NOTE

The purpose of the DTA intercept is to provide for a manageable

intercept of the holding course. With strong crosswinds, a DTA

intercept may not be sufficient. In this event, use a greater than

DTA intercept, up to 45.

The second time the aircraft crosses the station, commence the no-wind orbit. This orbit is flown

as if there were no wind to compensate for. If this was true, you would:

Roll out of your inbound turn on the holding course.

Take exactly 1 minute to reach the holding fix (for timed holding).

If the above conditions are not met, this indicates there is a wind. Just how far and in what

direction you deviate from these 2 conditions allow you to determine time and heading

correction factors. Applying these factors to a no-wind orbit gives you a correction orbit.

Commence the no-wind orbit as follows:

Direct a standard rate turn. Turn right for standard holding, left for nonstandard holding.

2. Direct the pilot to roll out of the turn on the outbound heading to parallel the holding

course. This heading will be the same as the reciprocal of the holding course.
