When I got into commercial aviation, the limit was 1,000 hours per annum. The normal limit was 100 hours per month but it was possible to do 120 hours if you had a quick medical check-up at the 100 hour point.
When I started flying on the N-register, the rules were 100 hours in 30 calendar days up to a maximum of 300 in 90 days. It was quite legal to fly 120 hours in a 30 day period (international) as long as 300 in 90 was not exceeded.
I have it in my mind that the 900 hours per annum limit came in with JARs so are we not just going back to where we were?
Please don't get me wrong; I am not saying that this is a good idea but I do wonder if we are not going back 30 years.
