737 (MAX Only?) control box on glareshield
Looking at pictures of a MAX cockpit, I spotted a strange "box" sitting on top of glareshield. Forgive me if it's a lame question (Airbus pilot here), but what is it? My guess would be something to do with HUD, but it's a strange place to put it (actually to put anything at all). Or maybe just some test/certification equipment?
I'm not allowed to post url/photos due to "too low post counter", but just google "737 max cockpit" to know what I mean
