Section 8. Video Maps
FOR RADAR FIX ACCURACY
must be given during commissioning flight checks of a radar to the
accuracy of digital maps, video map plates, or overlays to ensure that the
plate or overlay markings meet specified requirements relative to
permanent targets. In actual practice an aircraft's displayed position can
be slightly in error with respect to its geographic position and still
meet the requirements of FAAO 8200.1, United States Standard Flight
3-8-2. RADAR MAPPING STANDARDS
The minimum radar
mapping capability required for commissioning radar services is one of the
video mapper plus a map overlay.
at USAF installations.
at Navy installations.
Grease pencil markings, plastic tape, compass rose grid lines, range
marks, or other innovations must not be used in lieu of an adequate
digital map, map overlay, or video map.
3-8-3. DISPLAY MAP DATA
To reduce scope
clutter and increase operational efficiency, limit data on display maps to
the following (except for subpara o, facility air traffic managers may
delete items not required):
centerline extension and/or final approach course.
FAAO JO 7110.65, Para 5-9-1, Vectors to Final Approach Course.
emergency landing areas.
(control, special use areas, terminal buffer areas, outer fix holding
pattern airspace areas, no transgression zones, etc.).
use tracks (scramble, recovery, Instrument Departures, etc.).
geographic features (islands, mountains, etc.).
vectoring altitudes in hundreds of feet; e.g., 23-2,300 ft., 100-10,000
o. Airports immediately
outside your area of jurisdiction that are:
airspace used to receive radar handoffs; and
by the facility having jurisdiction over that airspace.
p. For sites
equipped with STARS, facility air traffic managers must specify in a
facility directive procedures for using optional maps.
The intent of subpara o is to assist controllers in making emergency
airport recommendations when inflight emergencies occur near facility
boundaries. There is no intent to establish criteria for airport
depiction. However, insofar as facilities having jurisdiction depict
airports, then those same airports must be depicted on the adjacent
facility's video map.
FAAO JO 7110.65, Para 10-2-15, Emergency Airport Recommendation.
Set the intensity
of the video map and the range marks on the CTRD equipment at the minimum
intensity that will provide the controller with the necessary information.
Supervisory personnel must ensure that a usable intensity is maintained.
3-8-5. COMMON REFERENCE POINTS
traffic managers must ensure the adequacy of common reference points on
radar maps where such points are used in providing air traffic control
services; e.g., handoff points, etc., between adjacent facilities or
between sectors within the facilities using different radar systems.
Whenever possible, simultaneous flight checks should be conducted of these
radar systems. FAAO 8200.1, United States Standard Flight Inspection
Manual, must be used in determining the appropriate tolerances.
