Anyone done a SOIA for real?
Point 86 makes several points:
1.ADS-B is a little way off, even in the US. Yes,but if we are going to do better than SOIA, we need to start developing the role of ADS-B in next generation closely spaced IMC approaches. For example the recent NPRM does not include the parameter roll angle, which is a visual cue that would give the trailing pilot maximum warning of a blunder by the leading aircraft.
2.I used the term"S-turn", but perhaps this is wrong terminology. It means doing a turn towards the runway when visual, followed by an opposite turn to align with the runway.
3.I am not against SOIA per se, but I was trying to find out what actual users thought of its value in practice. Also, what do pax make of it, and do you tell them beforehand?
4.What I do find disturbing is the official attitude, saying that SOIA is the bees knees, and seemingly nothing further in the NextGen plans
