However one thing I would like to know, is there some sort of regulatory restriction on aerobatics, I noticed that the majority of the display was basically a flat tail chase with very little else, except for the TF51. This was something of a surprise to someone use to the displays at Duxford etc….
Frankly, the one display I saw at Duxford years ago was downright scary. A tailchase between two different aircraft that were very low and performing loops without much energy. It looked like one false move (or engine sputter) would cause them to come spinning out of the sky.
I think that the "Bob Hoover" style using energy management is commonly seen in the US. No matter where during flight the engine might fail, there is enough energy available to make a safe landing.
My understanding is that airshows are waivered in the US, as are the pilots performing aerobatics. The aerobatic sequences are also segregated from the fly-bys. Pilots doing the fly-bys don't need any special credentials besides a pilots license. I think there may be some recent requirements for formation flights during shows though.
