Lomcevak - here is another saying...don't shoot the messenger!
I don't think AH's other flying is a factor. If currency was something to look at then I'd start with simply looking at the time on type doing aeros, and from a relevant height.
I merely linked the F3 report as someone asked the question.
Meanwhile this film shows the pilot and aircraft perform the initial (and relevant) part of the display in July 2015. It shows (I think?) the 1/4 clover with the rolling element downwards, is it different to the Shoreham display, where I see the rolling upwards? its not that easy to tell in the Bray film but it doesn't look as if its rolled anywhere near as much until the back side of the loop?
It certainly isn't a very easy figure to judge accurately as it doesn't seem to be clear what the figure really is. Although regardless of the heading change it should be clear if you are rolling up or down and I still don't see how that is a standard figure under CAP403. Just a view.
