For what it's worth. Approach "units" were used as early as the mid 1950s in
the North American FJ-3.

Made it easier to trap between the sails on the original Constitution.

Elsewhere I've read that the Tomcat flies "units" of AoA, not degrees,
with its AoA range of -10 to +40 degrees being converted to units in the 0
to +30 range. That would mean the formula for converting units to degrees
in that plane is [UnitsAoA = .6 * DegreesAoA + 6]. I've also read that
approach AoA for the F-14 is 15 units, which would be... 15 degrees! Holy
crap. Is that correct? That seems awfully high (too far nose up) to me,
especially given the Hornet's ideal 8.1degrees. Can anyone confirm or
correct these values? Or is there something weird going on with wing angle
of incidence (or something else) that throws a spoke in my assumption that
15 degrees AoA means 12 degrees nose up on approach. (15, minus 3 for the
glideslope.) Any help appreciated. Thanks!
