Q
Important notes on operation
A
- Attitude Indicator does NOT indicate direction of flight, simply, were your nose is pointed and how your wings are positioned.
- In extreme attitudes, the AI gyro may „tumble” out of axis and will take a certain amount of time to recover.
- Once level flight has been established, align the miniature airplane with the horizon bar.

Q
Attitude indicator pendoulous vanes
A
pendoulous vanes are small, mechanically linked vanes used to keep the gyroscope upright in vacuum-powered instruments. These vanes swing in response to gravity, and when the gyroscope is tilted, they swing to either cover or uncover air ports, creating a precession force that realigns the gyroscope to the vertical.
