Sweep: Starting engine & systems
The second sweep is dedicated to starting the engine and getting all systems
online. We start again on the left console.
1. On the ELEC panel move the MAIN PWR switch out of BATT to MAIN
PWR. The lights do not change as the generators need the engine running to
provide power to the buses. Please note one of the common mistakes is to
start the jet in BATT which prevents the systems from coming online later as
the main generator is not online and may induce engine start issues. So make
sure you start this sweep with the MAIN PWR switch to MAIN PWR.
2. Moving forward you can close the canopy (spider). It is advisable to do so
before engaging the JFS. Closing canopy during JFS operation may result in a
failed JFS start or premature JFS shutdown due to a reduction in electrical
power available to the JFS. Check your throttle for its correct position (cut-off)
then move on to the ENG & JET START panel.
The JFS switch is moved to START2 with a right-click; the JFS RUN light
comes ON after a few seconds and engine RPM increases steadily to 20%. At
that point check that the SEC caution light is off and move the throttle forward
to your IDLE detent (or click the idle detent) and monitor lights and engine
gauges:
•
SEC caution light goes off around 20% RPM ( before moving the
throttle).
•
HYD/OIL PRESS light (right eyebrow) goes off between 30 and 35%
RPM.
If the light stays on and your oil pressure remains below 15 psi you
have an oil pressure fault; shut down the engine immediately and refer
to abnormal operations, chapter 3.5.4 later in this manual.
•
During engine spool up, FTIT should increase to around 600-650° then
decrease back to 500° at idle. FTIT should not go above 800°C. If you
see FTIT rising at an alarming rate or go above 750°C you are
encountering a hot start; immediately pull the throttle back to CUTOFF and let the FTIT
decrease to 200°C while the JFS is running, before attempting another engine start. Refer to
abnormal operations chapter 3.5.3 further in this manual.
•
FLCS PMG light (ELEC panel) goes off around 40-45% RPM.
•
JFS shuts off around 55% RPM (the switch automatically snaps back to OFF).
•
ENGINE light (right eyebrow) and STBY GEN light (ELEC panel) go off around 60% RPM and
MAIN GEN light (ELEC panel) goes off about ten seconds later.
With the engine running steadily you can check the engine gauges such as fuel flow (700-1700 PPH),
oil pressure (> 15 PSI), nozzle position (> 94%), FTIT (usually below 650°C but never above 800°C)
and HYD A & B pressure (at the 12
o’clock position).
With MAIN GEN online all systems should get power and the systems you previously set should come
online. You can now proceed to set the next ones.
