The above values do not allow for flyheel windage
losses, test stand drag, or inertia of the starter.
In order to determine compliance with this specifi
cation, the test equipment must be calibrated and
specific test results corrected accordingly. If the
acceleration specified for Phase C is not developed
because of test stand drag torque, the test stand
inertia load may be reduced or external power may
be applied to assist acceleration to cutout speed.
Time from end of Phase C to starter coutout shall. not
exceed 15 seconds.

Minimum Output Drive Speed (RPM): 1800
Airflow, Max (Lb per Min): 120
Overrunning: The starter output drive shall be driven
for 1000 hours in a clockwise direction (viewed from
the anti-output shaft end) in accordance with the
following tabulation. The ambient -temperatures,
starter output drive speeds, and attitudes shall
vary in accordance with the following tabulation
while the starter pad temperature is maintained at
350F 20F. The attitude transitions are to be
completed within 30 seconds.

After 300 hours of overrunning the starter shall be sub-
jected to 300 endurance test cycles. Lubricant addition
or change is permitted only after the 300 endurance test
