When you get tired of the seemingly nonsense, hop the trash bag. Then you can decide to skip dicing with frost on the wing, outside the ‘box’. You can also happily drive at .80/315 into moderate turbulence.

Yeah, when out of the country at a non-maintenance base, write up that smudge on the aft, underside of the wing as a potential bird strike.

Yep, do all that and more.
