BENDIX/KING KR87 AUTOMATIC DIRECTION
FINDER (ADF)
GENERAL
The Bendix/King Digital ADF is a panel-mounted, digitally tuned
automatic direction finder. It is designed to provide continuous 1-kHz
digital tuning in the frequency range of 200-kHz to 1799-kHz and
eliminates the need for mechanical band switching. The system has a
receiver, a built-in electronic timer, a bearing pointer shown on the
G1000 Horizontal Situation Indicator (HSI), and a KA-44B combined
loop and sense antenna. Controls and displays for the Bendix/King
Digital ADF are shown and described in Figure S9-1. The Garmin GMA
1347 Audio Panel is used to control audio output. Audio panel
operation is described in the Garmin G1000 Cockpit Reference Guide.
The Bendix/King Digital ADF can be used for position plotting and
homing procedures, and for aural reception of amplitude modulated
(AM) signals.
The flip-flop frequency display allows switching between preselected
standby and active frequencies by pushing the frequency transfer
button. Both preselected frequencies are stored in a nonvolatile
memory circuit (no battery power required) and displayed in large,
easy-to-read, self-dimming gas discharge numbers. The active
frequency is continuously displayed in the left window, while the right
window will display either the standby frequency or the selected
readout from the built-in electronic timer.
The built-in electronic timer has two timing functions that operate
independently. An automatic flight timer starts when the unit is turned
on. This timer counts up to 59 hours and 59 minutes. An elapsed timer
will count up or down for up to 59 minutes and 59 seconds. When a
preset time interval has been programmed and the countdown reaches
:00, the display will flash for 15 seconds. Because both the flight timer
and elapsed timer operate independently, it is possible to monitor either
one without disrupting the other. The push button controls are internally
lighted. The light intensity is controlled by the AVIONICS dimmer
control knob.
