Components and Characteristics of the Instrument Landing System (ILS)
T-45A UJPT & E2-C2 INav-04
c.
Classification is according to intensity or brightness
(1) High Intensity Runway Lights (HIRLs)
(2) Medium Intensity Runway Lights (MIRLs)
(3) Low Intensity Runway Lights (LIRLs)
HIRLs and MIRLs are variable in intensity, whereas LIRLs
normally have only one intensity setting.
Pilots may request approach control to vary intensity of the
lights to help identify runway when ground lights make it
difficult to pick out. Some airports have lights controlled
from the air by the pilot by keying the VHF radio on a
predetermined frequency

C. Procedure
1.
Controls:
a.
Tune ILS approach frequency on VOR/ILS Control Panel
(1) ILS operates on odd decimal frequencies (108.10 to
111.95)
(2) VOR operates on even frequencies (108.15 to 111.85 and
112.00 to 117.95)
b.
Check COMM/NAV Control Transfer Panel for VOR/ILS
illumination and that NAV, COMM 1, and COMM 2 are selected
