PDU HUD Set
In the late 1970s, the USAF laboratories at Wright-Patterson AFB, Ohio, created the Advanced Fighter Technology Integration (AFTI) program office to perform flying demonstrations of advanced technology systems and capabilities for fighter aircraft. F-16A No. 6 was chosen to be the primary flying test bed for the program, and the aircraft was designated AFTI/F-16. An F-16 was chosen because of its modern features, its ease of integrating advanced systems, its low operations and maintenance costs, and the reduced risk of transitioning the technologies to the Air Force's large F-16 fleet.
The aircraft received advanced avionics and cockpit modifications, which were forerunners of those systems in the F-16C/D first produced in 1984. An experimental HUD was one of those modifications. The AFTI PDU had a new larger optical module giving an enhanced field of view of 15deg in azimuth by 20° in elevation with a 25° TFOV. This compares with the original F-16A/B with a 20° circular and an instantaneous FoV of 9° in azimuth by 13.4° in elevation. An extra 1.5° in elevation was accomplished by fitting a very thick combiner which gave the effect of a dual combiner glass. Special coatings on the forward and aft surfaces of the combiner transferred the image between the surfaces with no banding or false horizon. This new glass gave an improved vertical field of view without so much birdstrike risk that the conventional dual combiner construction would have in an aircraft with a one-piece "bubble" canopy. In the event this thick combiner proved unsuccessful and the later F-16C/D reverted to the normal glass. In addition the symbology was much modified in the Electronics Unit to work with the capability that the AFTI now had with its new digital flight control system.
