information before you can perform the required duties of an air traffic
controller working at a GCA facility.
CONTROLLER PROCEDURES
1.
a. You are on duty in a GCA facility and monitoring your radar and
radios. Weather is deteriorating. An aviator calls to report that none
of his NAVAID receivers operate. He wants to land at your airport. What
can you do? You can help him land by providing a radar approach to your
airport.
b. Radar approaches, unlike other types of instrument approaches, do
not require extra equipment in the aircraft.
However, to help the
aviator, you must know how to make an ASR approach. An ASR approach is
an instrument approach that an air traffic controller directs based on
the surveillance radar display.
EQUIPMENT CHECKS
2.
a. Provide radar service only with your satisfaction that the radar
presentation and equipment performance are adequate for the service. You
may use military-operated, mobile radar equipment without video map or
map overlay capabilities to conduct surveillance approaches. Instead of
using the video map or map overlay, use either grid lines or the
electronic cursor to form the final approach course.
b. Check the equipment ASAP after you assume responsibility of the
control position. Then check it periodically throughout your watch.
(1) Ensure that the video map or map overlay in use properly aligns
with a permanent target of known range and azimuth on the radar display.
(2) Check one permanent target per quadrant, if possible.
REQUIRED INFORMATION
3.
After setting up radar contact with an aircraft that will conduct a
radar approach, you must furnish the aviator with certain information.
You may omit approach information contained in the automatic terminal
information service (ATIS) broadcast if the aviator states the correct
ATIS broadcast code.
