Back to FAI

Thank you for asking this. I was searching Google today to try and discover when this happened. I found a couple interesting documents on the history of the rules in the US but nothing about the split spoken of in the other thread.

It has been established in the other thread that most countries adopt the international rules with limited modifications and translation. US and Canada are apparently outliers.

Were the US rules at least close to the FAI/IGC at one time?

It is same for aerobatics in the U.S.A.
The international (FAI) rules have changed for what types of programs will be flown. The american aerobatic agency, the International Aerobatic Club, has decided to not change to match the FAI.

Take heed my brethren and learn from thee ways...

Most wondrous pointeth to showeth a parallel between a'robatics and soaring.

F'r the w'rld championships of the lasteth 28 years, thee usa hast not wonneth since 1988.

Or doth thee desires of heart dream of being a loser?
