To correctly determine the first fix in the flight plan, consultation with the obstacle departure procedure (ODP) is required. Section 2. . Make it part of your departure briefing. There are two types of. IFR aircraft must be assigned an altitude. The purpose of this note is to identify the. Unless specified otherwise, required obstacle clearance for all departures, including diverse, is based on the pilot crossing the departure end of the runway at least 35 feet above the departure end of runway elevation, climbing to 400 feet above the departure end of runway elevation before making the initial turn, and maintaining a minimum climb gradient of 200 feet per nautical mile (FPNM), unless required to … You decide to fly the published Obstacle Departure Procedure (ODP) which requires a ceiling and visibility of 300-1 and says climb on runway heading to 2000. Obstacle Departure Procedures (ODP) are underutilized aviation tools – possibly a result of how unfamiliar and uncomfortable many pilots are with them. Wally: “Obstacle departure procedures or ODPs are one way to depart an airport safely in IMC conditions. The departure clearance included a charted departure procedure that dictated continuing on the runway heading (180 degrees) until intercepting a VOR radial about six miles from the airport. Standard Terminal Arrival (STAR) Charts. 1. References: AIM section 5-2-8. The standard instrument approach procedures and takeoff minimums and obstacle departure procedures (ODPs) are available for examination at the FAA's Rules Docket (AGC-200) and at the National Flight Data Center, 800 Independence Avenue, SW., Washington, DC 20590, or at the National Archives and Records Administration (NARA). EXAMPLE. If an aircraft is vectored off a published Standard Instrument Departure (SID) or Obstacle Departure Procedure (ODP), that vector cancels the DP and ATC becomes responsible for separation from terrain and /or obstructions. 5 − 2 − 8. If there are NO penetrations, the specialist adds a "fudge factor", defined in TERPS, of 48 ft/nm and it is done. Starting with a brief and general overview of two regulatory requirements to set the stage for the purpose of this article include first, Part 25 aircraft certification requires an aircraft 1.b The GOWEN 4 Departure is an obstacle departure procedure (ODP), which is indicated by the word OBSTACLE in the procedure title. If a departing aircraft may turn in any direction from a runway within the […] Obstacle departure procedures will never be assigned by ATC. Departure Procedures. The TERPS specialist uses a Obstacle Identification Surface, which rises at 152 ft/nm from 35 feet above the Departure End of Runway (DER). If obstacles in a departure area require a climb of more than 200 feet per NM be maintained to ensure sufficient terrain separation, the Federal Aviation Administration (FAA) creates an ODP. 6. included in the ATC clearance. Aircraft Performance. IFR takeoff minimums and obstacle departure procedures are prescribed for specific airports/runways and published in either a textual, or graphic form with the label (OBSTACLE) in the procedure title, and documented on an appropriate FAA Form 8260. To alert pilots of their existence, instrument approach procedure charts are annotated with a symbol: Preflight Preparation.

Also, this final rule amends the requirements to facilitate compliance and accurately reflect operating conditions in Obstacle departure procedures (ODP) Obstacle departure procedures (ODP). A preplanned instrument flight rule (IFR) departure procedure printed for pilot use in textual or graphic form to provide obstruction clearance via the least onerous route from the terminal area to the appropriate en route structure. The appearance of the asterisk for a specified runway implies that reference must be made to required published procedures to ensure obstacle and terrain clearance, which may include specified climb gradients, routings, and/or visual climb requirements.6 An example of this is the specified departure procedures for Prince George.7 AIM. CFR 91.177 When should you use one? The AIM 5-2-8 says that pilots must request it: Pilots are responsible to advise ATC as early as possible of the intent to fly the VCOA option prior to departure. It is a common, but mistaken, belief that jets must be able to maintain the specified climb gradient of an ODP or standard instrument departure on one engine. The presence of the ceiling and visibility requirement means that there is an obstacle (or obstacles) that must be avoided visually. We are not told where the obstacle… 5−2−8. . Departure Procedures. The primary purpose is to provide obstacle clearance protection information to pilots; A secondary goal, at busier airports, is to increase efficiency and reduce communications and departure delays through the use of SIDs obstacle avoidance will be indicated with the symbol An ODP that has been developed solely for.
