Meanwhile, I've been following your advice in AFCAD. I've increased the number of dedicated cargo parking spots and the freighters have taken advantage of them. So that problem is solved. Thank you.
I've made a tentative start on the museum, using aircraft from the California Classics AI selection. I've installed nine so far just to try out my plan and they may or may not remain on display. As you can see, I've created a small display area round the corner in the cargo area by deleting one of the large parking spaces. They are designated with a code: DISP (for display) and the nine aircraft have that code in their aircraft.cfg, which obviously works. To keep other aircraft out I've designated them 'parking' spaces (as opposed to 'gates') and specified that in the aircraft.cfgs also.
Anyway, here's my first attempt at AFCAD:
