Description

Radio Control Restrictions

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.

Interfacing Radio Controller

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.

Intensity Control

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.
