The main reason is for the JAA not having a written for the IR is because their regulations are geared mainly to the airlines. The FAA regs are still written to allow that 60 year old guy go fly his J-3 Piper Cub around with as little hassle and as safely as possible. Its still possible to fly a vast portion of the States without a radio or transponder, or filing a flight plan.
