Is it really true that BA only allow their F/Os to land in 2/3rds of the aircraft crosswind (demonstrated) limit?
If true, you obviously don't have much faith in them!
Our F/Os have no such get-out clause and have to be able to hack the full 35 knots across.
Furthermore, I have been a TRI/TRE for donkey's years and have NEVER signed a F/O's license as P2. I can't believe this happens.
