General
SHZ 009-999
The standby attitude indicator has a gyro-stabilized ball that
shows horizon position to the pilots. A roll scale is on the top of
the indicator case. The roll indication shows with marks at 0, 10,
20, 30, and 60 degrees.
SHZ 001-003
The standby attitude indicator has a gyro-stabilized ball that
shows horizon position to the pilots. A roll scale is on the top of
the indicator case. The roll indication shows with marks at 0, 10,
20, 30, 45, and 60 degrees.
SHZ ALL
A pitch scale is on the face of the attitude ball. The pitch angle
shows with marks at each five degree increment. Numerals
show at each ten degree increment. The fixed airplane symbol
is on the case of the indicator and does not move.
Control
The standby attitude indicator gyro will align to vertical in these
two ways:
* In the automatic mode, application of power causes the gyro
to align to vertical at a rate of three degrees per minute
* In the manual mode, let the gyro spin for thirty seconds. After
thirty seconds, pull the cage knob. The cage knob aligns the
gyro to vertical and makes the attitude ball stable at zero
degrees pitch and roll.
The approach mode selector has these positions:
* Off - no ILS or GLS data on indicator
* APP - ILS or GLS localizer and glideslope data shows
* B/CRS - back course ILS localizer data shows.
Indications
The normal ILS or GLS indications are the glideslope and
localizer deviation pointers in view and the LOC flag and G/S
flag out of view.
When the ILS or GLS data is no computed data (NCD), the
related deviation pointer goes out of view.
When the indicator receives incorrect ILS or GLS data, the
related deviation pointer goes out of view and you can see the
failure flag.
When you select B/CRS, the localizer deviation pointer
reverses polarity for the approach display. The glideslope
deviation pointer is NCD and is not in view during B/CRS
approaches.

Training Information Point
It is necessary to remove power from the standby attitude
indicator twenty minutes before you remove the indicator. This
will give the gyro time to stop spinning.
