nose goes up, wing stays down??
mm43;
i'm not a pilot - so maybe that's why your graphic confuses me: there's a 13 deg nu-angle depicted between "attitude" and "chord" - to me, this looks as if ' the nose would go up, while wing doesn't move with it' - should the chord not only differ from the attitude by about 3 deg?
The THS (trimmable horizontal stabilator) was trimmed 13° to the aircraft nose up position. To get an aircraft nose up command, the THS is trimmed 13° down (leading edge of the THS down). The line "Attitude" basically represents the fuselage, and the zero position of the THS.
I think that should explain it.
