AlphaJet problem

[Tweek]

Success! I'm not sure exactly what I did, I just flicked a load of switches, but it worked...at least once anyway! I suppose that deserves a thankyou!

But yes, about taxying properly, exactly which bits of the cfg do I edit?

It won't start until you open the throttle to the starting position. You'll know it's open enough when the yellow light comes on on the engine starting panel.

Now you mention it, that sounds amazingly familiar!

BTW You'll also have to change the steering angle in the contact points from 180 to max 80 (60/70 should be fine) otherwise you can only taxi in a straight line

Differential braking challenge (the real BAe Hawk is taxied using diff braking, but I can't remember from by limited Alpha Jet experience whether that has nose wheel steering or not...)

Okey dokey, here's your sequence for starting up/shutting down the Alphajet

1. Click icon 1 (see below) to bring up the throttle and engine startup panels

2. Click icon 2 to bring up the electrics panel

3. Click on either of the small windows 3 to bring up the extended engine startup panel



4. Click on the black/yellow battery switch guard to raise it

5. Switch (click) on the main battery switch and the switches labelled 'g' on the electrics panel (g = gauche = left)



6. Raise (click on) 6 the left engine main switch guard

7. Switch (click) on all the 3 left engine switches

8. Open the throttle 8 slowly just until the left engine ignition light 9 comes on

9. Press (click on) and hold the left engine starter 10 until the engine starts then release. Lower the left engine main switch guard.

10. Repeat for the right engine (switches labelled 'd' - d = droite = right)



To switch off:

Close throttle
Raise the engine main switch guards
Turn main engine switches off
Turn all other engine switches off (engine panel)
Lower engine main switch guards
Switch off engine switches labelled 'g' and 'd' on battery panel and switch off main battery switch
** Can do all of the last step above just by flicking the black/yellow battery switch bar down

Steering angle.

Forget about differential braking. Doesn't work with this baby (try it if you like, but you'll end up disappearing into the scenery  ;) )

To edit steering angle, open up aircraft.cfg file with Wordpad or Notepad, scroll down to Contact_Points section.

Change the number 180 shown in red below to 80 or even a bit less (say 70). Then you'll be able to steer while taxying, but take care because this one accelerates very quickly even at fairly modest power settings.

Let us know how you get on - and especially if you have any problems with any of the above.

Ah, excellent! Now I can switch the engines on and actually know what I'm doing. Makes a change from just clicking buttons and hoping it works! Bravo.

Hey Rollerball - don't mean to discourage ya man; but all them red lines look like a football coach having an epileptic fit!
