I believe the objectives state the recovery CVs are for landing only. They are there to be a safe place to land in case all of the in-action carriers in your area are destroyed.
forHIM has it right. I've read and been told as soon as you land on a recovery CV (they are behind the main CV groups and are not targets), your night is over.
Do you have this in writing? I do not see it in any of the 3 frames objectives.
the "recovery" carrier is for landing only. If you wish to rearm land at another CV. The reason behind the recovery CV was to give each side a guaranteed place to land before the end of the frame.
