Might not be required, but
when doing a recurrent, can you specify, the cert that your airframe is certified to.
Two crew from different companies working to different certs, not my idea of safe training.
For exampe I was on a G550 D recurrent a few weeks ago, and the other guy was only C, as freelancer, not safe, as we had different ideas re the lates options on the big boys toys.
Lastly, I wish you luck on the contract work, feel free to PM me with your overflow, there are very few good experienced crew in the contract market these days.....hint hint.......ssa
