Hawaii to mainland, Tailwinds or Headwinds
Simple question. Flying from Hawaii to the mainland, will you have a headwind or tailwind. A particularly stubborn acquaintance swears you'll have headwinds going east because of the trade winds. He flew Cessnas in the islands, and this was the case there. I flew this route in Navy C-40s/737 for ten years, most of which as an over water international instructor and know that prevailing westerlies equal winds from the west 99% of the time, but oh well. What do I know? Lol.
I showed him the winds aloft chart, but he swore it showed East winds. I showed him wind barb explanations from Google, but he said they're wrong. Lol. Anyone have a good reference that I can show him, because I'm out of ideas.
