Start up with GPU

[MicMic]

How is the procedure for an start with GPU? Normally I start the engine and then follow the procedures for the alignment, MFDs, radios, etc... but I wish to know the procedure to be ready for scramble just waiting for the order to start the engine and inmediate deperture. I gess it will be with the engine off and GPU on.

 

Does anyone know where to find this procedure?

Thank you.

The F-16 doesn't have a GPU. It has a pneumatic accumulator (two actually) backing hydraulic pressure to the JFS. The JFS is a fuel-burning device that spins up the main engine via the gearbox. There is only one way to start the F-16 in DCS, via the brake/JFS accumulator(s).

If you just want ground electrical power, then just ask for ground power. Ground electrical power integration is automatic and powers the airplane in the same way the main engine generator does. Right now the TGP doesn't work with ground electrical power (think that's a bug) but everything else is A-OK. I don't know if it's possible to configure the airplane on ground power and then start and fly. It's not done in reality. They either are on a cold jet alert or with engines running. There's no electrical on/engine off alert that I know of. The DTC makes the launch process quite fast if needed. If even those 2 minute response times isn't enough they would run the engine possibly with ground hot refueling as needed.

Looks like the FCR won't turn on on ground power either (might be a bug). Anyway, you can sit on ground power and do almost anything to get ready then start engines and go. I didn't see any issue apart from the FCR/TGP (maybe HTS too didn't test).

AFAIK, the only change for quick scrambles is that the INS is aligned once the jet is parked in its spot on the ramp, so when the pilot jumps into it, the stored heading alignment can be performed. In DCS, this is always possible, so there's no need to do anything else.

This is exactly it. 

F-16s standing alert duty will be started up and a full alignment completed, then they are shut down in place. The aircraft then must not move from that parking location, and a Stored Heading alignment can be completed quickly if the aircraft is scrambled. 

DCS always assumes that a cold aircraft has not been moved since it was last aligned and shut down, so you are essentially always ready to scramble when you hop in a cold jet.

But what you can't do in DCS is fly to another airport, shut the down jet with a cock-on procedure, then fire it back up with a stored heading alignment and continue. And that makes my inner nerd a little sad.

You would have to align the INS on the parking spot where you want to shut down. Than after shutdown and startup you should be able to perform a stored heading alignment.

Unfortunately the simulation does not allow this practice.
