Can contrails and smoke reveal enemies?
Yes. Bandai Namco says contrails, black smoke and reflections can provide visual cues to aircraft positions beyond radar alone.
Confirmed explanation
These cues reward looking outside the central HUD and tracking movement in three dimensions. Radar remains available with multiple scanning positions, so visual awareness supplements rather than replaces instruments.
What is not confirmed yet
Visibility distance, graphics-setting dependence and accessibility options are not yet specified.
