WH904
I am quite a fan of many of your posts on other topics but I think you may be a tad out of your depth when it comes to air displays and validation of same.
Just to mention one of many points that make validation flights necessary, pilots need to see the actual/best visual cues on the ground to sort out their speed and height gates (to say nothing of turn rate issues) especially when the surrounding area has complex height and avoid areas. The validation flights are really practice opportunities for the pilots - during which the display supervisors also have an opportunity to check that the display flown is in accordance with the brief submitted in writing by the pilot in the weeks before the show.
Farnborough specifically is a tricky area in which to fly a display and even the Red Arrows do a validation flight there to help their leader get himself sorted.
In my opinion your comments regarding Farnborough's rules do not reflect what it is like to fly a display there.
