There in the Ready Room, a large mental process starts. The mission for that hour and a half night flight has impact. Simple practice air intercepts don't require much effort and concentration that might drain away the acumen so desperately needed from the holding pattern on into the final approach and trap. But sea search and surveillance puts you low to the dark ocean and requires constant instrument flying skill. Little things bug you at night.
Comfort counts, it's easier to fly.
The short walk to the riggers shop from the Ready Room to suit up starts the mental game. All gear is checked with special emphasis on flares, survival radio, and flashlight. Out the riggers shop working your way to the catwalk along the side of the ship and up onto the fight deck. Being careful as you walk to the aft end of the ship where your fighter is always parked is an understatement. There are wires and fiddle bridges.
