How about pilots who climb in speed mode? Particularly at high altitudes.

"Should I advise center we're climbing at 100 f.p.m.?" is my usual comment for this technique, as the airplane wallows from 100 f.p.m. to 900 f.p.m.

My favorite response to my nausea reduction technique written above, from an individual I'm scheduled to fly with a couple of times next month (the most "making stuff up" individual I've ever flown with):

"You should climb in speed mode while in icing conditions so you don't risk stalling the airplane."

How about being a professional pilot and monitoring what the aircraft is doing?
