descends through 2500 feet above ground level (AGL) and disappears as the airplane
climbs through 2500 feet AGL.
Analog Radio Altitude Scale
A small window appears at the center of the scale as the airplane descends through
1250 feet AGL. This window marks the current radio altitude. This value is
numerically repeated in the bottom portion of the attitude indicator.
An analog radio altitude scale appears as the airplane descends through 1100 feet
AGL. This analog scale is used in conjunction with the ground bar (rising runway) to
assist in visualization of the aircraft’s height above terrain. The scale contains line
marks and single-digit numeric labels. Each digit indicates 100 feet of radio altitude.
At Decision Height (DH), the numeric label and scale change
from green to yellow.
Ground Bar (Rising Runway)
A ground bar displays on the analog radio altitude scale to represent the terrain. As the
airplane descends through 200 feet AGL, the ground bar rises on the analog scale. At 0
feet radio altitude, the top of the ground bar aligns with the center of the scale.

Standby Airspeed Indicator
The airspeed indicator supplies non-corrected (indicated) airspeed. It uses the standby
pitot source P3 and the standby static ports S3.

Standby Altimeter
The standby altimeter incorporates an altitude pointer and an altitude counter. The
altitude pointer and altitude counter operate through a mechanical linkage connected
to a pressure capsule. The pressure capsule moves with changes in static pressure.
Barometric correction is selected by a knob at the bottom right of the instrument and
displayed in inches of mercury and hectopascals. The instrument receives its static
pressure from the standby static ports S3.

Standby Attitude Indicator
The standby attitude indicator has an electrically-operated vertical gyroscope. The
gyroscope is mechanically connected to the sphere to show attitude information. To
cage or uncage the instrument, the PULL TO CAGE knob is pulled and turned. When
the instrument is uncaged, the cage knob is turned to adjust the pitch reference.
