The APU start/stop switch is located near the throttle on the left console. Switch it on. Now | The APU start/stop switch is located near the throttle on the left console. Switch it on. Now check the APU's tachometer and EGT on the engine gauge panel. | ||
If the APU started successfuly you should see the EGT (Exhaust | If the APU has started successfuly you should see the EGT (Exhaust Gas Temperature) rapidly climb to 800/900°C and then stabilize when the RPMs reach 60%. | ||

Now the APU has | Now the APU has sufficient RPMs to provide electrical power through its generator. So let's turn on the APU generator. This one is on the main electrical control panel, upper left corner of the electrical control panel, right console again. | ||
With the APU generator on | With the APU generator on most of the instruments receive electrical power and now AOA indexer lights up, the HSI (the compass) and the ADI (artificial horizon) look much better. | ||
At 85% RPM the APU supplies enough bleed air | At 85% RPM the APU supplies enough bleed air to start the engines. | ||
