3 JUN 10
ARINC 741 HGA, Side Mount
If a third MCDU is installed, the HSD-440 Mark 2 Terminal cannot use the side-mount
antenna.
The antenna type parameter is in the secure ORT.
To configure the antenna type:
1. In the list of ORT parameters, type the number next to the ANTENNA TYPE
parameter, and then press ENTER.
2. At the prompt, type 2, 4, or 5 and then press ENTER, where:
2—ARINC 781 HGA
4—ARINC 741 HGA, TOP MOUNT
5—ARINC 741 HGA, SIDE MOUNT
The default is set to ARINC 741 HGA, TOP MOUNT.
(2) Configuring the Antenna Mounting Rotation Angle
The antenna mounting rotation angle defines the difference between the fore-aft axis
of the antenna reference plane and the fore-aft axis of the aircraft. The rotation is
measured counter-clockwise from the aircraft forward axis toward the antenna
forward axis (or the port side).
The antenna mounting rotation angle parameter is in the secure ORT.
To configure the antenna mounting rotation angle:
1. In the list of ORT parameters, type the number next to the ANTENNA
MOUNTING ROTATION ANGLE parameter, and then press ENTER.
2. Type a value between 0 and 360, to one decimal place, and then press ENTER.
The default is 0.0.
(3) Configuring the Antenna Mounting Pitch Angle
The antenna mounting pitch angle defines the difference between the fore-aft axis
of the antenna reference plane and the fore-aft axis of the aircraft. The pitch is
measured in the nose-up direction from the aircraft forward axis toward the antenna
forward axis.
The antenna mounting pitch angle parameter is in the secure ORT.
To configure the antenna mounting pitch angle:
1. In the list of ORT parameters, type the number next to the ANTENNA
MOUNTING PITCH ANGLE parameter, and then press ENTER.
2. Type a value between 0 and 360, to one decimal place, and then press ENTER.
The default is 0.0.
(4) Configuring the Antenna Mounting Roll Angle
The antenna mounting roll angle defines the difference between the port-starboard
axis of the antenna reference plane and the port-starboard axis of the aircraft. The
roll is measured in the starboard-up direction from the aircraft starboard axis toward
the antenna starboard axis.
