    The 1989 FAR requirement was for a windshear radar device which in
those days only told the crew when they were in windshear already and,
obviously, all relevant airlines complied. What Continental did was to
install a later version of windshear radar which, instead of merely telling
you what was doing those nasty things to your plane, gave approximately
30 seconds warning. NASA would like the FAR redrawn so that the predictive
system becomes the standard.  At the time the Black Box (Survival in the
Sky in the US) films were compiled, Continental was the only airline with
these predictive windshear radars installed.
