Spar Valve and Eng Valve On ?

Recommended Posts

After startup the Right engine's ENG Valve Closed and Spar Valve Closed lights stayed on.  I actually didn't notice until I was climbing out and I have a few questions:

 

1) What would cause these lights to say on...yet engine is working fine and fuel flow is normal ?

 

2) If there is a problem then why no warning that would show up on the warning display ?

 

3) I looked at the various manuals to try and find a fix, however, I did not find any.  Based on my reading I tried and inflight re-start of the engine (even though I appeared fine) which ended up clearing the condition.  Is it in the FCOM and I just missed it ?

 

 

thanks.

1.  The lights normally come on dim if the respective valve is closed and bright if the valve is in transit or disagrees with the selected position.  Were the lights bright or dim?

 

2.  None of the blue lights will trigger the master caution light.  Only amber lights outside the normal field of view will trigger the master caution.  Lights on the overhead panels and some of the lights on the fire protection panel are "outside the field of view".  Boeing's definition of that is inconsistent as some of the amber lights on the fire protection panel will trigger the master caution and others will not.

 

3.  I'd say you were dealing with a sim glitch of some kind as there is no failure which would illuminate the engine and spar valve closed lights with the engine still running normally.  I suppose you could have the lights on bright if you put the start lever in cutoff and the valves didn't close but that would require the failure of two different valves which isn't likely.
