(MT) A/G HUD pitch ladder not graduated as per NATOPS

[Stickler]

According to the -A and -B NATOPS, the A/G HUD has a vertical FOV of 20° centered on the aircraft symbol (10° up, 10° down). The pitch ladder is graduated every 5° up to 30° pitch up and pitch down, then every 10° thereafter.

In the game, the A/G HUD has an asymmetric FOV of 10° pitch up (note the barely visible 10° mark in the picture immediately below) and approximately 8° pitch down (see the second picture below) with reference to the aircraft symbol, and the pitch ladder is uniformly graduated every 5° (see the third picture down).

Had a look at this and you're right about the pitch ladder, it should not have the 5 degree lines and marks outside of 30 degrees. I know we discussed this at length when implementing it but the fix for this must have got lost or forgotten down the line.

In regards to the HUD FoV however we realised the NATOPS just wasn't correct. The real HUD cam videos we've used as reference show the FoV to be closer to what exists in the current DCS model.

Couldn't resist.

While I cannot rule out that the real HUD was in fact not graduated as per NATOPS, I would like to offer the observation that when superimposing the CCIP and the aircraft symbol using the ELEV LEAD knob in MAN mode, approximately -86 mils are obtained. With the maximum ELEV LEAD setting of -263, the difference is 177 mils. Converting this to degrees: 9.95625°, which very closely matches the NATOPS value of (-)10°.

Why would it be possible to set the manual sight to approximately -10° if the pipper (center dot) already disappears from view at a setting of 223 mils (= 7.7° from the aircraft symbol)? Bad engineering by Grumman?
