Study Notes
Air Conditioning System
- The mixing manifold receives conditioned air.
Fault Indication
- The hot air fault light on the air conditioning panel illuminates when there is a hot air fault.
Trim Air
- Trim air provides cool air to the air conditioning system.
Zone Controller Failure
- In case of primary and secondary channel failure of the zone controller, Pack One maintains a temperature of 10°C (50°F) and Pack Two maintains a temperature of 18°C (64°F).
Temperature Control Unit Failure
- When the temperature control unit primary channel fails, the secondary channel takes over.
Avionics Ventilation System
- The temperature of the cooling air is controlled by the pack controller.
Ram Air Switch
- The Ram air switch should be used to enable Ram air to the mixture unit when it's necessary to compensate for high bleed air temperatures.
Primary Channel Failure
- In the avionics ventilation system, a primary channel failure in the pack controller leads to a switchover to the secondary channel.
Secondary Channel Failure
- In the avionics ventilation system, a secondary channel failure in the pack controller leads to a complete loss of cooling.
Hot Air Pressure Reg. Valve Failed Open
- In the avionics ventilation system, if the hot air pressure regulator valve fails open, it results in loss of cooling.
