What is gimbal error aviation?

Gimballing error occurs when the aircraft is banking due to the movement of the outer gimbal against the stabilized inner gimbal during a large banking turn, these errors can cause erratic rotation of the compass card even in a steady turn.

What are the errors in DGI?

There are two main errors on an directional indicator gyro: friction drift, gimballing error.

When an aircraft has turned 270 degrees with a constant attitude and bank the pilot observes the following on a classic artificial horizon?

28) When an aircraft has turned 270 degrees with a constant attitude and bank, the pilot observes the following on a classic artificial horizon: A) too much nose up and bank to high.

What is Gimballing error in gyro compass?

Gimballing error is caused by taking readings from the compass card when it is tilted from the horizontal plane. It applies to the compass itself and to all repeaters. To minimize this error the outer ring of the gimbal oach repeater should be installed in alignment with the fore-and-aft line of the vessel.

How is an error in a gyro repeater corrected?

This error is corrected by use of a second gyroscope called floating ballistic which stabilizes the mercury ballistic as the vessel rolls eliminating the error. Another method is to use two gyros for the directive element which tend to precess in opposite directions neutralizing the error.

What is precession error?

Precession errors can occur during rapid turns and changes in speed. When this happens, errors in pitch attitude and bank angle can be present. While these errors may not be too great, they can easily be identified and corrected for. During a rapid change of speed, additional g-forces can be exerted on an aircraft.

What does directional gyro indicate?

Directional gyros indicate the direction that the aircraft is heading.

Why are RAF aircraft fitted with DIC?

The DIC does however, have three significant advantages: It is very simple and therefore reliable. It is very cheap and lightweight. It does not require any form of power and so will continue to work even after a total power failure in the aircraft.
