Gotta go along with Dave. Don't fall into the trap of flying outbound a
certain number of minutes...the changing wind makes that a poor choice. Go
out until you are beneath the glideslope and, as Dave says, far enough so
that you have time to get squared away (and get a handle on the wind at PT
altitude...which is a clue, but not the answer, to the wind going downhill).


By now every serious instrument pilot should have GPS on-board. If not an IFR
unit, then at least a good hand-held. With that a consistant *distance* from
the PT fix outbound at which to begin the turn brings it all into the 21st
Century.

And, of course, RNAV(GPS) procedures themselves never have a procedure turn. If
a course-reversal initial approach segment is required in the design, it will
always be a holding pattern reversal.

With the proper use of modern avionics timing of any phase of an instrument
procedure should be a thing of the past.
