FLIGHT INSTRUMENTS (Continued)
HORIZONTAL SITUATION INDICATOR (Continued)
WHEN THE AUTOPILOT IS ENGAGED IN NAV, APR OR
BC OPERATING MODES, IF THE HSI NAVIGATION
SOURCE IS CHANGED MANUALLY, USING THE CDI
SOFTKEY, THE CHANGE WILL INTERRUPT THE
NAVIGATION SIGNAL TO THE AUTOPILOT AND WILL
CAUSE THE AUTOPILOT TO REVERT TO ROL MODE
OPERATION. NO AURAL ALERT WILL BE PROVIDED.
IN ROL MODE, THE AUTOPILOT WILL ONLY KEEP THE
WINGS LEVEL AND WILL NOT CORRECT THE
AIRPLANE HEADING OR COURSE. SET THE HDG BUG
TO THE CORRECT HEADING AND SELECT THE
CORRECT NAVIGATION SOURCE ON THE HSI, USING
THE CDI SOFTKEY, BEFORE ENGAGING THE
AUTOPILOT IN ANY OTHER OPERATING MODE.
VERTICAL SPEED INDICATOR
The Vertical Speed Indicator (VSI) tape is found on the right side of the
altimeter display along the upper right side of the PFD. The vertical
speed pointer moves up and down the fixed VSI scale and shows the
rate of climb or descent in digits inside the pointer. The VSI tape has a
notch on the right edge at the 0 feet/min index for reference. Rate of
descent is shown with a negative sign in front of the digits. Vertical
speed must exceed 100 feet/min in climb or descent before digits will
appear in the VSI pointer.
