The LPBS and HPBS must not be used simultaneously for cabin pressurization/heating. If the LPBS
is used then limited bleed flow from the HPBS can be used for deicing purposes only. For details,
refer to the Installation Manual.
All M601 Models: Use of air bleed when using takeoff power settings is limited. In this
circumstance, 25 g/sec (3.3 lb/min) of air from the HPBS can be bled for deicing purpose only. For
details, refer to the Installation Manual.
Contamination does not exceed the following values for:
carbon monoxide: one part per 50,000 parts
