text: Depending on the aircraft design and flight regime, its tailplane may create positive lift or negative lift (downforce).
text: In this case, angles with a positive mathematical sign, such as +3 , mean trimming of the horizontal stabilizer in the aircraft longitudinal direction (X) seen from above, which is associated with an increase in the positive lift of the horizontal stabilizer, and thus with rotation of the aircraft about its lateral axis in the sense of reducing the pitch angle, while angles with a negative mathematical sign, such as -15 , mean trimming of the horizontal stabilizer downwards, so that the horizontal stabilizer produces negative lift, thus resulting in an increase in the pitch angle of the aircraft.
text: Depending on the aircraft design and flight regime, its tailplane may create positive lift or negative lift (downforce).
text: The horizontal stabilizer 20 has an aerodynamic profile which, for trimming purposes, can be varied such that it produces aerodynamic forces whose magnitudes are variable such that the horizontal stabilizer 20 selectively produces positive lift or negative lift, or is neutral.
