7.1 Mechanical Instrument Replacement
Approval is granted to replace legacy mechanical instrumentation as
follows:
•
Installation of the AV-30-C (Dedicated AI mode) as the primary
source for attitude and slip. Installation replaces the existing stand-
alone vacuum or electrically powered attitude indicator.
•
Installation of the AV-30-C (Dedicated DG mode) as the primary
source for direction-of-flight. Installation replaces the existing stand-
alone vacuum or electrically powered non-slaved directional gyro
indicator.
Note that when installed as a DG, a reversionary AI is available for display.
This functionality is supplemental only and does not satisfy requirements
for a backup or standby attitude, turn and slip, or turn coordinator.
7.2 Non-Required Instrument Addition
Approval is granted to install the AV-30-C as a non-required instrument,
augmenting existing required instrumentation. In this configuration, the
AV-30-C must not replace an existing required instrument.
7.3 Vacuum System Removal
The aircraft’s vacuum system typically may be removed under a field
approval process (FAA Form 337) if no other systems or equipment
requires it. The AV-30-C installation approval does not address this
alteration.
