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. ODAPS. (See OCEANIC DISPLAY AND PLANNING SYSTEM.)ODP. (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. OFT. (See OUTER FIX TIME.)OM. (See OUTER MARKER.)OMEGA. An RNAV system designed for long-range navigation based upon ground-based electronic navigational aid signals. ON COURSE. a.Used to indicate that an aircraft is established on the route centerline. b.Used by ATC to advise a pilot making a radar approach that his/her aircraft is lined up on the final approach course. (See ON-COURSE INDICATION.)ON-COURSE INDICATION. An indication on an instrument, which provides the pilot a visual means of determining that the aircraft is located on the centerline of a given navigational track, or an indication on a radar scope that an aircraft is on a given track. ONE-MINUTE WEATHER. The most recent one minute updated weather broadcast received by a pilot from an uncontrolled airport ASOS/AWOS. ONER. (See OCEANIC NAVIGATIONAL ERROR REPORT.)OPERATIONAL. (See DUE REGARD.)OPERATIONS SPECIFICATIONS [ICAO]. The authorizations, conditions and limitations associated with the air operator certificate and subject to the conditions in the operations manual. OPPOSITE DIRECTION AIRCRAFT. Aircraft are operating in opposite directions when: a.They are following the same track in reciprocal directions; or b.Their tracks are parallel and the aircraft are flying in reciprocal directions; or c.Their tracks intersect at an angle of more than 1350. OPTION APPROACH. An approach requested and conducted by a pilot which will result in either a touch-and-go, missed approach, low approach, stop-and-go, or full stop landing. (See CLEARED FOR THE OPTION.) (Refer to AIM.)ORGANIZED TRACK SYSTEM. A series of ATS routes which are fixed and charted; i.e., CEP, PCG O.2 NOPAC, or flexible and described by NOTAM; i.e., NAT TRACK MESSAGE. OROCA. An off-route altitude which provides obstruction clearance with a 1,000 foot buffer in nonmountainous terrain areas and a 2,000 foot buffer in designated mountainous areas within the United States. This altitude may not provide signal coverage from ground-based navigational aids, air traffic control radar, or communications coverage. OTR. (See OCEANIC TRANSITION ROUTE.)OTS. (See ORGANIZED TRACK SYSTEM.)OUT. The conversation is ended and no response is expected. OUTER AREA (associated with Class C airspace). Nonregulatory airspace surrounding designated Class C airspace airports wherein ATC provides radar vectoring and sequencing on a full-time basis for all IFR and participating VFR aircraft. The service provided in the outer area is called Class C service which includes: IFR/IFR.standard IFR separation; IFR/VFR.traffic advisories and conflict resolution; and VFR/VFR.traffic advisories and, as appropriate, safety alerts. The normal radius will be 20 nautical miles with some variations based on site-specific requirements. The outer area extends outward from the primary Class C airspace airport and extends from the lower limits of radar/radio coverage up to the ceiling of the approach control’s delegated airspace excluding the Class C charted area and other airspace as appropriate. (See CONFLICT RESOLUTION.)(See CONTROLLED AIRSPACE.)OUTER COMPASS LOCATOR. (See COMPASS LOCATOR.)OUTER FIX. A general term used within ATC to describe fixes in the terminal area, other than the final approach fix. Aircraft are normally cleared to these fixes by an Air Route Traffic Control Center or an Approach Control Facility. Aircraft are normally cleared from these fixes to the final approach fix or final approach course. OR Pilot/Controller Glossary OUTER FIX. An adapted fix along the converted route of flight, prior to the meter fix, for which crossing times are calculated and displayed in the metering position list. OUTER FIX ARC. A semicircle, usually about a 50.70 mile radius from a meter fix, usually in high altitude, which is used by CTAS/HOST to calculate outer fix times and determine appropriate sector meter list assignments for aircraft on an established arrival route that will traverse the arc. OUTER FIX TIME. A calculated time to depart the outer fix in order to cross the vertex at the ACLT. The time reflects descent speed adjustments and any applicable delay time that must be absorbed prior to crossing the meter fix. OUTER MARKER. A marker beacon at or near the glideslope intercept altitude of an ILS approach. It is keyed to transmit two dashes per second on a 400 Hz tone, which is received aurally and visually by compatible airborne equipment. The OM is normally located four to seven miles from the runway threshold on the extended centerline of the runway. |
