APU FAULT due to “No Flame Shutdown” - The increase in APU exhaust gas temperature (EGT) does not rise more than 100°F (37.8°C) for 23 seconds and the APU speed is more than 7% during an APU start cycle. Aircraft will be dispatched iaw MEL 49-01 APU inop. You can see APU BITE (built-in test equipment) to confirm that the APU Fuel Valve operates normally (there is fuel flow). Another engineer is inspecting the APU during the start. If the APU Fuel Valve isn’t operating, aircraft would need to be

Uncover the APU showdown between Boeing and Airbus 🔧✈️ — two very different philosophies in aviation engineering. The Auxiliary Power Unit (APU) isn’t just a backup engine; it’s a critical lifeline for electrical power and air systems when the main engines aren’t running. Airbus takes redundancy to the skies, with APUs certified to operate even at cruise altitudes above 35,000 feet — giving pilots extra safety options during emergencies. Boeing, on the other hand, leans into weight efficiency a

Check out this video showcasing the Auxiliary Power Unit (APU) starting up on an aircraft. Notice the smoke coming out from the APU exhaust? What’s Happening? I think , It’s primarily due to the combustion process as the APU powers up, especially if the unit hasn't been used recently. Importance of APU ! - Provides electrical power and air conditioning while the aircraft is on the ground. - Supplies bleed air to start the main engines. - Enhances passenger comfort and operational efficiency.

Multiple crew reports of APU auto shutdowns triggered a focused inspection of the ignition system. Igniter plugs and leads were replaced to eliminate potential high-energy ignition faults and ensure reliable light-off, proper flame detection, and stable combustion during start and operation. On the A320, the APU is a self-contained gas turbine that provides electrical power and pneumatic bleed air on the ground - and as backup in flight if required. It supports engine starts, powers aircraft sys
