I would like to suggest the implementation of aircraft anti collision beacons across various routes. There are various examples of tall buildings, obstacles and tower cranes that have no red anti collision lighting at present, which is glaringly obvious in hours of darkness trips. Surely this would be a fairly simple fix for improved environmental immersion.
+1 yes there should be, as per FAA in the U.S.A. anyway, and I'm sure it's the same type of rules in the Europe / UK
A couple of UK examples include... Gasometer tower at Southall GWE Tower cranes between Dartford and Swanscombe SEHS Buildings on London skyline various routes Radio mast near Huddersfield (if updated) NTP TV masts at Croydon and Crystal Palace (if updated) BML Some of these buildings/obstacles are already featured in game with others needing inclusion in an update at a future point. Furthermore, some are red beacons, with others illuminated in white.
