Most commands are back to the classic (2/300). A few managed to go straight onto the 400 in CNS though.
Requirements are;
1 year in the company, and
700hrs on company aircraft, and
2000hr aeronautical.
The last one was previously waived if you had 2000hr on company aircraft. Caught a few out who knocked back a classic command hoping for the 400, and now have to wait for the 2000 aeronautical.
