previous.

Instructions:

In the Flags and Abnormal Conditions section of the SN3308 Pilot's

Guide update as follows:

1) Under the CONDITION column, line out the words

"Fluxgate failure" and replace with FLUXGATE TOTAL

ELECTRICAL FAILURE"

2) In the DISPLAY column, to the right of Fast Slave Mode,

write "See PG Insert" to refer to the following information:

The following explanation applies when the SN3308 is installed

using 'internal slaving'. This is an installation-selected mode and

is used with most remote DG's such as KG102 or Mid Continent.

A fluxgate is an electronic compass sensor, with most of the

characteristics of a wet compass. The fluxgate is the only sensor

which provides heading to the SN3308. The remote Directional

Gyro turns the SN3308 compass card directly, but does not know

which way North is. The fluxgate supplies North and thereby the

SN3308 ensures correct compass card orientation, slowly and

continually correcting for gyro drift by using the North input from

the fluxgate. This correction occurs at 3 deg/minute. It is

imperceptible in flight.
