Precision Approach Landing System (PALS). The PALS is an
unattended, self-contained radar system. The PALS detects azimuth, elevation,
information of aircraft on final approach to PALS instrumented
runways. This information is displayed in the Military Terminal Radar
Approach Control Facility (MTRACON). See Facility Plate 134-40 (Sheets 1
through 4 of 4).
Precision Approach Radar (PAR). The PAR is an unattended
self-contained radar system. The PAR detects azimuth, elevation, and range
information of aircraft on final landing approach to PAR instrumented runways.
This information is displayed in the MTRACON. The PAR can be mounted on a
fixed base or on a turntable. See Facility Plate 134-40 (Sheets 1 through 8
Location. Locate PALS and PAR sites adjacent to the instrumented
runway or runway intersection. Refer to NAVELEX 0101,107; Naval Shore
Structure. The PALS and PAR systems are housed in a transportable
shelter provided by the system manufacturer. Provide the following:
Reinforced concrete foundations for PALS antenna tower.
Reinforced concrete platform for the fixed mounted PAR.
Reinforced concrete foundations to support the turntable mounted
Provide concrete anchor blocks for turntable stop anchors bolts.
and control cables at a point 1,000 feet from the radar set. Ensure
electrical systems do not interfere with radio and radar transmissions.
