Basics
182 Flyer
Basics unfortunately have nothing to do with flying a jet at high altitude close to the "coffin corner" and then having supercooled water (ice) block all 3 pitot tubes simultaneously, build up on the wings increasing the weight and changing the C of G. This is a totally different kettle of fish. The way to prevent this type of incident is to stay away from CBs when close to the coffin corner. That's what they didn't seem to have done.
