Maximum refill allowable is 1890 cubic centilitres (2 US quarts) without dry motoring
the engine.
If the oil system has to be replenished to maximum capacity and the replenishment
period has been exceeded, the engine(s) must be dry motored and the level rechecked.

C. Starting:
(1) Minimum ambient temperature for starting a cold soaked APU on the ground is
--40°C.
(2) Maximum EGT (dependant upon altitude and temperature):
S 0 to 100% RPM -- 692°C to 1038°C
(3) The APU starter motor duty cycle is as follows:
S Do not perform more than three starts / start attempts in one hour.
NOTE
Atwo -minute delaymust be observed between cranking
attempts to allow for cooling of starter and starter

F. APU Generator
The maximum permissible load on the APU generator is 40 kVA.
G. APU Indications
The APU limit display markings on the EICAS must be used to determine compliance with
the maximum limit and precautionary ranges. If EICAS markings show more conservative
limits than those specified below, the limit markings on the EICAS should be used.
