For example, what would be the pitch attitude according to the standard definition, of the aircraft in sustained inverted flight as described in my comments above? | |

You are free to define your pitch angle differently from everyone else, but then please accept that your opinion will lead to different results. And the results of others aren't necessarily wrong only because you choose to pick a different definition. | |

So that's a difference of 20 degrees-- nowhere near 180 degrees. Even if we double the angle-of-attack to 20 degrees we just get a difference of 40 degrees, nowhere near 180 degrees. | |
| Nov 29, 2018 at 3:07 | comment | added | quiet flyer | "Now consider flying inverted: Both are almost 180° apart."-- what do you mean by this? When I think of flying inverted the first thing that enters my head is sustained inverted flight. Let's say the aircraft is designed for aerobatics and has a symmetrical airfoil with zero incidence. What would a typical angle-of-attack be in sustained inverted flight, maybe minus 10 degrees? | |
