ATSB Report on C-130 Crash

Thanks to FOR for linking to the ATSB report which made good use of ADS-B and recorder data to estimate airspeed loss. But AoA changes were not included.

Frost’s 1983 paper, Flight in Low-Level Wind Shear commissioned by NASA supplies:



Where: q is the pitch (rate?), the elevated dots are differential over time (equivalent to dt), W is wind in the x and z axes, w indicates wind frame, E earth frame.

What appears to many as an accelerated stall from pilot input may well be a result of gusts. ADS-B and recorder data with video analysis may give a better picture of what happened.
