A.
Localizer
1.
Provides azimuth for front and back course approach (unless
antenna shielded from back course)
2.
Usable range: 35 degrees within 10 nm and 10 degrees within
18 nm of course centerline unless published approach depicts a
transition beyond this range
3.
Beam width is 5 degrees wide, 2 1/2 degrees either side of
centerline
4.
Transmits on odd tenths from 108.1 MHz through 111.9 MHz -
Aural Morse code identifier will include the letter “I” preceding
the normal 3-letter identifier
