AoA tape may be improperly calibrated

[Stickler]

According to NAVAIR 01-F14AAA-1, 15 May 1995, Change 1 - 1 February 1997, p. 2-155 (and the appropriate pages in other versions of the RL flight manual as well as the Heatblur F-14 manual), the AoA indexer lights come on in certain AoA ranges. In 2.8.0.32235 (did not notice/test before), the AoA tape left of the HUD does not match these ranges.

Indexer	Should come on (units AoA)	Really comes on (units AOA)
Green	16.0 - 30.0	15.0 - 30.0
Green/Yellow	15.5 - 16.0	14.7 - 15.0
Yellow	14.5 - 15.5	13.8 - 14.7
Yellow/Red	14.0 - 14.5	13.1 - 13.8
Red	0.0 - 14.0	0.0 - 13.1

I believe the indexer lights work correctly but the AoA tape is wrongly calibrated since the AoA shown in the F2 view seems to be consistent with the indexer but not with the tape, taking into account the conversion formula of Angle = (Units - 3.715) / 1.089

This is supported by the fact that with the APC on, the aircraft seems to hold 14 instead of 15 units AoA.

Other than making flying precise approaches difficult, this also makes AI LSO grading (both DCS default and Airboss) somewhat unpredictable since both seem to be using actual (not tape-indicated) AoA as a reference.
