Part A. EQUIPMENT
1. PRESENTATION AND EQUIPMENT PERFORMANCE
Provide radar service only if you are personally satisfied that radar presentation and equipment
performance are adequate for the service being provided.
a. Alignment Check. As soon as possible after assuming responsibility for a control position, check
the operating equipment for alignment accuracy and display acceptability. Recheck periodically
throughout the watch. Check the alignment of the radar video display by assuring that the video map or
overlay is properly aligned with a permanent target of known range and azimuth on the radar display.
Where possible, check one permanent target per quadrant.
b. Code Monitor. Continuously monitor the Mode 3/A radar beacon codes assigned for use by
aircraft operating within your area of responsibility. This includes the appropriate IFR code actually
assigned and codes 1200 and 1277, as appropriate, unless your area of responsibility includes only
positive controlled airspace. During periods when ring-around or excessive visual flight rule (VFR)
target presentations derogate the separation of IFR traffic, monitoring VFP codes 1200 and 1277 may be
2. SERVICE LIMITATIONS
When radar mapping is not available, limit radar service to separating radar-identified aircraft targets
and vectoring aircraft to intercept a precision approach radar (PAR) final approach course. Provide
limited radar service in areas that ensure no conflict with terrain, traffic on airways, airport control
zones, restricted or prohibited areas, or other ATC areas of jurisdiction. Also provide limited radar
service in areas that ensure no conflict with terrain, traffic on airways, restricted or prohibited areas,
other ATC areas of jurisdiction, or other control zones.
3. ELECTRONIC CURSOR
An electronic cursor may be used to aid in identifying and vectoring an aircraft and to give finer
delineation to a video map. Do NOT use it as a substitute for a video map or map overlay, such as to
form intersections, airway boundaries, and final approach courses. Fixed electronic cursors may be used
