JAA made it 3000m for JAA licenses (unless accompanied by an IR or IMCR).
Incorrect, the JAA minima was 1500 metres, it was the UK that did not accept this and retained the 3k minima from National licence privileges via Schedule 7 (Then Schedule 8). EASA has adopted the JAA figure hence the change. Any other European JAA licence was not restricted to 1500 metres like the CAA version.
