8/5/04Pilot/Controller Glossarynonmountainous terrain areas and a 2,000 foot bufferin designated mountainous areas within the UnitedStates. This altitude may not provide signal coveragefrom ground-based navigational aids, air trafficcontrol radar, or communications coverage.OTR−(See OCEANIC TRANSITION ROUTE.)OTS−(See ORGANIZED TRACK SYSTEM.)OUT− The conversation is ended and no response isexpected.OUTER AREA (associated with Class C airspace)−Nonregulatory airspace surrounding designatedClass C airspace airports wherein ATC provides radarvectoring and sequencing on a full-time basis for allIFR and participating VFR aircraft. The serviceprovided in the outer area is called Class C servicewhich 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 nauticalmiles with some variations based on site-specificrequirements. The outer area extends outward fromthe primary Class C airspace airport and extends fromthe lower limits of radar/radio coverage up to theceiling of the approach control’s delegated airspaceexcluding the Class C charted area and other airspaceas appropriate.(See CONFLICT RESOLUTION.)(See CONTROLLED AIRSPACE.)OUTER COMPASS LOCATOR−(See COMPASS LOCATOR.)OUTER FIX− A general term used within ATC todescribe fixes in the terminal area, other than the finalapproach fix. Aircraft are normally cleared to thesefixes by an Air Route Traffic Control Center or anApproach Control Facility. Aircraft are normallycleared from these fixes to the final approach fix orfinal approach course.OROUTER FIX− An adapted fix along the convertedroute of flight, prior to the meter fix, for whichcrossing times are calculated and displayed in themetering position list.OUTER FIX ARC− A semicircle, usually about a50−70 mile radius from a meter fix, usually in highaltitude, which is used by CTAS/HOST to calculateouter fix times and determine appropriate sectormeter list assignments for aircraft on an establishedarrival route that will traverse the arc.OUTER FIX TIME− A calculated time to depart theouter fix in order to cross the vertex at the ACLT. Thetime reflects descent speed adjustments and anyapplicable delay time that must be absorbed prior tocrossing the meter fix.OUTER MARKER− A marker beacon at or near theglideslope intercept altitude of an ILS approach. It iskeyed to transmit two dashes per second on a 400 Hztone, which is received aurally and visually bycompatible airborne equipment. The OM is normallylocated four to seven miles from the runway thresholdon the extended centerline of the runway.(See INSTRUMENT LANDING SYSTEM.)(See MARKER BEACON.)(Refer to AIM.)OVER− My transmission is ended; I expect aresponse.OVERHEAD MANEUVER− A series of predeterminedmaneuvers prescribed for aircraft (often information) for entry into the visual flight rules (VFR)traffic pattern and to proceed to a landing. Anoverhead maneuver is not an instrument flight rules(IFR) approach procedure. An aircraft executing anoverhead maneuver is considered VFR and the IFRflight plan is cancelled when the aircraft reaches the“initial point” on the initial approach portion of themaneuver. The pattern usually specifies the following:a. The radio contact required of the pilot.b. The speed to be maintained.c. An initial approach 3 to 5 miles in length.d. An elliptical pattern consisting of two 180degree turns.e. A break point at which the first 180 degree turnis started.f. The direction of turns.g. Altitude (at least 500 feet above the conventionalpattern).h. A “Roll-out” on final approach not less than 1/4mile from the landing threshold and not less than 300feet above the ground.PCG O−3
