Pilot/Controller Glossary 

RADAR FLIGHT FOLLOWING

−

 The observation of the progress of radar

−

identified aircraft, whose primary 

navigation is being provided by the pilot, wherein the controller retains and correlates the aircraft identity with 

the appropriate target or target symbol displayed on the radar scope. 

(See RADAR CONTACT.) 
(See RADAR SERVICE.) 
(Refer to AIM.) 

RADAR IDENTIFICATION

−

 The process of ascertaining that an observed radar target is the radar return from 

a particular aircraft. 

(See RADAR CONTACT.) 
(See RADAR SERVICE.) 

RADAR IDENTIFIED AIRCRAFT

−

 An aircraft, the position of which has been correlated with an observed 

target or symbol on the radar display. 

(See RADAR CONTACT.) 
(See RADAR CONTACT LOST.) 

RADAR MONITORING

−

 

(See RADAR SERVICE.) 

RADAR NAVIGATIONAL GUIDANCE

−

 

(See RADAR SERVICE.) 

RADAR POINT OUT

−

 An action taken by a controller to transfer the radar identification of an aircraft to another 

controller if the aircraft will or may enter the airspace or protected airspace of another controller and radio 

communications will not be transferred. 
RADAR REQUIRED

−

 A term displayed on charts and approach plates and included in FDC NOTAMs to alert 

pilots that segments of either an instrument approach procedure or a route are not navigable because of either 

the absence or unusability of a NAVAID. The pilot can expect to be provided radar navigational guidance while 

transiting segments labeled with this term. 

(See RADAR ROUTE.) 
(See RADAR SERVICE.) 

RADAR ROUTE

−

 A flight path or route over which an aircraft is vectored. Navigational guidance and altitude 

assignments are provided by ATC. 

(See FLIGHT PATH.) 
(See ROUTE.) 

RADAR SEPARATION

−

 

(See RADAR SERVICE.) 

RADAR SERVICE

−

 A term which encompasses one or more of the following services based on the use of radar 

which can be provided by a controller to a pilot of a radar identified aircraft. 

a. 

Radar Monitoring

−

 The radar flight-following of aircraft, whose primary navigation is being performed 

by the pilot, to observe and note deviations from its authorized flight path, airway, or route. When being applied 

specifically to radar monitoring of instrument approaches; i.e., with precision approach radar (PAR) or radar 

monitoring of simultaneous ILS,RNAV and GLS approaches, it includes advice and instructions whenever an 

aircraft nears or exceeds the prescribed PAR safety limit or simultaneous ILS RNAV and GLS no transgression 

zone. 

(See ADDITIONAL SERVICES.) 
(See TRAFFIC ADVISORIES.) 

b. 

Radar Navigational Guidance

−

 

Vectoring aircraft to provide course guidance. 

c. 

Radar Separation

−

 Radar spacing of aircraft in accordance with established minima. 

(See ICAO term RADAR SERVICE.)
