Integrated flight and fire control (IFFC) is one such technology. An F-15 has already flown in which the fire-control system, including radar and a electrooptical precision tracking pod, is coupled to the flight controls. The system works by blending pilot commands with automatic inputs generated by the fire-control system while it is locked on to the target. The result is faster tracking and quicker gun kills in air-combat, and accurate air-to-ground weapon delivery in defensive manoeuvres.
The F-15 testbed system is engineered to fine-tune the pilot's coarse tracking manoeuvres. If the target is kept within a box projected on the Hud, graphically representing the authority limits of the IFFC, the system will take out any remaining errors. For automatic bomb release in turns, the pilot follows bank angle and g commands projected on the Hud.
