MODE SELECT BUDON -- When
pushed, will select the altitude hold mode. This mode
provides capture and tracking of the selected altitude. The
selected altitude is the airplane altitude at the moment the AL T

established VS rate present, there will be approximately a
10% (of VS rate) overshoot, with the airplane returned
positively to the selected altitude. This button may be used to
engage the autopilot.

mode) and the UP button is pressed, the autopi lot will modify
the displayed VS command (FPM) in the up direction. Sing le
momentary cycles on either the UP or DN button wi ll
increment the VS command by 100 FPM per cycle. When
either button is continuously held in, it will modify the vertical
speed command by 300 fpm per second .
