What it probably came down to was (1) the RC pilot was not where he was supposed to be. (2) The full scale go-around was a result of the RC airplane being where it was not supposed to be. (3) The full scale had the right of way per FAR 91.113 (g) which states that “ Aircraft, while on final approach to land or while landing, have the right-of-way over other aircraft in flight or operating on the surface.” Lastly, the “event coordinator” is not ATC, therefore the “request” was not compulsory. Regardless, the full scale pilot complied with his requirements in that he stated his intention to execute a go-around – only to have the RC pilot who was not where he was supposed to be in the first place then execute another maneuver that put him in the path of the go around – thus being in the wrong spot not once, but twice.
The full scale was asked to go around well before he was even close. The CD was letting the RC pilot finish his demonstration. The full scale pilot did an aerobatic maneuver (high speed pass) without a waiver and was suspended because of that. He was not landing so he did not have right of way. IMO saying the RC aircraft should give right of way is a term that needs to be changed. The RC plane should always see and avoid full scale at all costs, but it is the full scale that is more capable of getting away so they should do the same.
