Sounds like a serious design flaw if g-suit inflation can obstruct the control column....
If that's the case, why not change the inflation onset rate? The Blues' F-18s have a modified control system, so why not a modified anti-g system that only kicks in above, say, +5 G?
Lurking123, that's not the first time I've heard that. A well-known US PPRuNer said more or less the same thing.
