Up for auction is a Rockwell Collins CTS-451 DME Test Set for testing DME-450/DME-450C/DME-451 aviation systems. This unit allows you to fully test and calibrate various parameters on these distance measuring equipment units.

Key features and specs:

• DME channel selection - choose from up to 126 channels to test
• RNAV mode selection - test lateral navigation functions
• X/Y mode and frequency hold - lock in frequencies for consistent testing
• Selected NAV annunciation - validate indicator lights and alerts

This Collins avionics test set is an excellent tool for any repair shop working on DME systems. The CTS-451 allows you to simulate various signals and conditions to thoroughly evaluate operation and calibration. Very handy portable unit!

This unit is being sold untested and as-is. It shows wear from use including some scuffs and scratches but appears to be in good condition. Instruction manual not included but can be found online.

This is a great opportunity to own a Collins CTS-451 avionics bench test set. Units in any condition are increasingly hard to find, so don't miss out! I will carefully pack for safe shipping.

Please view all photos closely to evaluate condition before bidding. This is an as-is auction for an untested unit - it may require repair work to get in good operating condition. Feel free to send me a message if you have any questions.
