Departure Question

The previously cited phrase :
"...ODPs are recommended for obstruction clearance
and may be flown without ATC clearance unless an alternate departure
procedure (SID or radar vector) has been specifically assigned by
ATC. "

is not in my 2008 AIM.
Had it been, I would not have started this thread.


Are you referring to the Jeppesen FAR/AIM? It's in the 2006 edition,
paragraph 5-2-6 INSTRUMENT DEPARTURE PROCEDURES(DP)--OBSTACLE DEPARTURE
PROCEDURES(ODP) AND STANDARD INSTRUMENT DEPARTURES (SID), exactly as you
quote it above. The paragraph in the current AIM has the same title but is
now paragraph 5-2-8.

I'm surprised they don't just assign a name or designator to this type of ODP,
the way they do with SID's, that you can just type into the form.


SIDs are air traffic procedures. ODPs are not, not even graphical ODPs.

This has always been a very weak area in pilot training because the
majority of CFI-Is, DPEs, and FAA FSDO inspectors don't understand it.

The FAA's current (2007) Instrument Procedures Handbook covers it quite
well.

Here's a departure question. (Those who do not fly real airplanes under
IFR need not feel compelled to reply):

I'm departing a non-towered field IFR, let's stay East Coast, and say
Bennington (KDDH), departing eastbound. There is a published departure
proceedure, for obstacle (read mountain) clearance. Under Part 91, I am
not required to follow this proceedure, but due to mountain obscuration I
may wish to do so. What do I put in my flight plan, or in my
communication via the local GCO to indicate whether I intend to return to
the Cambridge VORTAC or not? Albany approach may have other IFR traffic
coming into Bennington, so they will want to know if I am backtracking to
CAM or not.

Thanks in advance . . .

Put in the remarks that you will be flying the KDDH ODP and advise ATC
via the GCO prior to takeoff. Making sure you and ATC are on the same
page makes the system work the best.

Yep. Sounds right to me, after this discussion.
I would still plan to depart KDDH eastbound VFR to avoid wasting 15min in the
DP, if ceilings are 4000 or better (no mountain obscuration). With lower
ceilings (mountain obscuration) like you say makes sense. . .

Thanks to all.
