Flight Line Test Sets

Also referred to as avionics test equipment, flight line test sets support ADS-B (Automatic Dependent Surveillance-Broadcast) performance testing, utilizing air traffic technology and minimizing reliance on ground-based radar. This equipment can improve the overall safety of air traffic control. 

What is ADS-B?

The purpose of avionics test equipment is for testing protocols, such as ADS-B transponders, to verify ATC's capability of receiving, decoding, and displaying messages from the flight line, in accordance to DO-260A/B. The ADS-B standard was established by the FAA in 2020 for aircraft flying within controlled airspace in the U.S., requiring aircraft to include a positioning source as part of their avionics. This standard applies to airlines, private jets, helicopters, turboprops, and ADS-B transponders.

Flight Line Test Sets Functions

Conducting flight line testing can achieve greater efficiency and improvement in optimizing aircraft spacing, direct routing, and situational awareness for air traffic controllers and pilots. General procedures identify the controls, connectors, indicators, and display screens used in individual test modes.
