Order 7110.65P, Air Traffic Control, with changes

8/5/04Pilot/Controller GlossaryGGATE HOLD PROCEDURES− Procedures at selectedairports to hold aircraft at the gate or otherground location whenever departure delays exceed orare anticipated to exceed 15 minutes. The sequencefor departure will be maintained in accordance withinitial call-up unless modified by flow controlrestrictions. Pilots should monitor the ground control/clearancedelivery frequency for engine start/taxiadvisories or new proposed start/taxi time if the delaychanges.GBT−(See GROUND−BASED TRANSCEIVER.)GCA−(See GROUND CONTROLLED APPROACH.)GDP−(See GROUND DELAY PROGRAM.)GENERAL AVIATION− That portion of civil aviationwhich encompasses all facets of aviation exceptair carriers holding a certificate of public convenienceand necessity from the Civil Aeronautics Board andlarge aircraft commercial operators.(See ICAO term GENERAL AVIATION.)GENERAL AVIATION [ICAO]− All civil aviationoperations other than scheduled air services andnonscheduled air transport operations for remunerationor hire.GEO MAP− The digitized map markings associatedwith the ASR-9 Radar System.GLIDEPATH−(See GLIDESLOPE.)GLIDEPATH [ICAO]− A descent profile determinedfor vertical guidance during a final approach.GLIDEPATH INTERCEPT ALTITUDE−(See GLIDESLOPE INTERCEPT ALTITUDE.)GLIDESLOPE− Provides vertical guidance for aircraftduring approach and landing. The glideslope/glidepath is based on the following:a. Electronic components emitting signals whichprovide vertical guidance by reference to airborneinstruments during instrument approaches such asILS/MLS, orb. Visual ground aids, such as VASI, whichprovide vertical guidance for a VFR approach or forthe visual portion of an instrument approach andlanding.c. PAR. Used by ATC to inform an aircraft makinga PAR approach of its vertical position (elevation)relative to the descent profile.(See ICAO term GLIDEPATH.)GLIDESLOPE INTERCEPT ALTITUDE− Theminimum altitude to intercept the glideslope/path ona precision approach. The intersection of the publishedintercept altitude with the glideslope/path,designated on Government charts by the lightningbolt symbol, is the precision FAF; however, when theapproach chart shows an alternative lower glideslopeintercept altitude, and ATC directs a lower altitude,the resultant lower intercept position is then the FAF.(See FINAL APPROACH FIX.)(See SEGMENTS OF AN INSTRUMENTAPPROACH PROCEDURE.)GLOBAL POSITIONING SYSTEM (GPS)− Aspace-base radio positioning, navigation, and timetransfersystem. The system provides highly accurateposition and velocity information, and precise time,on a continuous global basis, to an unlimited numberof properly equipped users. The system is unaffectedby weather, and provides a worldwide common gridreference system. The GPS concept is predicatedupon accurate and continuous knowledge of thespatial position of each satellite in the system withrespect to time and distance from a transmittingsatellite to the user. The GPS receiver automaticallyselects appropriate signals from the satellites in viewand translates these into three-dimensional position,velocity, and time. System accuracy for civil users isnormally 100 meters horizontally.GO AHEAD− Proceed with your message. Not to beused for any other purpose.GO AROUND− Instructions for a pilot to abandonhis/her approach to landing. Additional instructionsmay follow. Unless otherwise advised by ATC, aVFR aircraft or an aircraft conducting visual approachshould overfly the runway while climbing totraffic pattern altitude and enter the traffic pattern viathe crosswind leg. A pilot on an IFR flight planmaking an instrument approach should execute thePCG G−1
