Head Up Display

This is the most common HUD found in the F-16s (WAC HUD)

The Head-Up Display (HUD) is a semi-transparent screen positioned directly in front of the pilot’s line of sight. It projects critical flight data, such as altitude, speed, heading, pitch, and roll, onto the windshield, allowing the pilot to access essential information without diverting attention from the forward view. The display also integrates navigation data and weapon status information. Pilots can customize the information shown on the HUD using the HUD Control Panel. HUD is a part of Up-Front Control (UFC) along with Integrated Control Panel (ICP) and Data Entry Display (DED).
Remember, the WAC HUD and WAR HUD have the same HUD layout, the only difference is the IFOV and FOV.

FOV	Degrees
IFOV (Instantaneous Field Of View)	20x15
TFOV (True Field Of View)	25x25

WAC HUD is mostly used on Block 25, 30/32 50/52/52.

FOV	Degrees
IFOV (Instantaneous Field Of View)	30x17
TFOV (True Field Of View)	20x30

WAR HUD is mostly used on Block 40/42, F-16D Block 52+ RSAF.

Nav Mode HUD layout

Element	Information
Roll Indicator	The roll angle of the aircraft (Symbol marked every one degree). Only show when DED/PFLD DATA Switch is in the off position.
Magnetic Heading	The magnetic heading of the aircraft (Symbol marked every five degrees). Only show when Vertical Velocity Scale (VV/VAH) Switch is in VV/VAH or VAH position.
Selected Steerpoint / Distance	Show the distance in Nautical Miles from the aircraft to the selected steerpoint. Three digits for distance and Two digits for steerpoint. e.g. 001>01, 014>13.
Time To Steerpoint	Time to the steerpoint selected.
Slant Range	Show the direct, line-of-sight distance between the aircraft and a target or object in Nautical Miles. B - range computed by barometric altitude and sighting point elevation D - range computed by DTS F - range computed by FCR R - range computed by CARA (Symbol Range computed + Four digits for distance). e.g. B015.3, B055.2, D024.1. XXX if nothing is selected
Altitude Low Setting (AL)	Show the selected altitude low value in feet. B - range computed by barometric altitude and sighting point elevation. "AL" + Significant digits of the value. e.g. AL 200, AL 600, AL 10000.
Radar Altitude (AR)	Show the radar altitude in feet. "AR" + Significant digits of the value. e.g. AR 20, AR 15460, AR 24520.
