The localizer receiver is tuned when an appropriate localizer frequency is selected on
the nav radio. The localizer receiver outputs the appropriate CDI signal to the flight
system based on where the aircraft is, relative to the center line of the runway. The
localizer receiver also outputs the nav audio signal and automatically decodes the
Morse code identifier from the localizer station.
The glide slope receiver is automatically activated whenever the nav receiver is
tuned to a localizer frequency. The glide slope receiver outputs the appropriate
Glide Slope Indicator (GSI) signal to the flight system based on the aircraft posi-
tion relative to the fixed glide slope of the Instrument Landing System (ILS).
Operating Instructions
NOTE
All ADR-7050 functions are controlled through various Multi-Func-
tion Displays (MFDs). Refer to the AFMS and specific documentation
supplied with your cockpit displays for more detailed instructions.
Power-Up
At power-up, the ADR-7050 performs a power-up self test. The self test ensures
that all major ADR-7050 functions, memory, and microprocessor are operating
properly.
Changing & Swapping Frequencies
To change an active frequency, you must first edit the standby frequency. After edit-
ing the standby frequency, swap the standby frequency with the active frequency.
Once swapped, the standby frequency is immediately and automatically tuned on
the radio and becomes the new active frequency. The former active frequency be-
comes the standby frequency.
