Fuel Run Marker

Recommended Posts

When starting the engines on the v2 747-400X, you would see a magenta line on the EICAS engine management screen which would let you know when to open the fuel run switch during manual startup, approximately at 13.

I don't see how to activate this option on the v3 PMDG so I'm not sure when to open the switch during startup, i've been opening it when it gets to 2.0 but not sure if that's correct.

Can anyone let me know when I should be opening the switch?

When what gets to 2.0, James?

Manual start procedures vary with engine type. What kind of engine are you trying to start? e.g. Rolls Royce engines don't have a magenta line. You have to wait until your N3 reaches 25%  (or as close as possible) before putting the fuel on. Your starter may "run out of steam" and not reach 25% N3.

Hope this helps?

Cheers

Hi John

Sorry, I was typing this from memory at work so I can't remember exactly what I'm looking at for the 2.0.  I will update this query with better info when I can!

Mess around with the autostart setting in your aircraft's equipment options, with the different engine types and have a look.

Sounds like it was probably N1. You should be watching N2 (N3 for RR engines). If you were watching N1 that might be why you didn't see the magenta cue.

Good idea, that way I will see when the fuel kicks in for each.  Nice tip, cheers!
