JOINT ADVANCED MULTI-ENGINE T-44A
P checks all engine instruments for normal indications:
a.
ITT 685 C maximum
b.
Torque 100-200 ft-lbs
c.
N2 900-1100 RPM
d.
N1 50-53%
e.
Fuel flow 100 lbs/hr (approximately)
f.
Oil temp 10-99 C
g.
Oil press 40-100 PSI
3.
AUTO-IGNITION
"CHECKED, OFF" (P)
P performs the following checks:
a.
Power levers IDLE
b.  Both ENG AUTO IGN switches-ARM (These switches have yellow rubber caps. Do not
confuse them with the starter switches.)
c.
LH and RH IGN IND annunciator lights (amber)-On
d.
Power levers Advance slowly to 500 ft-lbs torque.
e.  Ensure LH and RH AUTO IGNITION ARM annunciator lights (green) illuminate and LH and
RH IGN IND annunciator lights (amber) extinguish at 360-460 ft-lbs torque (410 50).
NOTE: If either auto-ignition system does not arm within limits during the power addition, slowly retard the
power levers and check the auto-ignition system activates within limits as power is reduced. As long as the auto-
ignition system activates within limits upon power reduction, the system checks good. Ensure the power levers
are returned to 500 ft-lbs torque.
f.
Both ENG AUTO IGN switches OFF
4.
SUCTION AND PNEUMATIC PRESSURE
"CHECKED" (P)
P ensures suction 4.3-5.9 inches Hg (5.1 + 0.8) and pneumatic pressure 12-20 PSI (16 + 4). Power
levers must be set to at least 70% N1. This should require no adjustment from position set on auto-
ignition checks.
5.
OVERSPEED GOVERNORS
"CHECKED" (P)
P performs the following checks:
a.
Prop levers full forward
b.
Power levers Set N2 less than 1900 RPM.
c.
PROP GOV TEST switch TEST (up position)
NOTE: Maintain a firm grip on the switch. DO NOT release the switch while the test is being performed. An
abrupt surge in prop rpm may result.
d.  Power levers Advance until N2 stops increasing (1900-2100 RPM). ITT and torque should
continue to increase while N2 remains stabilized. Never allow N2 to exceed 2200 RPM.
e.
Power levers Slowly retard N2 to 1900 RPM.
f.
PROP GOV TEST switch Release
