B737 Panic revision
I am in the sim during the next few days; can anyone help with a couple of tech questions for the B737-300 and 500 please.
What does the illumination of an APU BAT OVHT light indicate, obviously a hot battery but is it due to failing exhaust fans or a function of battery charging ? Where are these lights fitted. Forward overhead panel ?
What does the 'Buffet Alert' scratchpad message on the FMC denote, I am supposing a reduced manoeuvre margin but am unable to see this message in any of my FMC notes. The other answer on the question paper describes an upgraded alert called Buffet but I haven't heard of that either.
Lastly, does the ANS alternate nav system have a FDC input or is it solely referenced to the IRSs. I seem to remember that it's just IRS but would be grateful for confirmation.
That's about it, thanks in advance.
