If you have a crosswind, you can't maintain a racetrack shape if you
want to do standard rate turns. That is why we double the wind
correction on the outbound. The goal is to make standard rate turns on
both ends of the holding pattern, not to keep the outbound parallel to
the inbound.
Gee...thanks for the explanation Andrew, and to think that for all of
these years, for a one minute pattern, I've been teaching that one
should *triple* the drift on the outbound leg. We taught it that way at
PanAm long before the FAA changed the AIM as follows.
From AIM 5-3-7
(c) Compensate for wind effect primarily by drift correction on the inbound
and outbound legs. When outbound, triple the inbound drift correction to
avoid major turning adjustments; e.g., if correcting left by 8 degrees when
inbound, correct right by 24 degrees when outbound.
