Pilot/Controller Glossary 2/17/05System (ATCRBS). Mode A (military Mode 3) andMode C (altitude reporting) are used in air trafficcontrol.(See INTERROGATOR.)(See RADAR.)(See TRANSPONDER.)(See ICAO term MODE.)(Refer to AIM.)MODE (SSR MODE) [ICAO]− The letter or numberassigned to a specific pulse spacing of the interrogationsignals transmitted by an interrogator. There are4 modes, A, B, C and D specified in Annex 10,corresponding to four different interrogation pulsespacings.MODE C INTRUDER ALERT− A function ofcertain air traffic control automated systems designedto alert radar controllers to existing or pendingsituations between a tracked target (known IFR orVFR aircraft) and an untracked target (unknown IFRor VFR aircraft) that requires immediate attention/action.(See CONFLICT ALERT.)MONITOR− (When used with communication transfer)listen on a specific frequency and stand by forinstructions. Under normal circumstances do notestablish communications.MONITOR ALERT (MA)− A function of the ETMSthat provides traffic management personnel with atool for predicting potential capacity problems inindividual operational sectors. The MA is an indicationthat traffic management personnel need toanalyze a particular sector for actual activity and todetermine the required action(s), if any, needed tocontrol the demand.MONITOR ALERT PARAMETER (MAP)− Thenumber designated for use in monitor alert processingby the ETMS. The MAP is designated for eachoperational sector for increments of 15 minutes.MOVEMENT AREA− The runways, taxiways, andother areas of an airport/heliport which are utilizedfor taxiing/hover taxiing, air taxiing, takeoff, andlanding of aircraft, exclusive of loading ramps andparking areas. At those airports/heliports with atower, specific approval for entry onto the movementarea must be obtained from ATC.(See ICAO term MOVEMENT AREA.)MOVEMENT AREA [ICAO]− That part of anaerodrome to be used for the takeoff, landing andtaxiing of aircraft, consisting of the maneuvering areaand the apron(s).MOVING TARGET INDICATOR− An electronicdevice which will permit radar scope presentationonly from targets which are in motion. A partialremedy for ground clutter.MRA−(See MINIMUM RECEPTION ALTITUDE.)MSA−(See MINIMUM SAFE ALTITUDE.)MSAW−(See MINIMUM SAFE ALTITUDE WARNING.)MTI−(See MOVING TARGET INDICATOR.)MTR−(See MILITARY TRAINING ROUTES.)MULTICOM− A mobile service not open to publiccorrespondence used to provide communicationsessential to conduct the activities being performed byor directed from private aircraft.MULTIPLE RUNWAYS− The utilization of a dedicatedarrival runway(s) for departures and a dedicateddeparture runway(s) for arrivals when feasible toreduce delays and enhance capacity.MVA−(See MINIMUM VECTORING ALTITUDE.)PCG M−6
