Trouble starting engines..

Recommended Posts

Guest CoasterXtreme982

I never had any problem starting the PMDG 747 engines before today. I checked the manual and it says to make sure duct pressure exceeds 30 PSI after engine start selector is pulled. I have done everything like I normally do but this time when I pull the start selector no light comes on. I checked duct pressure and it reads 23. Is this enough to start the engines? if not how can I increase it. I have checked over the entire panel and can't find anything that I was doing wrong. Why is the start switch not lighting up? It will only light up if I send fuel in before pulling the start switch. I thought fuel had to remain cut off until N2 reached that magenta line then you introduce the fuel. I have the APU running with both APU power running. and APU bleed is on. What am I doing wrong?Thank You~Matt Sorce

Matt... If your Autostart switch is selected on, the start valve won't open (i.e. the light won't come on) until you lift your fuel cutoff lever. With Autostart selected, you don't need to wait until your N2 has reached the magental line.... move your fuel control switches straight away. The Autostart system will open the start valve and put the fuel on at the appropriate times (automatically).Deselect Autostart for full manual control of start and fuel valves.Hope this helps.Cheers.Q>
