The exact same source of confusion often arises when a pilot who is used to focusing his attention mainly on the (Western style) attitude indicator tries to fly primarily by reference to the "turn coordinator"- where the moving thing is the airplane, not the horizon. It is very common for relatively inexperienced pilots to react in the "wrong ...
No outside force is applied to the gyroscope until the mechanical limitations of the instrument are reached. Once the mechanical limitations of the instrument are exceeded, the attitude indicator may tumble. In the case of the Directional Gyroscope, on the other hand, it is constrained to move freely only upon one axis relative to the fuselage.
The attitude indicator is very important for any sort of instrument flying, so it must be accurate at all times regardless of the plane's movements. I presume that the indicator would be connnected to a gyroscope. However, gyroscopes drift, and a drifting attitude indicator would be pretty useless. Of course, you might have a reset button, but ...
Attitude is visualized using an attitude indicator (aka artificial horizon): Attitude indicator, indicating 5° right roll and 10° down pitch. In some applications attitude may include heading as well, and thus becomes a synonym for orientation in space using the three angles: heading/yaw; pitch; roll/bank.
The instrument reading is directly derived from a gyroscopically-leveled, essentially precession-free, gimbal-mounted sensor. There is no binding of the freely moving instrument sensor within the instrument case. This excellent video by Ryan Anderson explains clearly the operation of the freely-moving instrument sensor.
Often times when a gyro starts to fail, you will notice it slow to stabilize when first starting the engine. A healthy attitude indicator will become erect almost immediately. If it wobbles for more than a short moment, be suspicious. Also become suspicious when a gyro become loud or whines.
Attitude Indicator. It shows your attitude (nose up / down, bank left / right) relative to a horizontal surface. Basically, it tells you the orientation of the plane if someone were to take a photo of the plane from the outside at this very moment. It does not tell you which way you are going (e.g. you can be nose up but descending). Turn ...
$\begingroup$ Attitude indicators (AIs) in Soviet Bloc aircraft operated opposite to the way western AIs worked, and cause numerous accidents in pilots converting to western designed aircraft after the fall of the Soviet Union. In these AIs, the background remained fixed, and the little aircraft moved around.
The airplane symbol on the attitude indicator reaches the second white line on "ground" on the left side. Conclusion: the turn and slip indicator and the attitude indicator show more or less the same angle on the roll axis. The differences are: turn and slip indicator is limited to a specific angle, the attitude indicator works beyond this angle.
5. G1000 is a multi-unit system. The attitude information comes from a specialised unit called AHRS (Attitude and Heading Reference System), typically GRS 77. AHRS uses two solid-state gyros (vertical and directional), plus a magnetometer, to obtain a complete attitude information. In addition, AHRS does employ accelerometers and rate gyros.
