airspeeds

“Avoid descent rates of 800 fpm feet per minute or greater at airspeeds less than 40 KCAS,” it said, “KCAS” being the abbreviation for “knots-calibrated air speed.”

And so Boyd went back to college, and bootstrapped himself from Fighter Jock to Aeronautical Engineer to try and find a theory that would show exactly at which airspeeds and altitudes enemy planes were superior.

In the meantime, Navair would fly tests with the four remaining prototypes built in the 1990s to establish just how vulnerable the Osprey really was to vortex ring state, to study its handling qualities when landing on a heaving, windy ship deck, and to define its ability to maneuver at low airspeeds.

They repeated the flight profile over and over during those months, taking their measurements at every 500-foot increment of sink rate at a series of ever slower airspeeds.
