Inner‐transitional OFZ. The inner transitional surface OFZ is a defined volume of airspace along the sides of the runway and inner‐approach OFZ and applies only to precision instrument runways. The inner‐transitional surface OFZ slopes 3 (horizontal) to 1 (vertical) out from the edges of the runway OFZ and inner‐approach OFZ to a height of 150 feet above the established airport elevation.

OBSTRUCTION- Any object/obstacle exceeding the obstruction standards specified by 14 CFR Part 77, Subpart C.
OBSTRUCTION LIGHT- A light or one of a group of lights, usually red or white, frequently mounted on a surface structure or natural terrain to warn pilots of the presence of an obstruction.
OCEANIC AIRSPACE- Airspace over the oceans of the world, considered international airspace, where oceanic separation and procedures per the Interna-tional Civil Aviation Organization are applied. Responsibility for the provisions of air traffic control service in this airspace is delegated to various countries, based generally upon geographic proximi-ty and the availability of the required resources.

OCEANIC DISPLAY AND PLANNING SYS-TEM- An automated digital display system which provides flight data processing, conflict probe, and situation display for oceanic air traffic control.
OCEANIC NAVIGATIONAL ERROR REPORT-A report filed when an aircraft exiting oceanic airspace has been observed by radar to be off course. ONER reporting parameters and procedures are contained in FAAO 7110.82, Monitoring of Navigational Perfor-mance In Oceanic Areas.
OCEANIC PUBLISHED ROUTE- A route estab-lished in international airspace and charted or described in flight information publications, such as Route Charts, DOD Enroute Charts, Chart Supple-ments, NOTAMs, and Track Messages.
OCEANIC TRANSITION ROUTE- An ATS route established for the purpose of transitioning aircraft to/from an organized track system.

(See OBSTACLE DEPARTURE PROCEDURE.)
OFF COURSE- A term used to describe a situation where an aircraft has reported a position fix or is observed on radar at a point not on the ATC‐approved route of flight.
OFF‐ROUTE VECTOR- A vector by ATC which takes an aircraft off a previously assigned route. Altitudes assigned by ATC during such vectors provide required obstacle clearance.
OFFSET PARALLEL RUNWAYS-Staggered runways having centerlines which are parallel.
OFFSHORE/CONTROL AIRSPACE AREA- That portion of airspace between the U.S. 12 NM limit and the oceanic CTA/FIR boundary within which air traffic control is exercised. These areas are established to provide air traffic control services. Offshore/Control Airspace Areas may be classified as either Class A airspace or Class E airspace.
