The Captain should continuously observe the signalman while the other crewmember monitors the engine instruments and advise if the EPR exceeds
1.3. Excessive speed can be reduced by placing the engines in forward thrust. Minor tracking adjustments and turns will be made with the nose gear steering wheel.
Upon receipt of the standard forward movement signal from the signalman, come out of reverse and apply slight forward thrust, allowing the aircraft to roll forward. Using standard signals, either stop the aircraft or continue to taxi. After powerback is complete, proceed as in Taxi-Out Gate procedure.
Taxi-Out Gate
Once the headset is removed, the headset operator shall position himself between the aircraft and the terminal building in full view of the flight deck. This could be on the left or right side of the aircraft, depending on the direction of aircraft movement.
When the Captain is ready to taxi and has received clearance to do so, he will indicate this to the headset operator/safety person by flashing the nose gear taxi light on.
The headset operator/safety person shall ascertain that the area is clear to taxi and the “Clear to Taxi” salute shall be given to the flight deck. The Captain will acknowledge receipt of this salute by turning the nosegear taxi light off. As the aircraft departs, the headset operator/safety person will give the “End of Ground Guidance” signal.
Note: In order to avoid confusion during night operations, the Captain should leave the taxi light off for 1-2 seconds before turning it back on for use during taxi operations.
Note: The aircraft will not be taxied away from a gate (or pushback position), unless the marshaller gives the proper signal that the aircraft is cleared to taxi. Should, for some reason, the marshaller not be visible, or leave his position on the ramp, the aircraft will not taxi. Call the station on company radio and have the marshaller return and give taxi clearance.
Note: Headset operator is responsible to ensure the aircraft, personnel, and equipment are clear from injury or damage from jet blast before taxi-out signals are given to aircraft. High lift trucks at gates immediately behind must be lowered before aircraft taxis out.
ENGINE START PROCEDURE
Note: The Engine Start Procedure is a coordinated effort with both the Captain and the F/O participating in engine start. The Engine Start Procedure shall be used when starting engines at the gate, during pushback or whenever both engines have been shut down. The F/O will accomplish engine start when it is required during aircraft taxi. Refer to Engine Restart Procedure.
CAPTAIN FIRST OFFICER
Call for BEFORE START checklist and accomplish assigned steps. Accomplished assigned step and read BEFORE START checklist.
Announce “STARTING ENGINE NO. ____.” Position start switch to ON and hold.
Verify increase in N2.
Verify oil pressure and announce “OIL PRESSURE” when observed.
Verify N1 rotation prior to positioning fuel lever to on.
At max motoring RPM (no N2 RPM change for 5 seconds) position fuel lever to on. 20% N2 RPM is desired, 15% N2 RPM is minimum.
Verify fuel flow and EGT indication. Monitor engine start time as described in BURNER CAN STRESS DETECTION, this section.
At 40% N2 release engine start switch -verify start valve closes and report “START VALVE CLOSED.”
Monitor N1, N2, EGT, fuel flow and oil pressure for normal indications as the engine accelerates and stabilizes at idle.
If an uncommanded acceleration to high thrust occurs, the engine must be shut down with the fuel lever.
Refer to Engine Start Notes for detailed engine start guidance.
ENGINE START NOTES
Communication with Ground Crew During Engine Start
Headset communication with the ground crew should be maintained during engine start. If headset communication is not available the Captain and ground crew should use hand signals as described in the Ops Manual.
The Captain should request clearance from the ground crew prior to starting an engine. The Captain should advise the ground crew when they are clear to disconnect external power and/or air.
The Captain should not clear the ground crew to disconnect the headset or depart the area until all engine starts are complete. This provides quick response in the event of an engine start malfunction.
