the following are all clear:
• Engine air inlet
• Generator cooling air inlet
• Engine anti-ice exhaust
• Pylon precooler inlet
• Generator cooling air exhaust
• Engine fluid drains
• Pylon precooler exhaust
Check the engine rotors (and the engine T2
probe in the engine inlet) for bent blades, nicks,
and blockage of fan stators (stationary blades).
Check the oil filter bypass indicator by viewing
the indicator button through the access
panel on the lower right side of each engine
nacelle (see Figure 7-7). If the button is extended
(popped), maintenance is required
before flight.
Open the oil door to check the oil level in the
oil level sight glass (see Figure 7-11). It should
be between MIN and MAX. The normal time
to check engine oil is 10 minutes after engine
shutdown.When finished checking the oil system,
ensure that the access doors are secure.
START
Before starting the engines, complete preflight
inspection and ensure that no
inappropriate CAS messages appear (Figure
7-28). Ensure that no blowing debris is likely
to be ingested by the engine. Verify that no aircraft
are closer than 50 feet immediately behind
the engine and that no people are within the
hazard area in front or behind the engine (see
Figure 1-4 in Chapter 1—“Aircraft General”).
NOTE
Consider wind velocity prior to attempting
engine start in order to
preclude exceeding wind-related limitations.
Reposition the aircraft if
required (see section II of the FAAapproved
AFM).
Prior to starting the first engine, review the
STARTING ENGINES checklist to prepare
for steps that will take place during the sequence.
Verify that adequate voltage is
available for the start and then press the START
button, verifying that the appropriate START
group lights illuminate. Lift the throttle trigger,
then place the lever to the idle position.
FADEC introduces fuel and energizes the ignition,
which should result in combustion.
Scan to check that all components of the start
occur and monitor ITT as it begins to rise.
Ensure that the starting limitations are not exceeded
as the engine accelerates, and always
stand ready to terminate the start, if required,
by guarding the throttle.
Check that the ITT rises immediately. If ITT
rapidly approaches 830°C or shows no rise
within 10 seconds, abort the start. Do not exceed
830°C for more than 5 seconds; and never
exceed the maximum limit of 862°C.

If engine maintenance has been performed,
air in fuel lines may cause
a hot start. Accomplish proper purging
procedures prior to attempting a
start. Be prepared to abort the start.
With the throttle at idle, on the ground, FADEC
automatically varies fuel flow as required to
maintain N2 at 48.6%. Note that the N2 display
digits change from white to green, indicating
that the FADEC start sequence is complete.
Also, verify that all EICAS indications are normal
and proceed to start the second engine.
GROUND OPERATION
When operating on the ground, maintain throttles
at IDLE, except as necessary for engine
and system checks or for taxiing.
When operating on the ground, be
aware of the hazardous effect of jet
exhaust blast on people and other
aircraft in the area. Avoid ground
maneuvers and/or power settings that
may result in damage or injury to
others in the area (see Figure 1-4 in
Chapter 1—“Aircraft General”).
When beginning to taxi, verify both brakes are
operating and nosewheel steering is effective.
