(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 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. (See INSTRUMENT LANDING SYSTEM.) (See MARKER BEACON.) (Refer to AIM.) OVER-My transmission is ended; I expect a response. OVERHEAD MANEUVER- A series of predeter-mined maneuvers prescribed for aircraft (often in formation) for entry into the visual flight rules (VFR) traffic pattern and to proceed to a landing. An overhead maneuver is not an instrument flight rules (IFR) approach procedure. An aircraft executing an overhead maneuver is considered VFR and the IFR flight plan is cancelled when the aircraft reaches the “initial point” on the initial approach portion of the maneuver. The pattern usually specifies the following: a.. The radio contact required of the pilot. b.. c..
e.. f..The direction of turns. g.. h..
OVERLYING CENTER- The ARTCC facility that is responsible for arrival/departure operations at a specific terminal. P P TIME- |
