Obstacle Departure Procedure and compliance.

Asked by: 920 views Airspace, Commercial Pilot, FAA Regulations, Flight Instructor, General Aviation, Instrument Rating

Hello everyone,

I have been going though the IAP and found out couple of questions regarding the ODP procedure listed in the approach plate.

In the beginning of the approach plate, they list the TO Min and ODP for specific airport and I am pasting one of them below for your reference.

KDED

TAKEOFF MINIMUMS AND (OBSTACLE) DEPARTURE PROCEDURES AMDT 3 06159 (FAA) DEPARTURE PROCEDURE: Rwy 5, climb via heading 054° to 1800 before proceeding on course. Rwy 12, climb via heading 122° to 1800 before proceeding on course. Rwy 23, climb via heading 234° to 1800 before proceeding on course. Rwy 30, climb via heading 302° to 1800 before proceeding on course.

NOTE: Rwy 5, numerous trees beginning 64' from DER, 245' left of centerline, up to 100' AGL/143' MSL. Numerous trees beginning 869' from DER, 410' right of centerline, up to 100' AGL/154' MSL. Rwy 12, numerous trees beginning 154' from DER, 129' left of centerline, up to 100' AGL/153' MSL......

My question here was that, in a IFR or VFR condition, do we have to comply with the ODP route/procedure and inform the ATC that we are flying the ODP? or does ATC expect us to fly the route?

Secondly, there were airports without the departure procedure but NOTE section containing some of the obstacles around the airport in distance and their height. Is this for alerting pilots and letting us aware of obstacles ?

Lastly, there was another note I got stuck with :

CIVIL USERS NOTE: Title 14 Code of Federal Regulations Part 91 prescribes standard takeoff rules and establishes takeoff minimums for certain operators as follows: (1) Aircraft having two engines or less - one statute mile. (2) Aircraft having more than two engines - one-half statute mile. These standard minima apply in the absence of any different minima listed below.

As far as I know, operation under part91 does not have prescribed minimum prescribed visibility for takeoff and the note above and my understanding of part91 operation both conflicted and need explanation on this !

    Most part 91 operators do not need to follow an ODP, but would be wise to do so. If the ODP is graphical and included in your clearance, then you must fly it. If the ODP is a VCOA (Visual Climb Over Airport), you may choose to fly it, but must advise ATC prior to departure that you will be flying it. A SID includes any required obstacle departure and you do not fly the ODP followed by the SID. A SID is part of a clearance and must be flown if you accept the clearance. In general, if one of the above exceptions does not apply, the pilot may choose to fly the ODP prior to continuing on the route without notifying ATC. It is expected you will do so, but you are not required to. An ODP or DP is a means of avoiding obstacles and getting to the assigned route, but is not necessarily the only means. Certificated operators have no choice and must fly the ODP or DP.

    The close in obstacles are provided for pilots information to help evaluate how they would clear the obstacles, particularly in the event of an engine failure in a multi engine aircraft.

    Part 91 Subpart K operators need to comply with the departure minimums, other part 91 operators don’t. So some do and most don’t.
