Airbus Strobes
I know that Airbus wing strobes double flash together, hence how you can always tell an Airbus on approach. However a few nights ago an A321 departed LHR with the wing strobes double flashing on alternative wings, as in left then right and so on. Does anyone know why that would of been? I've never seen the lights flash like that before.
Btw I'm not a pilot so I apologize if this isn't worded very well.
