situations between a tracked target (known IFR or
VFR aircraft) and an untracked target (unknown IFR
or VFR aircraft) that requires immediate attention/
action.

(See CONFLICT ALERT.)

MONITOR- (When used with communication

transfer) listen on a specific frequency and stand by
for instructions. Under normal circumstances do not
establish communications.

MONITOR ALERT (MA)- A function of the TFMS
that provides traffic management personnel with a
tool for predicting potential capacity problems in

individual operational sectors. The MA is an
indication that traffic management personnel need to
analyze a particular sector for actual activity and to
determine the required action(s), if any, needed to
control the demand.
MONITOR ALERT PARAMETER (MAP)- The
number designated for use in monitor alert
processing by the TFMS. The MAP is designated for
each operational sector for increments of 15 minutes.

MOSAIC/MULTI-SENSOR MODE- Accepts posi-
tional data from multiple radar or ADS-B sites.
Targets are displayed from a single source within a
radar sort box according to the hierarchy of the
sources assigned.


MOVEMENT AREA- The runways, taxiways, and

other areas of an airport/heliport which are utilized

for taxiing/hover taxiing, air taxiing, takeoff, and
landing of aircraft, exclusive of loading ramps and
parking areas. At those airports/heliports with a

tower, specific approval for entry onto the movement
area must be obtained from ATC.
(See ICAO term MOVEMENT AREA.)

MOVEMENT AREA [ICAO]- That part of an
aerodrome to be used for the takeoff, landing and
taxiing of aircraft, consisting of the maneuvering area

and the apron(s).

MOVING TARGET INDICATOR- An electronic
device which will permit radar scope presentation
only from targets which are in motion. A partial
remedy for ground clutter.

MULTICOM- A mobile service not open to public
correspondence used to provide communications

or directed from private aircraft.

MULTIPLE RUNWAYS- The utilization of a
dedicated arrival runway(s) for departures and a

dedicated departure runway(s) for arrivals when

feasible to reduce delays and enhance capacity.
