Ah, Beaver, the good old days....
Sprint to the aircraft to try and beat the loaders / refueller / caterer. Crank up Hotel mode for a few minutes to take the chill off before they arrive.
Turn up the chart light on the control yoke, and clamp the headset onto it to warm up the gels. Turn on all the filament tests, close the overboard valve and try to glean half a degree centrigrade from somewhere.
Its almost enough to make me feel nostalgic
