CONFLICT ALERT
−
A function of certain air traffic
control automated systems designed to alert radar
controllers to existing or pending situations between
tracked targets (known IFR or VFR aircraft) that
require his/her immediate attention/action.
(See MODE C INTRUDER ALERT.)
CONFLICT RESOLUTION
−
The resolution of
potential conflictions between aircraft that are radar
identified and in communication with ATC by
ensuring that radar targets do not touch. Pertinent
traffic advisories shall be issued when this procedure
is applied.
Note: This procedure shall not be provided utilizing
mosaic radar systems.
CONFORMANCE
−
The condition established when
an aircraft’s actual position is within the conformance
region constructed around that aircraft at its position,
according to the trajectory associated with the
aircraft’s Current Plan.
CONFORMANCE REGION
−
A volume, bounded
laterally, vertically, and longitudinally, within which
an aircraft must be at a given time in order to be in
conformance with the Current Plan Trajectory for that
aircraft. At a given time, the conformance region is
determined by the simultaneous application of the
lateral, vertical, and longitudinal conformance
bounds for the aircraft at the position defined by time
and aircraft’s trajectory.
CONSOLAN
−
A low frequency, long-distance
NAVAID used principally for transoceanic naviga-
tions.
CONSOLIDATED WAKE TURBULENCE
(CWT)
−
A version of RECAT that has nine
categories, A through I, that refines the grouping of
aircraft while optimizing wake turbulence separa-
tion.
CONSTRAINT SATISFACTION POINT (CSP)
−
Meter Reference Elements (MREs) that are actively
scheduled by TBFM. Constraint satisfaction occurs
when the Scheduled Time of Arrival generated for
each metered flight conforms to all the scheduling
constraints specified at all the applicable CSPs.
CONTACT
−
a.
Establish communication with (followed by the
name of the facility and, if appropriate, the frequency
to be used).
b.
A flight condition wherein the pilot ascertains
the attitude of his/her aircraft and navigates by visual
reference to the surface.
(See CONTACT APPROACH.)
(See RADAR CONTACT.)
CONTACT APPROACH
−
An approach wherein an
aircraft on an IFR flight plan, having an air traffic
control authorization, operating clear of clouds with
at least 1 mile flight visibility and a reasonable
expectation of continuing to the destination airport in
those conditions, may deviate from the instrument
approach procedure and proceed to the destination
airport by visual reference to the surface. This
approach will only be authorized when requested by
the pilot and the reported ground visibility at the
destination airport is at least 1 statute mile.
(Refer to AIM.)
CONTAMINATED RUNWAY
−
A runway is
considered contaminated whenever standing water,
ice, snow, slush, frost in any form, heavy rubber, or
other substances are present. A runway is contami-
nated with respect to rubber deposits or other
friction-degrading substances when the average
friction value for any 500-foot segment of the runway
within the ALD fails below the recommended
minimum friction level and the average friction value
in the adjacent 500-foot segments falls below the
maintenance planning friction level.
CONTERMINOUS U.S.
−
The 48 adjoining States
and the District of Columbia.
CONTINENTAL UNITED STATES
−
The 49 States
located on the continent of North America and the
District of Columbia
.
CONTINGENCY HAZARD AREA (CHA)
−
Used
by ATC. Areas of airspace that are defined and
distributed in advance of a launch or reentry
operation and are activated in response to a failure.
(See AIRCRAFT HAZARD AREA.)
(See REFINED HAZARD AREA.)
(See TRANSITIONAL HAZARD AREA.)
CONTINUE
−
When used as a control instruction
should be followed by another word or words
clarifying what is expected of the pilot. Example:
“continue taxi,” “continue descent,” “continue
inbound,” etc.
CONTROL AREA [ICAO]
−
A controlled airspace
extending upwards from a specified limit above the
earth.
