TRA - 45A Terrain Display and Radio Altitude Indicator

The Honeywell TRA 45A combines terrain display and radio altitude information into a single, space-saving multifunction instrument. The TRA 45A is designed to work with Honeywell's enhanced ground proximity warning systems (EGPWS). Its lightweight and small size conserves scarce instrument panel space. The display is a color active-matrix liquid crystal display (AMLCD).

The TRA 45A combines both terrain display and radio altitude information into a single, 3.26" x 3.26" space-saving multi-function instrument. Designed to work with the Honeywell Enhanced Ground Proximity Warning Systems, the TRA 45A will also display radio altitude data from a wide variety of radio altimeter systems.

Weighing in at only three pounds, this easy-to-operate unit can replace your present radio altitude indicator, thus conserving scarce instrument panel space.

Designed for easy operation
The front panel has been carefully designed for easy use of the three control keys, the brightness control knob and the ambient light sensor.

Use the Up and Down keys to change the display range from 5NM to 320NM in discrete steps - 5, 10, 20, 40, 80, 160, 320NM. The Up and Down keys can also be used in conjunction with the Mode key to control the setting of the Radio Altimeter Decision Height Annunciator.

Use the Brightness Control Knob and the Ambient Light Sensor to control the display backlight brightness. You can also use an external dimming bus (0-5 VAC/VDC or 0-28 VDC) in place of the Brightness Control Knob. A Remote Light Sensor input is also included for use with industry-standard Remote Light Sensors.
