What is the function of trim air?
It adds warm air to the PACK output air.
Explain the purpose of RECIRC FANs.
Recirculation fans maintain overall cabin air circulation while allowing a reduction of cabin air ventilation, permitting the PACKs to be operated at a reduced flow. This reduces bleed air demand from the engines, reducing fuel burn.
(767-300) With regard to the BULK CARGO HEAT selector, which switch position provides warmer air? NORM, or VENT? Which is the normal preflight switch position?
VENT provides a warmer compartment than NORM and activates a fan in the bulk cargo compartment. VENT is the normal preflight switch position.
Why is the center isolation (C ISLN) switch guarded on the 767?
To protect the air source to the ADP.
What is the meaning of an illuminated BLEED or HI STAGE / OVHT light?
Bleed Air Malfunction
When are probes heated?
