Pilots can fly ODPs without prior clearance unless assigned a standard instrument departure or radar vectored by air traffic controllers. Unlike Standard Instrument Departures, ODPs are generally developed for smaller airports.
ODPs may be designed using either conventional or area navigation (RNAV) criteria. ODPS can be either graphical or textual; graphical ODPs always note "(OBSTACLE)" in the title.
Assessment
When an airport is being analyzed for designing an instrument approach procedure, an obstacle departure procedure assessment is conducted first. If an aircraft can depart at 200ft per nautical mile without running into any obstacles within the assessment area, no ODP will be established. Otherwise, an ODP is included with the instrument procedure. The OPD is developed assuming all aircraft engines are in normal operation.
