This is bizarre. I came into this thread to make this exact same comment - I play 2048 religiously during takeoff, turbulence, and sometimes landing. It works really well, though if you were to watch a replay of my game, you could tell when turbulence hits because I start making faster and less logical moves :)
Very bizarre, as I also found it helped with this! I was only a First Officer at the time, but even as a Captain today I find playing 2048 during take off and landing really helps.
Wait, you're a Captain, and you fear of taking off and landing? I have so many questions :). Also, as someone who is scared of taking off and landing, I'm even more scared now.
