Figure 6.3. MLS Ground Facility Configurations.
6.7.3.1. NOTE: The USAF also has developed a Mobile Microwave Landing System
(MMLS). MMLS components may be deployed in same configuration as a
conventional MLS or the azimuth, elevation and DME transmitters may be
collocated. MMLS operations are the same as the MLS unless otherwise noted in this
manual or the aircraft tech order.
6.7.4. Approach Azimuth Guidance.
6.7.4.1. Azimuth Guidance. In addition to providing azimuth navigation guidance,
the azimuth station also transmits basic data concerning the operation of the landing
system and advisory data on the performance level of the ground equipment.
6.7.4.2. Azimuth Coverage Area (Figure 6.4). The limits of the azimuth coverage area
are:
6.7.4.2.1. Laterally. Proportional coverage or clearance signal is normally ± 40°
on either side of the runway. Actual coverage should be depicted on the
instrument approach procedure. The coverage volume may be varied to eliminate
multi-path effects caused by terrain or man-made obstructions.
6.7.4.2.2. Elevation. From the horizon (0°) up to an angle of 15° and up to at least
20,000 feet.
6.7.4.2.3. Range. To a distance of at least 20 NM (MMLS range is at least 15
NM).
