Study Notes
Avionics Ventilation System
- In normal flight in closed circuit configuration, the avionics ventilation system controls the temperature of the cooling air by regulating the air pressure.
Hot Air Pressure Regulating Valve
- If the hot air pressure regulating valve fails open, the regulation is lost, and the temperature control is compromised.
Pack Controller Failure
- If the pack controller experiences a primary and secondary channel failure, the system defaults to a predetermined temperature setting.
Trim Air Valve
- The trim air valve provides supplemental air to the air conditioning system to adjust the pressure and temperature.
Engine Flow Demand
- If engine flow demand in one zone cannot be satisfied, the minimum idle is increased to compensate for the shortage.
Air Distribution
- Conditioned air is distributed to the cockpit, cabin, and avionics systems in the aircraft.
Hot Air Fault Light
- When the hot air fault light illuminates on the air conditioning panel, it indicates a malfunction in the system.
Trim Air Type
- The trim air provides cool, dried, and filtered air to the air conditioning system.
Zone Controller Failure
- In case of zone controller primary and secondary channel failure, pack one maintains a temperature of around 10°C (50°F), and pack two maintains a temperature of around 12°C (54°F).
Air Distribution Exceptions
- Conditioned air is not distributed to the lavatories, flight deck, and cargo compartments in the aircraft.
