STARTING, TAXYING AND TAKE-OFF
Preliminary Checks
1. The Flight Engineer is to carry out the
Engineer’s Initial Checks
,
Internal Checks
,
Power On Checks
and
External Checks
. He is to
ensure that the external power, if available, is ON. The Captain is to
ensure that the 4 undercarriage locks are removed.
Pre-Start Checks
2. The crew will occupy their respective positions then carry out the
Pre-Start Checks
.
Starting Checks
3. After checking the intercom the crew carry out the
Starting Checks
in the challenge and response routine, referring to the FRCs. Each
propeller is to be checked clear before selecting the relevant ignition
switches to ON. Care is to be taken to identify the correct starter button
before pressing. Each engine, previously primed by the groundcrew,
should ‘catch’ within 3-8 seconds. Once the engine is running the
Captain will call ‘On the throttle’ and the PNF should then release the
starter button. Care should be taken to prevent exceeding 1200RPM.
It should be noted that considerable throttle stagger is exhibited at most
power settings. After start, each engine should be set at 700-800RPM
to allow the engine to warm up. The tendency for RPMs to rise should
be monitored and kept below 1200RPM. The engines are started in the
order 3, 4 ,2, 1.
Failure to Start
4. If an engine fails to start within 20 seconds the starter button is to
be released and the relevant ignition switches are to be switched off.
In order to permit starter cooling before a repeated start attempt, an
alternative engine may be started. If a second starting attempt fails
then engine re-priming may be considered. A maximum of 3 starting
attempts is permitted before fault analysis and a prolonged period of
starter cooling.
