There are currently 3 dec's for the 310 in class, which is not exactly what I would call "DEC's all over the place". (LHR Rain you will never learn will you son)!
I saw one of the 777 FCTI's last night and I asked him if we had any DEC'S in class for either the 330 or 777 and he said "hell no".
Regards,
330 Man
