PCG G.1 making an instrument approach should execute the published missed approach procedure or proceed as instructed by ATC; e.g., “Go around” (additional instructions if required). (See LOW APPROACH.)(See MISSED APPROACH.)GPD. (See GRAPHIC PLAN DISPLAY.)GPS. (See GLOBAL POSITIONING SYSTEM.)GRAPHIC PLAN DISPLAY (GPD). A view available with URET that provides a graphic display of aircraft, traffic, and notification of predicted conflicts. Graphic routes for Current Plans and Trial Plans are displayed upon controller request. (See USER REQUEST EVALUATION TOOL.)GROUND.BASED TRANSCEIVER (GBT). The ground.based transmitter/receiver (transceiver) re-ceives automatic dependent surveillance.broadcast messages, which are forwarded to an air traffic control facility for processing and display with other radar targets on the plan position indicator (radar display). (See AUTOMATIC DEPENDENT SURVEILLANCE-BROADCAST.)GROUND CLUTTER. A pattern produced on the radar scope by ground returns which may degrade other radar returns in the affected area. The effect of ground clutter is minimized by the use of moving target indicator (MTI) circuits in the radar equipment resulting in a radar presentation which displays only targets which are in motion. (See CLUTTER.)GROUND COMMUNICATION OUTLET (GCO). An unstaffed, remotely controlled, ground/ground communications facility. Pilots at uncontrolled airports may contact ATC and FSS via VHF to a telephone connection to obtain an instrument clearance or close a VFR or IFR flight plan. They may also get an updated weather briefing prior to takeoff. Pilots will use four “key clicks” on the VHF radio to contact the appropriate ATC facility or six “key clicks” to contact the FSS. The GCO system is intended to be used only on the ground. GROUND CONTROLLED APPROACH. A radar approach system operated from the ground by air traffic control personnel transmitting instructions to the pilot by radio. The approach may be conducted with surveillance radar (ASR) only or with both surveillance and precision approach radar (PAR). Usage of the term “GCA” by pilots is discouraged except when referring to a GCA facility. Pilots should specifically request a “PAR” approach when a precision radar approach is desired or request an “ASR” or “surveillance” approach when a nonpreci-sion radar approach is desired. (See RADAR APPROACH.)GROUND DELAY PROGRAM (GDP). A traffic management process administered by the ATCSCC; when aircraft are held on the ground. The purpose of the program is to support the TM mission and limit airborne holding. It is a flexible program and may be implemented in various forms depending upon the needs of the AT system. Ground delay programs provide for equitable assignment of delays to all system users. GROUND SPEED. The speed of an aircraft relative to the surface of the earth. GROUND STOP (GS). The GS is a process that requires aircraft that meet a specific criteria to remain on the ground. The criteria may be airport specific, airspace specific, or equipment specific; for example, all departures to San Francisco, or all departures entering Yorktown sector, or all Category I and II aircraft going to Charlotte. GSs normally occur with little or no warning. GROUND VISIBILITY. (See VISIBILITY.)GS. (See GROUND STOP.)PCG G.2 H HAA. (See HEIGHT ABOVE AIRPORT.)HAL. (See HEIGHT ABOVE LANDING.)HANDOFF. An action taken to transfer the radar identification of an aircraft from one controller to another if the aircraft will enter the receiving controller’s airspace and radio communications with the aircraft will be transferred. HAR. (See HIGH ALTITUDE REDESIGN.)HAT. (See HEIGHT ABOVE TOUCHDOWN.)HAVE NUMBERS. Used by pilots to inform ATC that they have received runway, wind, and altimeter information only. HAZARDOUS INFLIGHT WEATHER ADVISO-RY SERVICE. Continuous recorded hazardous inflight weather forecasts broadcasted to airborne pilots over selected VOR outlets defined as an HIWAS BROADCAST AREA. HAZARDOUS WEATHER INFORMATION. Summary of significant meteorological information (SIGMET/WS), convective significant meteorologi-cal information (convective SIGMET/WST), urgent pilot weather reports (urgent PIREP/UUA), center weather advisories (CWA), airmen’s meteorological information (AIRMET/WA) and any other weather such as isolated thunderstorms that are rapidly developing and increasing in intensity, or low ceilings and visibilities that are becoming wide-spread which is considered significant and are not included in a current hazardous weather advisory. HEAVY (AIRCRAFT). (See AIRCRAFT CLASSES.)HEIGHT ABOVE AIRPORT. The height of the Minimum Descent Altitude above the published airport elevation. This is published in conjunction with circling minimums. (See MINIMUM DESCENT ALTITUDE.)HEIGHT ABOVE LANDING. The height above a designated helicopter landing area used for helicopter instrument approach procedures. (Refer to 14 CFR Part 97.)HEIGHT ABOVE TOUCHDOWN. The height of the Decision Height or Minimum Descent Altitude above the highest runway elevation in the touchdown zone (first 3,000 feet of the runway). HAT is published on instrument approach charts in conjunc-tion with all straight-in minimums. (See DECISION HEIGHT.)(See MINIMUM DESCENT ALTITUDE.)HELICOPTER. Rotorcraft that, for its horizontal motion, depends principally on its engine-driven rotors. (See ICAO term HELICOPTER.)HELICOPTER [ICAO]. A heavier-than-air aircraft supported in flight chiefly by the reactions of the air on one or more power-driven rotors on substantially vertical axes. HELIPAD. A small, designated area, usually with a prepared surface, on a heliport, airport, landing/take-off area, apron/ramp, or movement area used for takeoff, landing, or parking of helicopters. |
