Northrop Grumman has joined forces with Elbit Systems to offer a new terrain-following/terrain-avoidance (TF/TA) system for use with Lockheed Martin's C-130 tactical transport.

Already selected for integration with the Hercules as part of an ongoing avionics upgrade programme for an undisclosed operator, the system combines Northrop's APN-241 radar with Elbit head-up displays. Using a digital terrain elevation database and the terrain-following radar as an active sensor, it will enable pilots to fly and manoeuvre safely at low level in all weather conditions, by day or night.

A demonstrator of the TF/TA HUD demonstrator is expected to fly within the coming year using an international customer's C-130.

The APN-241 is the standard radar for Lockheed's new-generation C-130J and Alenia Aermacchi's C-27J Spartan, and has also been installed in the Airbus Military C295.
