Use of V/S in RVSM
Our Part A tells me that only FLCH (LVL CHG) or VNAV are approved for use in RVSM airspace and that the "use of other modes could introduce further hazards, and therefore be undesireable"
Now this slightly makes sense with the 75/767s, 'cos V/S doesn't have speed protection, but it doesn't make much sense on the 737, which does.
There is also a reference to an AIC 80/2000, which doesn't seem to exist anymore.
Can anyone help me out with this? And does anyone have a newer reference for the AIC?
Many thanks.
