideman’s left or right.
12.
When the aircraft has reached the desired position, the Guideman will give the come
forward signal.
13.
Sharply come out of reverse, and apply forward thrust.
14.
CAUTION: DO NOT USE BRAKES TO STOP REARWARD MOVEMENT.
15.
Check that all reverse lights are out.
16.
On the Guideman’s signal, establish forward movement or come to a full stop.
17.
Flash nose wheel landing and taxi light once, to signal to the Guideman that you are
ready to taxi.
18.
When the area is clear, the Guideman will give the standard departure salute.
SPECIAL CAUTIONS:
•
The Guideman should never give the stop signal when the aircraft is in rearward
movement. The come forward signal should be used to stop the aircraft.
•
Do not use the brakes when the airplane is in rearward movement.
•
If the brakes are inadvertently applied during rearward movement and the aircraft starts
to tail tip, immediately move both throttles into forward thrust.
