Art 2000 Antenna/Receiver/Transmitter; In 182A Color Radar Indicator - Honeywell BENDIX/KING RDR 2000 Installation Manual

BENDIX/KING
The GC 360A Radar Graphics Computer interfaces with Bendix/King RDR 2000 RDS81, 82, 84
or 86 Radar systems. It receives navigation data from a Bendix/King KNS 660, KLN 88, KLN 90,
KLN 90B, KLN 900, or GNS-XLS Long Range Navigation System. A second LNAV, or a Bendix/
King KNR634A, KDM706A or DM441B combination may be added to the system.
The GC 362A TCAS Graphics Processor can be used to interface TCAS with the RDR 2000 sys-
tem.

ART 2000 ANTENNA/RECEIVER/TRANSMITTER

The ART 2000 consists of a radar receiver and a radar transmitter (with applicable antenna) con-
structed as a single unit with a single mounting facility. The RDR 2000 system provides for radar
stabilization input for combined pitch, roll and tilt angles of up to
the antenna stabilization only responds to pitch inputs.
The antenna array is attached to the microwave assembly on the ART 2000 and the two are
moved together as the radar scans. The base of the ART 2000 contains the receiver and all pro-
cessing and control circuits.
The antenna scan angle can be configured for a 90
In EFIS installations with software level 09 or later, the system can be configured with a strut
switch. This configuration puts the system in standby mode when the aircraft is on the ground and
will not allow the ART to transmit unless the override function is enabled.
Upon installation, the system can be configured to include a Target Alert feature. In this configu-
ration, if the ART detects a red intensity target with a minimum size of 2 NM in range and 2
azimuth that is beyond 80 NM and the selected range is 80 NM or less, two red arcs separated by
a black arc are displayed at the top of the display centered on the aircraft heading.

IN 182A COLOR RADAR INDICATOR

The IN 182A Color Radar Indicator provides a five color display (black, green, yellow, red, and
magenta) of weather and a three color display of ground targets within the area scanned by the
radar. Internally generated range marks appear as evenly spaced blue segmented concentric cir-
cles (arcs) on the display to assist in determining range of the targets.
Video display is accomplished by digital techniques, resulting in a continuous bright display of vid-
eo information. The indicator stores a large amount of video information which is read out at rel-
atively high rates (about 60 frames per second). The display continuously updates as the antenna
scans.
The IN 182A has special inputs provided for direct external control of the CRT color guns. This
feature allows an external graphics unit such as a GC 360A or GC 381A or an external remote
graphics unit such as a IU 2023B to control the display. The CC 2024B Checklist Controller can
be used to view a checklist. The IU 2023B and CC 2024B can be used separately or together if
the option for a checklist and NAV graphics is desired.
The indicator mode (Wx, WxA, VP, NAV, or MAP) is selected by push- buttons. The TST mode
is selected by the function switch. Placing the function switch in the TST position causes a pre-
determined test pattern to appear on the indicator. In the TST position the transmitter is not op-
erational. Range and tracking are controlled by pushbutton switches.
A yellow track cursor may be moved either right or left by pressing the track buttons. This assists
in determining azimuth bearing of targets. The cursor moves slowly at about 15
° ° °
1 steps to 45 or 50 left or right, depending on the scan angle configured and the type and soft-
ware level of the indicator). The deviation from the aircraft heading will be indicated in the upper
left corner of the display.
