2 QRC questions
So I ran out of my company approved reading material on a 3+ hr flight today, and the QRC was sitting there all lonely, so I read the end; Doors and Misc, and I have two questions about some of the stuff in there. First, on p.2-244, they talk about "a constant 1 'g' level turn" when discussing vertigo. Now, I am no physics wiz, but it would seem to me that in turning level flight, the g force will always be a value greater than 1 due to constant acceleration in the turn. Maybe they meant constant g turn.....
Second, in regards to mach tuck, p.2-235 says something like "the center of pressure on TOP of the wing moves aft, causing a pitching moment downward." I have always thought of the center of pressure as acting through the bottom of an airfoil. Maybe they are talking about the shock wave on top of the wing moving aft. But the center of pressure below the wing moves aft, furthur from the center of lift and causes the the aircraft to pitch down. Discuss, oh wise pipe
Yariv? Vortex? anyone?
