But my question is how do they do it? The desired track in a hold is not
the pretty little racetrack pattern with two parallel sides and two
semicircles at each end, except in a no-wind situation. The desired track
on the outbound leg is that which will put you in a position from which a
standard rate turn will roll you out on the inbound track That is why we
fly outbound with a multiple of the inbound wind correction.. The GPS box
cannot do that without knowledge of the wind. A fancy FMS which determines
the wind correction from the autopilot can do that, but how can a standalone
GPS box, WAAS or not, do that?



Standard rate turns become irrelevant if they do it right. Keep in
mind, it is standard rate turn or 30 degrees of bank, whichever is less.

So long as Garmin observes the inbound limit (in the case of timing) or
the outbound distance limit in the case of distance, and a pattern is
computed to roll out on course, inbound, they would have a compliant
pattern.
