Air to ground Radio Control

Application

The RC 311 radio-controller allows the remote control of any connected equipment, by means of a coded radio signal, consisting in a sequence of carrier pulses. It mainly consists of an amplitude modulation radio receiver and an activation circuit, and it operates at a fixed frequency, into the 118_136 MHz band, to be set before delivery. The RC 311 radio-controller complies with the FAA specifications L-854 (as in the Advisory CIRCULAR ac 150/5345-49) FOR TYPE I AM receiver and style A decoder and therefore it is suitable to be used to switch on the aerodrome’s lights, which is the more frequent use of this apparatus. The RC 311 radio-control drives the automatic switching-off of the lights 15 minutes after the reception of the last activating signal.
