Hi All - I' searching for some stats to put things in context for the SSA presentation. Much obliged if anyone can provide sources for:

Annual stats from 1950s forward, USA and world totals:
- IFR flight-plans served
- active aircraft
- aircraft produced including GA (and LSA or as Europeans call them ultralights)
- TCAS-equipped aircraft

Thanks in advance for any help,
Best Regards, Dave

I would have to guess AOPA & IAOPA would cover some of that. FAA (if you can dig through the info) will also have a lot of that for the US.
