This looks similar to that of an attitude indicator.

The turn coordinator should be used as a performance instrument when the attitude indicator has failed.

Some attitude indicators can only tolerate a specific range of bank angles.

Note that air driven attitude indicators have a different operating principle.

You're probably the only one in the whole tribe who can't tell an altimeter from an attitude indicator!

Glancing at his battered console, he saw that the green light was the attitude indicator.

The attitude indicators showed the plane in a steepening dive.

A second strike at 52 seconds after launch knocked out the "8-ball" attitude indicator.

The two small wings on the plane's attitude indicator were steady above the artificial horizon.

The attitude indicator is designed to look very much like traditional mechanical AI's.

A backup attitude indicator was working, the safety board's report said, but it was smaller and several feet away.

Jesse looked at the attitude indicator and picked out the thirty-degree mark, then rolled the airplane to the right.

Glenn noticed that the attitude indicators disagreed with what he observed were the true spacecraft attitudes.

Miniaturized devices using this principle are a relatively inexpensive type of attitude indicator.

It also showed that the captain's attitude indicator, which gives the plane's orientation in relation to the horizon, was broken.

The captain of the aircraft had maneuvered it according to erroneous indications on his attitude indicator.

But "loss of the primary attitude indicator alone does not explain why the pilot lost control of the airplane and crashed," the board's report said.

To the left and right of the attitude indicator are usually the airspeed and altitude indicators, respectively.

Beside that was the airspeed indicator, then the attitude indicator, and finally the altimeter.

Some attitude indicators can be manually erected once the airplane is in level flight using the caging mechanism.

He climbed nearly a thousand feet before he finally regained control and started believing the attitude indicator again .

For this reason, some attitude indicators are fitted with a "cage" (a device to restore the gyroscope to an erect position).

Electrically driven attitude indicators typically use mercury switches to keep the gyro axis vertical.

The artificial horizon told him he was approaching level flight again.

That reference point was just above the artificial horizon line and quickly drawing near.

It added an index arm with spirit levels to provide an artificial horizon.

The pilot's eyes immediately flicked down to the artificial horizon.

However, with the artificial horizon, the eye vane is not required to be used.

The little airplane on the artificial horizon shows our attitude with relation to the earth.

It adds an index arm and artificial horizon to the instrument.

It can also be described as the artificial horizon that a city's overall structure creates.

She glanced at the artificial horizon, then tried to get a gut feeling based on her thousands of hours in flight.

In his equipment there was a mercuric artificial horizon mirror.

Other instruments provide backup information that validates the artificial horizon.

Watch the artificial horizon and keep it level.

If it'll help I'll bring up an artificial horizon on your display aft."

The two small wings on the plane's attitude indicator were steady above the artificial horizon.

Most had artificial horizons to permit taking a sight through a flush overhead window.

You must then check that all instruments like the artificial horizon and altitude metre etc work.

Sperry is also credited with developing the artificial horizon still used on most aircraft in the early 20th century.

The altimeter continued to unwind, the artificial horizon still swirling.

The artificial horizon swirled and jogged as the wind tossed the aircraft.

Others prefer to use a lit artificial horizon.

The probable cause of the accident was the failure of one or both artificial horizon instruments.

Tank's artificial horizon toppled (the cause is not explained).

These include the main displays and the backup artificial horizon, which was an analogue display prior to this.

'That I believe/ the colonel said, checking his altitude, compass, and artificial horizon.

Speculation at the time at Pan Am on the cause of the accident also considered a catastrophic windshield failure, as well as gyro horizon instrument failure.

Most modern instruments are designed to tolerate 360 degrees of rotation in pitch and roll without tumbling, although periods of violent aerobatics may tumble any gyro horizon.

Captain Herschel Laughlin's gyro horizon had inadvertently been left caged - while the instrument displayed level flight, the aircraft entered a steepening bank to the left.

The Gyro Horizon Enables Instrument Flying A history of how aircraft instrumentation was developed with an emphasis on the gyro horizon.

An attitude indicator (AI), also known as gyro horizon or artificial horizon or attitude director indicator (ADI, when part of a flight director display), is an instrument used in an aircraft to inform the pilot of the orientation of the aircraft relative to Earth's horizon.
