Problems with Engine spooling up

[Andryl]

Hello everyone,

I haven't flown the mirage for a couple of weeks, but yesterday evening I decided to try again in Nevada skies.

So I followed instructions as per Chuck's guide:

- Done all preflight checks (fly-by-wire settings, auto slats,...)

- Set to ON battery and alternators

- Set ignition/ventilation selector to VENT

- Fire extinguisher set to OFF

- Set low pressure fuel pumps to ON

- Set fuel pump to ON

- Pressed the ignition switch

 

But at this point the engine didn't spool up at all (and, if I remember well, the Engine starting light was alread lit).:(

Has something changed with last update or am I missing something? I'm quite sure that this procedure worked flawlessly last time I flew the Mirage.

 

Thanks in advance

Make sure the throttle on the left has not advanced beyond idle cutoff, if it is slightly forward click on the red button right next to the throttle, sometimes mine starts a bit forward so I tend to check the throttle before anything else.

 

Also note that Chuck's guide is outdated and is only useful for a quick primer I've discovered. Can't blame him really since the aircraft is constantly being updated.

Are you sure the Throttle is in the Idle/off Detent?

 

(And if its not in the Idle Detent click on the Red off button to the Right of the Throttle to bring it back into the detent)

Mmhhh, it could be: I'll check it!

Thanks!

What has changed with the ignition system since january?

Step 15 in the PART 4-START-UP PROCEDURE, is supposed to be the Fuel Cutoff and ought to be closed(cover down) during the start-up. It looks correct in the pictures though so maybe it was just a error in the writing.

 

In step 14 I always put in on D or G and not VENT since the Engine Start sequence in the official manual put's is as "G or D as required".

 

Anyway, I have no idea how valid my steps are compared to how you have written it down, I might just be going about it the wrong way but achieving correct results.

about that VENT, it's actually VENT: OFF/G/D (not VENT/G/D).

 

I confirm that for first part of start up you need to use that red button to make sure throttle is back full

I disagree PiedDroit.

 

VENT (ventilation) ; engine is spooled (a little) but no start plug ignited (and no fuel delivered).

G or D ; select which start plug will be used for ignition (ground start).

 

VENT/G/D is correct.

Ah my bad sorry about that. Thanks for the info. I thought I read something different, it was a while ago.

I never touch the vent switch and never have any trouble starting the Mirage. Battery on, fuel pumps on, open the cover and push the button, works every time.
