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.
