I'm a carnal, organic anagram.
Here's what I'm saying; if you wouldn't do it with a fed sitting in the seat next to you, then you shouldn't do it. If you wouldn't say to the fed, "Aw shucks, Bob, it's only 2 degrees C, let's just go! It'll be fine!" Then you shouldn't do it.Ok, we can agree to disagree.
One simple question though...are you saying every Part 91 flight that flies to/from an airport where "having the data" is impossible, such as a mountain airstrip with no weather reporting available, is operating illegally?
Or hey, let me say it like this; if you wouldn't do it on a checkride, then you shouldn't do it. If you wouldn't say to the examiner, "Well, it's kind of hot out, so I ran the performance numbers, but it's a little too hot, but we'd be fine," then you shouldn't do it.
That's what I'm saying.
