The new standard for Angel Flight (via Angel Flight America) is that it
is only to be used on an actual ANGEL FLIGHT leg, i.e. with a patient or
blood or whatever the mission calls for on board. *ALL* other legs
should be flown under the regular N# callsign. [Some regions may not
have gotten their policies and guidebooks updated yet, much less having
read them.]

It seems as if Amgel Flight West hasn't updated their guidelines yet. The
web page http://www.angelflight.org/call_sign.html still has the old
info.

The page you cite says, "The ANGEL FLIGHT call sign may be used during a
positioning or ferry flight only when the flight is time critical. For
instance, when flying to another airport to pick-up cargo or passengers that
is time critical but not life threatening."
