What filters are used on a typical vacuum system for gyroscopic instruments?

Air filter – A master air filter screens foreign matter from the air flowing through all the gyro instruments. It is an extremely import filter requiring regular maintenance. Clogging of the master filter reduces airflow and causes a lower reading on the suction gauge.

Is a gyroscopic instrument failure an emergency?

A pitot-static or gyroscopic failure can be difficult to diagnose and confirm at first. In any case, the quick and proper diagnosis of an instrument or system failure will turn an emergency into an inconvenience (although you should always declare an emergency when the situation warrants).

What are the gyroscopic instruments?

The most common instruments containing gyroscopes are the turn coordinator, heading indicator, and the attitude indicator.

What is suction gyro?

Gyro pressure gauge, vacuum gauge, or suction gauge are all terms for the same gauge used to monitor the vacuum developed in the system that actuates the air driven gyroscopic flight instruments. Air is pulled through the instruments, causing gyroscopes to spin.

Why are gyroscopic instruments not used in aircraft?

More modern gyroscopic instruments are built so they do not tumble, regardless of the angular movement of the aircraft about its axes. In addition to the contamination potential introduced by the air-drive system, other shortcomings exist in the performance of vacuum-driven attitude indicators. Some are induced by the erection mechanism.

What are the sources of power for gyroscopic instruments?

Originally, gyroscopic instruments were strictly vacuum driven. A vacuum source pulled air across the gyro inside the instruments to make the gyros spin. Later, electricity was added as a source of power. The turning armature of an electric motor doubles as the gyro rotor.

What happens to gyros in a smoker’s airplane?

In the event of a vacuum pump failure, debris will not be scattered through the system and deposited into expensive, sensitive instruments. There is a filter inside the cabin that removes particulates from the air going into the gyros. It’s generally true that the gyros will lead shorter lives in a smoker’s airplane.

Do you need a vacuum pump for a gyroscopic instrument?

Since there is no air flowing through an electric attitude indicator, air filters, regulators, plumbing lines and vacuum pump (s) are not needed. Contamination from dirt in the air is not an issue, resulting in the potential for longer bearing life and less precession.
