Main functions of the RH150-13
TETRA Remote Control Head

The design of the MMJ, display and controls benefits from Chelton’s extensive experience of fielding TETRA radios for airborne use, which, because of the unique nature of TETRA networks, is significantly more challenging than operating standard tactical radios.

The CDUs display the operating mode and status of the associated radios using a colour screen, with a viewable area of approximately 272 pixels x 204 pixels (48 mm x 67 mm).

The CDUs feature user-upgradeable embedded firmware, which controls the display of text, graphics and icons.

The CDU is compatible with the RH150-13 remote/slave CDUs. The RH150-13 provides an additional control position for larger aircraft.

The
Display

The CDUs are Night Vision Imaging System (NVIS) compliant and may be integrated into NVIS Green B Class A and B cockpits. Light emitted from the displays is LED white. Maximum NVIS radiance is within the MIL-STD-3009 published limits for ‘multi-colour’ electro-optical displays.

For night operation, the keys are backlit with LEDs, the intensity of which is controlled by the aircraft’s bus rail. The key backlighting complies with NVIS Green A.
