Use air-to-ground Radio Control at uncontrolled airports or at controlled
airports during periods when the Air Traffic Control tower is closed.  Except
for obstruction lights and the airport beacon, all other lighting systems on
the airport may be operated by air-to-ground Radio Control.

You can directly connect the Radio Controller to the airport lighting systems
or use an interface panel to provide additional switching capabilities or
reduce the load on the Radio Controller.  Configure the Radio Control
system so the runway lights are on whenever the other lighting systems
serving the runway are on, except during daytime operations.

Configure the Radio Control system with a day mode to power only those
lighting systems that are useful during the day.  This mode can be selected
automatically by means of a photocell or by a manual switch.  Using the day
mode, however, means that the daytime IFR procedures associated with the
deactivated lighting systems cannot be used.

In areas with heavy voice traffic on the Radio Controller frequency, there
may be nuisance activation due to random microphone clicks.  If this is a
problem, bypass the three-click setting on the Radio Control for daytime
use.

When the air-to-ground Radio Control is used at night, the lighting system
may not be powered for long periods of time.

During these idle periods, the airport beacon, obstruction lights, and any
other lighting systems that are not radio-controlled continue to operate while
the radio-controlled systems are off.  As an option, leave the runway edge
lights on a low intensity setting, as required by local conditions.  If you
leave on the runway lights during idle periods, also leave on other lighting
systems on a pre-selected intensity.

Table 5 provides guidance on how to interface the Radio Control with the
intensity settings of the airport lighting system.  For example, connect a
lighting system with five intensity settings so three clicks of the microphone
would power brightness setting 1 or 2, five clicks would power setting 3,
and seven clicks would power setting 5.  The airport authority may select
either setting 1 or 2 for the lowest brightness setting, depending on the
background lighting at the airport.
