I have a further question:- If the FMS was programmed from the holding facility to make a an approach at an airfield, how would it cope with changing from FL to Alt on the altitimeter?

How does the Ground Proximity Warning System know the real distance to the terrain?
GPWS and TCAS are things which pilots are supposed to obey without thinking... wasn´t there a rule that a pilot must obey TCAS even if the ATC is ordering otherwise? Shouldn´t there be a direct connection between TCAS and GPWS with autopilot in that case? Subject to perhaps pilot alerts and possibility of manual overrule - what would you do if your TCAS is ordering climb and the other plane presumably is receiving orders to descend, but what the other pilot does not know is that you have a stall warning, too, against climbing?
