FIXED POINTER
This is the more common of the two types of attitude indicators. The illustration
above shows a 10° right bank. The pointer and airplane move 10° with the
aircraft while the horizon bar and roll dial are gyroscopically stabilized. We call
this a “fixed pointer” instrument because the pointer is fixed to the frame.

MOVABLE POINTER
This illustration shows a 10° right bank. The roll dial and airplane move 10° with
the aircraft while the horizon bar and pointer are gyroscopically stabilized. The
roll dial is fixed to the frame but the pointer is not. This type of instrument is
sometimes referred to as a “sky pointer” because the pointer always points up.
