In defense of a HUD or other flight path indication
I can tell you what the AF447 HUD display would have looked like.
- UAS happens. No change in FPV, sucker is on the horizon line and bank angle oscillating.
- Gradual pull up reflected by FPV increasing "x" degrees" above the horizon line and pilot can see exactly how many degrees.
- Inertial vertical velocity decreasing as FPV slowly descends back to horizon line.
- FPV eventually reaches lower limit of the HUD. Meanwhile, pitch attitude remains way up there. Some shuddering from the stall. No spin or violent attitude changes, just a slow right turn until impact.
