Thanks A33Zab, excellent reply (as usual!)
Just to confirm I got it right:
- old ADIRU standard uses VS/GS to calculate FPA
- new ADIRU standard uses AoA and pitch/roll only
correct?
Two follow up questions, if you don't mind
- does it mean that the new ADIRU references the FPA to the air, or is it somehow corrected for wind?
- What's inertial altitude? Is that integrated Vzbi?
