In the current version, the aircraft simulation | In the current version, the aircraft simulation begins with the aircraft powered down. | ||
The electrical power systems and the [[APU]]'s operation are simulated to a large extent. [[Howto: Air-Air Refueling|Air to air refueling]] is also implemented. | |||
The navigation instruments are TACAN, ILS and also a VHF so you can have homing on a VOR station. | The navigation instruments are [[TACAN]], [[ILS]] and also a [[VHF]] so you can have homing on a [[VOR]] station. | ||
Several external loads are available and the HUD provides a CCIP (Continuous Computed Impact Point). | Several external loads are available and the [[HUD]] provides a [[CCIP]] (Continuous Computed Impact Point). | ||

At FlightGear startup, both electrical power and APU are shut down | At FlightGear startup, both electrical power and [[APU]] are shut down and there is no external power supplied. | ||

You, might see, early on, some needles spinning back on the engines gauges panel and the [[VSI]]... this is only a software initialization artifact. | |||
So look at the right console, there is a panel with 6 switches, that's the Main Electrical Control Panel. Hit Ctrl-c and you will have a view of where to click... | So, look at the right console, there is a panel with 6 switches, that's the Main Electrical Control Panel.

Let's connect the battery: switch on the battery switch. A few indicators should light up, but not all of them. Now with the battery connected you can start the APU. | Let's connect the battery: switch on the battery switch. A few indicators should light up, but not all of them.

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. | 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 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%. | 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 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. | Now the [[APU]] has sufficient RPMs to provide electrical power through its generator.

With the APU generator | With the [[APU]] generator powered up most of the instruments receive electrical power and now the [[AOA]] indexer lights up and the [[HSI]] (the compass) and ADI (artificial horizon) look much better. | ||
At 85% RPM the APU supplies enough bleed air to start the engines. | At 85% RPM the [[APU]] supplies enough bleed air to start the engines. | ||
