I've noticed that when the main tanks pumps are off and the lights on, pressing the Master Caution light does not turn it out or extinguish the Fuel light on the six-pack.  As far as I can remember (I've got 2100 hours on the real 737-200) it should at least reset the Master caution light.  Also, when you do the fire test, the fire warning light does not illuminate as it should.  Just wondering if these are anomolies due to some limitations of FS9?

 

The lights will (also) stay on if the associated tank is empty.

 

Anyway, it's proabably just shortcut gauge programming. Nothing to worry about.

In the initial post I meant to say the red Master Warning Light, not the fire warning light.  The Master Warning light doesn't appear to work at all.  Bjoern, when the center tank is empty and the pumps off, the low pressure lights are out.

Well, maybe it's a bug. Don't worry about it.
