B757/767 Take off Ref page

[haughtney1]

Heres one for you all you tech gurus....

GPS equipped 757/767 aircraft.
Take off ref page
When you enter a flap/altitude constraint i.e Flap 5/3000, if the FMC is GPS updated, does that constraint give you 3000ft MSL, or 3000ft AGL?
I fly 75's and 76's with different model FMC's, but they all GPS equipped and RNP2.
Look forward to the answers :ok:

Bl:eek::eek:dy Kiwi's,

Mate, it knows the airfield elevation when you put the from bit in the fmc and therefore will be 3000ft above airfield ref. I had this discussion with our old HOT I.P.

Hope you managed to keep your trousers in one piece in BKK

Now that WOULD be an interesting thread!

keep it safe mate :ok:
