JOINT ADVANCED MULTI-ENGINE T-44A
Engine start is a critical procedure requiring total concentration. If not performed correctly, injury to
personnel or damage to equipment may occur.
Start engines in accordance with NATOPS. Start procedures and actions (up to the After Start
Checklist) are performed from memory.
For a battery start, start the right engine first. Check the area around both engines clear and brief the
CP. P displays two fingers in the front windshield and receives start confirmation from the lineman.
P will place both feet on the brakes during the entire engine start sequence.
A typical brief would be: "This will be a battery start of the right engine. I'll time the start; you
time from condition lever at low idle to light off and monitor the fire guard. Check the right side
clear. The left side is clear and the fire guard is posted. Starting the right engine."
Right Engine Start:
Starter IGN & ENG Start
P engages right starter with right hand while simultaneously starting elapsed time clock with left
hand. Ensure RH IGN IND annunciator light is on and rotation is indicated on N1 gauge.
N1 Stabilized Above 12%
Battery Voltage 18 V or higher
NOTE: Consider terminating the start if battery voltage is less than 18 volts. If electing to continue with low
voltage, monitor ITT closely. If necessary, be prepared to secure the engine with the condition lever.
Condition lever Low Idle
P moves right condition lever to Low Idle after N1 stabilizes above 12%. P mentally counts 10
seconds as a timing back-up. CP commences timing for 10 seconds when P moves condition lever
to Low Idle.
Fuel flow Note (approximately 100 lbs/hr)
ITT and N1 Monitor
Do not remove hand from condition lever during the start attempt. If ITT is likely to exceed 925º C, move the
condition lever to Fuel Cutoff. If a stop start is required, maintain slight outboard pressure on the lever to
prevent binding on the idle stop. Start ITT must not exceed 1090º C or greater than 2 seconds.
If no rise in ITT is observed within 10 seconds, move the condition lever to Fuel Cutoff and secure the starter.
Allow 60 seconds for fuel drain and starter cooling. Select Starter Only for a minimum of 15 seconds, then allow
the starter to cool for an additional 60 seconds prior to attempting another start.
Starter -Off (50% N1 minimum)
Stop elapsed clock check starter time.
Starter use is time limited to 40 seconds on, 60 seconds off, 40 seconds on, 60 seconds off, 40 seconds on, then
30 minutes off.
Engine Instruments Check for normal indications at Low Idle.
P then signals "thumbs up" to the lineman, indicating a normal start; ensure oil pressure is at 40 PSI
(pounds per square inch) minimum. Oil pressure can exceed 100 psi for start and warmup.
Power lever Advance to 70% N1.
