L3Harris will deliver tools including GH-4001 Electronic Standby Instrument System (ESIS) and Tactical Airborne Navigation Systems (TACAN+).

The two systems will enable pilots to efficiently achieve mission-critical responsibilities via improved situational awareness and advanced flight data to enhance safety.

L3Harris’ TACAN+ system features two automatic air-to-air transmit and receive modes, which provide improved tactical efficiency and mission capabilities to the aircraft.

In addition, the system will allow the aircraft to track another lead aircraft in a variety of flying operations, with a minimum closest follower distance of 20m.
