Pilot Engine PreStart

Check AIR SOURCE switch is set to OFF.

N/A

Set HYD TRANSFER PUMP switch to OFF. (Guard up)

N/A

EMERG FLT HYD switch to LOW,

Check for ON flag in EMER FLT LOW hydraulic pressure window.
Verify control over horizontal
and rudder control surfaces on surface position indicator.

EMERG FLT HYD switch to HIGH,

Check for ON flag in EMER FLT HI hydraulic pressure window.
Verify control over horizontal
and rudder control surfaces on surface position indicator.
Should have a higher deflection rate than LOW.

EMERG FLT HYD switch to AUTO(LOW),

Check for OFF flags in both EMER FLT LOW and HI.

ENG CRANK switch to R (Right engine).

Check for oil and hydraulic pressure at roughly 20% RPM.
Check START/VALVE caution light indication.
Switch is held in position automatically by solenoid
until engine is at roughly 50% RPM.

Right throttle to IDLE at 20% RPM.

Will automatically actuate ignition system and fuel flow.
Light off (EGT temperature rise) should occur within 5-15 secs.
EGT temperature should peak around 40-50% and not exceed 890 °C
which constitutes a hot start.

Check ENG CRANK switch returns to OFF around 50% rpm

and START/VALVE caution light turns off.
If ENG CRANK stays at R manually set it to off before 60% rpm.
If START/VALVE caution light is still on, disconnect starter air.

Check R GEN caution light turns off.

At around 59% rpm.

Check R FUEL PRESS caution light turns off.

Before idle rpm.

Check engine idle instrument readings.

RPM - 62 to 78%.
EGT - 500 °C (nominal).
FF - 950 to 1400 Pph (nominal).
NOZ position - 100%.
OIL - 25 to 35 psi
nominal, 15 minimum).
FLT HYD PRESS - 3000 psi.

Order plane captain to disconnect external electrical power.

N/A

ENG CRANK switch to L (Left engine).

When combined hydraulic pressure reaches 3000 psi switch ENG CRANK back to OFF.

HYD TRANSFER PUMP switch to NORMAL.

If it does not pressurize combined side within 10 secs,
immediately set HYD TRANSFER PUMP switch to SHUTOFF.
Will operate from flight side to maintain
combined side at between 2400-2600 psi.

HYD TRANSFER PUMP switch to SHUTOFF.

N/A

ENG CRANK switch to L (Left engine).

Check for oil and hydraulic pressure at roughly 20% RPM.
Check START/VALVE caution light indication.
Switch is held in position automatically by solenoid
until engine is at roughly 50% RPM.

Left throttle to IDLE at 20% RPM.

Will automatically actuate ignition system and fuel flow.
Light off (EGT temperature rise) should occur within 5-15 secs.
EGT temperature should peak around 40-50% and not exceed 890 °C
which constitutes a hot start.

Check ENG CRANK switch returns to OFF around 50% rpm

and START/VALVE caution light turns off.
If ENG CRANK stays at L manually set it to off before 60% rpm.
If START/VALVE caution light is still on, disconnect starter air.

Check L GEN caution light turns off.

At around 59% rpm.

Check L FUEL PRESS caution light turns off.

Before idle rpm.

Check engine idle instrument readings.

RPM - 62 to 78%.
EGT - 500 °C (nominal).
FF - 950 to 1400 Pph (nominal).
NOZ position - 100%.
OIL - 25 to 35 psi (nominal, 15 minimum).
FLT HYD PRESS - 3000 psi.

Order plane captain to disconnect starter air.

N/A

Cycle AIR SOURCE switch to L ENG, R ENG, then set it to BOTH ENG.

Verify cockpit airflow at all positions.

HYD TRANSFER PUMP switch to NORMAL.
