Engine fails to start if I go to far with starting up the plane

Hi

This is more of a head-scratcher than a genuine problem. I know the best solution - follow the start-up procedure properly - but nevertheless, I'm curious as to why this happens.

If I start up the Harrier and forget to flick the Engine Start switch and just keep on turning things on (MFDs, INS etc.) when I go to start the engine, it won't. I have the APU on, the APU generator, all the fuel flow switches, but flicking the engine start does nothing. At first, I thought that I had used too much voltage from the battery but that doesn't seem to be it as there is often plenty of voltage left when I am trying to start up. I have tried shutting down the things I started up but this still doesn't solve the problem.

Does anyone have a way of recovering from this? Is this something that has been modelled from real life or is it just that the sim can't handle a departure from the prescribed start-up sequence?

I'm really just curious as it would feel more realistic than abandoning the plane and getting a new one.

Cheers!

Interesting. I assume you can do it normally.

I deviate from the procedure, but I just use battery, fuel, DECS, fuel handle. And usually at least 1 mfd on and it starts up fine. (no APU). I think I have managed it with both MFD's and the hud on, maybe radios too.

I don't recall the APU and APU GEN switches being used in the real start-up procedure.

Throttle in off? Sometimes when I forgot to put it in off it won’t start until I move to off.

what arturojgt said. idle cut off behind the throttle, just behind parking brake release

Almost certainly as said the throttle has been nudged forwards early, i have the throttle cut off bound for just this situation.

Open the gate, move the throttle all the way back, and the engine should start spooling after a couple of seconds of engine start being on.

Make sure you close the gate again, otherwise when you move to idel you may shut down your engine in flight!

That sounds reasonable, cheers!

I will give it a go.

Yep. I reckon that was it.

Thanks for the help!

I sometimes get this even if I KNOW I haven't touched the throttle. Part of my pre-start checklist is now verifying the throttle is in the cutoff position

Hi. Some throttles like the TMW have in the cut off position a switch, you need bind that switch to the cut off.

I have experienced logic problems in the startup sequence (see my separate thread) of a similar nature. The only procedure that seems to guarantee a successful engine start every time for me with the Warthog throttle in the physical idle detent is to disengage the wheelbrake until the engine has lit off and then re-engage it (in aft position). If I don’t do this, the sim often fails to recognise initial physical throttle movement on first attempt at startup and this appears to be an unrecoverable situation.

I always before startup make that switch work, remove from the cutoff-idle-cutoff or idle-cutoff. This action is intended to allow the pc recognize the cutoff position is on.

Killing time in the bathroom, honey bring me some matches...fewwwwww.

:thumbup: Same here. I even disengage the Parking Brake, pop off the throttle and make sure that the cut off is in.
