1. Start Page............................................................................................SELECTED
NOTE:
See Section 03-08-10, Cold Start, when oil
temperature is -10°C or less.
2. HP Fuel Cocks..............................................................................................SHUT
3. Power Levers .................................................................................................IDLE

4. Gust Lock........................................................................................................OFF
5. Beacon Switch..................................................................................................ON
6. APU Air / External Air..................................ON / PRESSURE 25 PSI MINIMUM
NOTE:
Normal air pressure for APU can vary between 25 to
50 psi. During start cycle, APU air pressure drops, but
should not drop below approximately 20 psi.
7. Fuel Boost Pumps (One Each Side) ................................ON / MESSAGE OUT
8. Electrical Power ........................................................................................CHECK
NOTE:
If using APU, limit APU alternator load (AC AUX PWR)
to 35% during engine starting. At high elevation
airports and/or high ambient temperature conditions,
limit AUX AC load to 30%.
9. Engine Start Master .........................................................................................ON
10. Engine Start Switch...................................................................................PRESS
CAUTION
CONTINUED USE OF THE STARTER IS LIMITED TO
THREE (3) CRANK CYCLES, WITH A MAXIMUM OF
THIRTY (30) SECONDS PER CYCLE. DELAY THREE
(3) MINUTES BETWEEN START ATTEMPTS. AFTER
THREE (3) CYCLES, DELAY USE OF STARTER FOR
AT LEAST FIFTEEN (15) MINUTES.
11. Start Valve and Ignition ...................................................................................ON
NOTE:
If IGN mnemonic is not displayed on EICAS, the start
may be salvaged by selecting AIRSTART IGN-ON
prior to opening HP fuel cock.
12. Positive LP RPM .......................................................................................CHECK
13. HP Fuel Cock ...............................................................................................OPEN
NOTE:
In high tailwind conditions, direction of rotation of LP
may initially be reversed and, if so, the HP fuel cock
should not be selected to OPEN until HP is stabilized.
This ensures that LP rotation is positive. Starts with
tailwinds of up to 25 knots have been demonstrated.
NOTE:
Ignition should occur within ten (10) seconds after
selecting HP fuel cock to OPEN.

14. Start Valve and Ignition .................................................................................OFF
NOTE:
Start valve should close by 44.5% HP RPM. For SPZ
8000 equipped airplanes, the SVO mnemonic
changes from blue to amber above 42% (for SPZ 8400
equipped airplanes, 44.5%) and starts flashing. Check
at ground idle HP RPM and, if start valve does not
close (“SVO” still illuminated), perform START VALVE
FAILURE TO CLOSE procedure found in Section
05-11-20, Start Valve Failure.
15. TGT..................................................................................MONITOR (700°C MAX)
NOTE:
During starting, TGT should not exceed 700°C. If there
is any evidence of rapidly rising TGT and it is
anticipated that 700°C will be exceeded, select HP
cock to SHUT immediately. If TGT has not exceeded
700°C, a second start may be attempted. If, under
normal starting conditions, TGT exceeds 650°C, this
will indicate a fault in the engine or starting systems.
16. Engine RPM..........................................................CHECK (46.6% HP MINIMUM)
17. Oil Pressure and Temperature.................................................................CHECK
18. EVM ............................................................................................................CHECK
NOTE:
The EVM system is designed to monitor engine
vibrations at idle and above. During start, the EVM
system may occasionally display momentary EVM
values above the ALERT level (0.60) which in turn
causes the EVM display digits on CAS to turn amber
momentarily (SPZ 8400 equipped airplanes). This
