A bit of an anoraky question but I've noticed a few photos of planes recently where the wheels sit in holes under the AC but aren't underneath doors. I think one was an Embraer? When I look at Imap on VS it says outside air temp -45C. So I'm wondering how they withstand this without the rubber becoming brittle. Perhaps even with doors it's the same temperature and it just streamlines the AC better but I'd always assumed there was a little heating there to keep the temperature up.
Anyway, just wondering ...
