ODPs came very close to becoming mandatory for Part 91 in the last
amendment to 91.175 issued last year.


That would require ATC to learn to issue clearances that are consistent with
the ODPs.

Often one will get a clearance that includes something like "...enter
controlled airspace on heading 270..." when the ODP calls for climbing above
the floor of controlled airspace on a very different heading. Recently I
responded by saying that I would turn to 270 upon completion of the Obstacle
Departure Procedure. The controller said "What's that?".

All the back and forth involved in trying to get a clearance that is
consistent with pilot intent is difficult if one has to go through AFSS
Clearance Delivery.
