Roll Scale Zero
The standby mechanical Attitude Indicator in your aircraft is either a Ground
Pointer or a Roll Pointer configuration. The GDU 620 Attitude Indicator has
been configured in either a Ground Pointer or a Roll Pointer configuration to
match the configuration of your aircraft' s standby Attitude Indicator. Ground/
Sky Pointer mode is configured during installation and can not be changed by
the pilot.
In an aircraft with an Attitude Indicator that has a Ground Pointer, the pointer
above the Roll Scale shifts with the roll or bank angle of the aircraft to keep the
Roll Scale Zero Pointer pointing towards the ground.
