ODPs are usually depicted in text, not graphic, format and are located in the front of the NACO chart book and on the bottom of the airport information page in Jeppesen’s. What are obstacle departure procedures? “Obstacle departure procedures or ODPs are one way to depart an airport safely in IMC conditions.
What is an obstacle departure procedure?
The fact that an obstacle departure procedure is established means there is something in the way of departing aircraft like maybe a big pile of rocks. Obstacle departure procedures are not mandatory unless of course, it was included with the ATC clearance.
What are the different types of departure procedures?
There are two types of DPs, Obstacle Departure Procedures (ODP), printed either textually or graphically, and Standard Instrument Departures (SID), always printed graphically. All DPs, either textual or graphic may be designed using either conventional or RNAV criteria.
How are departure procedures listed in the IFR?
Textual departure procedures and diverse vector areas are listed by airport in the IFR Takeoff Minimums and (Obstacle) Departure Procedures, Section L, of the Terminal Procedures Publications (TPP) while SIDs and complex obstacle departure procedures will be published graphically in the Instrument Approach Procedure Charts
Are obstacle departure procedures mandatory for Part 91 pilots?
“ It’s true that for Part 91 pilots Obstacle Departure Procedures, or ODPs, are not mandatory. However, when flown correctly, ODPs ensure terrain and obstacle clearance. That alone is a strong argument for using them whenever terrain and obstacles can’t be comfortably avoided visually.
Where can I find ODP in ForeFlight?
Fortunately, Foreflight and most of the other electronic flight planning tools list the ODPs under the Procedures tab of the airport. Click on Departures and then Takeoff Minimums. You still have to scroll through several pages of text to find the procedure if it is not a named graphic procedure.
Does every airport have an ODP?
Obstacle departure procedures are not mandatory unless of course, it was included with the ATC clearance. Typically the ATC clearance will not include the ODP unless the controller assigns it for separation. It is the pilot's responsibility to avoid obstacles until at or above the minimum vectoring altitude.
What are departure procedures?
Departure Procedures are pre-planned terminal instrument flight rule (IFR) procedures, designed for two reasons: The primary purpose is to provide obstacle clearance protection information to pilots.
Where are takeoff minimums published?
If you use ForeFlight, look under the "Procedures - Departure" tab on the airport description page and click on "Takeoff Minimums." Non-standard minimums are published when there are obstacle departure procedures to ensure you maintain safe clearance.

Which clearance procedures may be issued by ATC?
ATC clearances normally contain the following:Clearance Limit. The traffic clearance issued prior to departure will normally authorize flight to the airport of intended landing. ... Departure Procedure. ... Route of Flight. ... Altitude Data. ... Holding Instructions.
How are departure procedures named?
Standard instrument departure (SID) routes, also known as departure procedures (DP), are published flight procedures followed by aircraft on an IFR flight plan immediately after takeoff from an airport.
Which procedure applies to instrument departure procedures?
Which procedure applies to instrument departure procedures? If an instrument departure procedure is accepted, the pilot must possess a textual or graphic description.
What is a Part 91?
Part 91 is the section of the Federal Aviation Regulations that provides general operating and flight rules for civil aircraft. Whether you're flying a Cessna 182 or a Boeing 777, you have to comply with these rules.
What are FAA standard takeoff minimums?
Standard takeoff minima are one statute mile for aircraft having two engines or less and one-half statute mile for aircraft having more than two engines. Specified ceiling and visibility minima will allow visual avoidance of obstacles during the initial climb at the standard climb gradient.
What is a SID in aviation?
A Standard Instrument Departure Route (SID) is a standard ATS route identified in an instrument departure procedure by which aircraft should proceed from take-off phase to the en-route phase.
How to tell ATC you're flying an ODP?
It's always best to tell ATC you're flying the ODP by putting it in the remarks of your flight plan from a non-towered airport. If there's a tower, you could could still notify Tower you wish to fly the ODP and you could get a clearance to do so. But that would be more for practice or where you couldn't meet a non-standard climb requirement published for the diverse vector area. That's a pretty rare situation.
What should pilots notify ATC of?
(I guess this assumes you have more than one engine.) Pilots should notify ATC as soon as possible of reduced climb capability in that circumstance.
What is the role of pilots in the VCOA?
