I have already commented this on technical issues, but it really deserves it's own discussion

This update has fxcked the air units, wheel/airborne mode will not work for majority of the aircraft apart from the typical gunships. We can no longer manually fly aircraft, and any air units spawned in must already have a crew plus be in airbourne mode with an altitude of above 10 to fly prematurely. This makes scripting take-offs and landings a nightmare to achieve.

Edit, I have a guess where the engine needs to be toggled on and off, but unlike valour, there is no engine toggle to switch either in game or triggers to script it.

Edit 2, I've tried air_state, but snowspeeders wont respond to changes in altitude. I've tried using different offsets on waypoints to change the altitude, I've tried zones to dictate altitude. Nothing works.

The only way air vehicles work is if they are prematurely set to airborne mode and have a greater altitude of 0.5. They also have no collision properties, glitching through the map or changing their altitude parallel with the terrain which looks glitchy as hell. No, this update has definitely screwed up aerian vehicles.

Edit 3: I'll leave this up publicly as it will be useful for future reference.
