Notes:

This is the Pilot’s Display Unit Optical Module which was manufactured by Pilkington (now Qioptic).

The F-16C (single seat) and F-16D (two seat) variants entered production in 1984. The first C/D version was the Block 25 with improved cockpit avionics and radar which added all-weather capability with Beyond Visual Range (BVR) AIM-7 and AIM-120 air-air missiles. Blocks 30/32, 40/42 and 50/52 were later C/D versions. The LANTIRN Diffractive optics HUD was designed for the new aircraft but development was delayed by the complexity of the manufacturing problems. As an interim the Company offered a wide angle conventional optic design.

The HUD PDU has both a raster and a cursive capability with the first application of ‘cursive-in-flyback’ in which the same amount of symbology as in the daytime high brightness mode can be drawn on the CRT using the raster's field flyback period of the Night mode. The system accuracy was enhanced by the ability to apply corrections for the windshield. The optics provides a 25° Total Field of View and a 20° by 15° Instantaneous Field of View which was the maximum that could be achieved within the limitations of the exit lens design and the large distance between the pilot and the HUD, necessitated by the reclined high ‘G’ seat.

The Processor/Symbol Generator in the HUD Electronics Unit (EU) uses the MIL-STD-1553 databus architecture, the MIL-STD-1750 processor and the MIL-STD-1589B Jovial J73 programming language. This was the first time that all three Standards had been used together. The HUD EU has comprehensive video mixing and scan conversion and self-contained weapon aiming capability.

The initial order was placed in 1984 and was valued at nearly $50 million (then about £30 million) to cover both development and production. Over 2300 HUD’s were delivered for the F-16 and the system has been the basis of equipment supplied for other programmes such as for the A-7D/K and F-5 adding another 1500 units to the family. In 1985 the F-16C/D design won the Queen’s Award for Technology Improvements to aircraft Head Up Display systems for the Company.