Pilots are responsible to advise ATC as early as possible of the intent to fly the VCOA option prior to departure. These textual procedures are published in the ‘Take−Off Minimums and (Obstacle) Departure Procedures’ section of the Terminal Procedures Publications and/or appear as an option on a Graphic ODP. see more.
How far do you have to be to fly ODP?
If you're getting specific departure instructions as part of your clearance or from a Tower controller before departure, you simply fly those instructions. Like the ODP, those instructions commence after you're 400 feet AGL unless specified otherwise, and assume 200 feet per NM, unless specified otherwise (non-standard diverse vector area or on a published procedure included in your clearance).
What is it called when an aircraft turns in any direction?
If a departing aircraft may turn in any direction from a runway within the limits of the assessment area and remain clear of obstacles, that runway passes what is called a diverse departure assessment and no obstacle departure procedure is established. The fact that an obstacle departure procedure is established means there is something in ...
What is the Aeronautical Information Manual?
The Aeronautical Information Manual spells out best practices for pilots. Here is what it says about departure procedures.
Is obstacle departure mandatory?
Obstacle departure procedures are not mandatory unless of course , it was included with the AT C clearance. Typically the ATC clearance will not include the ODP unless the controller assigns it for separation. It is the pilot’s responsibility to avoid obstacles until at or above the minimum vectoring altitude.
Who is responsible for obstacle clearance?
Beyond this distance, the pilot is responsible for obstacle clearance if not operating on a published route, if below (having not reached) the MEA or MOCA of a published route, or an ATC assigned altitude
When does the segment of the procedure that requires the pilot to see and avoid obstacles end?
That segment of the procedure that requires the pilot to see and avoid obstacles ends when the aircraft crosses the specified point at the required altitude
How far can an ODP be?
ODPs are normally designed to terminate within these distance limitations, however, some ODPs will contain routes that may exceed 25/46 NM; these routes will ensure obstacle protection until reaching the end of the ODP
What is standard instrument departure?
Standard Instrument Departures are air traffic control (ATC) procedures printed for pilot/controller use in graphic form to provide obstruction clearance and a transition from the terminal area to the appropriate en route structure
When is a climb gradient required?
Compliance with a climb gradient for these purposes is mandatory when the procedure is part of the ATC clearance, unless increased takeoff minimums are provided and weather conditions allow compliance with these minimums
How far above the DER is the climb gradient?
The standard required obstacle clearance (ROC) of 48 feet per NM to clear these obstacles would require a climb gradient greater than 200 feet per NM for a very short distance, only until the aircraft was 200 feet above the DER
How high above the departure end of runway elevation is the turn?
If an initial turn higher than 400 feet above the departure end of runway elevation is specified in the DP, the turn should be commenced at the higher altitude
What are the two types of departure procedures?
There are two types of Departure Procedures – Obstacle Departure Procedures or ODPs and Standard Instrument Departures – the more common SID. Obstacle Departure Procedures are pre-planned IFR procedures which provide obstruction clearance from the terminal area to the appropriate enroute structure. ODPs are recommended for obstruction clearance ...
Where are ODPs in Foreflight?
If using ForeFlight, ODPs from the Terminal Procedures Publication are found in the "Procedures" tab under "Departures."
When departing a Class G airport, should you assume that your clearance accounts for obstacles?
When departing a Class G (non-towered) airport, you shouldn’t assume that your clearance accounts for obstacles. ODPs are rarely assigned by ATC. A clearance direct to the first fix on the flight plan doesn’t imply that the path is clear. It’s up to you to use the ODP if necessary to keep from hitting anything.
Where is ODP in airport?
The ODP will be in the procedures area of the software if they are graphical. The textual version will be in the Airport/Facilities guide only, so it too must be checked.
Is ODP safe on a runway?
The minimums apply to the ODP, so the ODP for a runway is predicated upon compliance with the T/O minima for that runway, and is not guaranteed to be safe unless the minima (especially climb gradient) are met.
Do VFR pilots know what ODP is?
Great words of wisdom for IFR rated pilots, but most VFR pilots may not even know what the ODP is and how to get a copy for airports. I show my student pilots an IFR low book at least once during the time we do their required 3 hours of instrument familiarization, but that is the last time they probably will ever see them until they do IFR training later in their flying career.
