The one situation where setting the altimeter to "zero' before flight
makes sense is flying a purely aerobatic flight. You will never be
towed high enough to bust airspace rules. You must be totally focused
on how high you are above the ground and to make sure you do not bust
the 1,500 floor for aerobatic flight. With so much going on in the
cockpit, setting the altimeter to zero makes the scan of the panel
very simple.


I am coming to this thread late , but when I started we set QFE because we

only winch launched to 800ft and timed the flight in minutes and
seconds,you
new where you were going to land and when. Every thing has changed for me
,I now won,t rig if it is not soar able and always fly QNH ,but I still
like QFE
set for the first 3or4minutes till I am sure the rope isn't going to
break.But
then it,s a different world now the LX has QNH and AGL on the screen and
All
you need to do is re-set off tow.It is still nice to have QFE set for your

competition finish and I will re-set especially if control is giving it as
you call
5 minutes.
