Hi,

Very funny (and not too serious, however it works wrong)...

Do this :

- Start APU/GPU

- Do all start procedure, BUT the fuel valve from the overhead. Let them closed.

- Click on Start swith. Open condition lever.  One heard the engine starting, but of course, it wont. Start stops and ignition light stop blinking. Till this, all normal.

- Then just open fuel valve (let the condition lever full open)... and miracle... engine start!

Well funny... but wrong 😉

Cheers

Daniel
