I've looked at both Apple II FS-II scenery disk images and the C-64 disk
images. The Apple II ones don't seem to have any disk directory on
them, although you can see text for various regions/airports throughout
the disk.
The C-64 scenery images I've looked at have one file on them that's one
sector long.
I think both scenery disks are in some SubLOGIC-invented format, and
there's no file to copy from one platform to the other.
Furthermore, the Apple II disks have regions that look very much like
hi-res graphics data.
I'd be very surprised if the C-64 scenery disks were not specific to the
C-64 version of the flight simulator, and are not transferable at all.
What I'm sure about is that you won't find any tool that can copy the
file from .D64 to .DSK, because there aren't any files to copy.
This is the "FLIGHT SIMULATOR" file from the C-64 disk. First two bytes
are the track/sector link, and mean no more tracks, and 255 bytes (and I
don't see how that works when there are only 254 bytes left in the
sector).
There's some 6502 code starting at +0x25 (jsr $ff8a), and so on until
+0xb8 (jmp $03de). I don't know any of the C-64 ROM calls, so I cannot
say what this is trying to do, but it's making lots of KERNEL calls. It
might be reading sectors off the disk?
C-64 track 18, sector 2:
