Desert185: Thanks for the info.
Lomapaseo: The heat issue is exactly what concerned me. Without a definitive "yes" I'm not going to do it.
Fargo & spanner: Why do I want it there? I've got all the en-route charts as well as plates for the whole world as well as weather, notams, all the aircraft manuals and performance info. These are normally stored in a locker which is hard to reach and the folders are large and cumbersome.
We have loads of other stuff which hasn't been approved by the regulator in the FD. There's a laptop in one of the bins, my glasses get perched on the side next to the printer, the clipboard with the OFP gets dumped wherever is convenient at the time.. OK, the bins are probably approved for storage, but does that make them the only place where we can put stuff?
