Duhhhh?
Can't get a good source describing that FPV for the T7, but isn't it inertial or maybe GPS-aided inertial?
Having had a pitot-static freeze up one day, that sucker was priceless. We lite pukes have had great flight path markers since 1968 or so in the A-7D, F-14, F-15, F-20 prototype, F-22 and F-35.
I think about AF447, and how much a good FPV might have helped.
