Of the old basic six instruments, the turn and bank indicator is now obsolete.

He began carrying one of the first turn and bank indicators, given him by Sperry during their earlier testing.

He glanced again at the fuel gauge, altimeter, turn, and bank indicator.

For this and other reasons, many highly experienced pilots prefer the "older" turn and bank indicator design.

Instruments, either the turn and bank indicator or the turn coordinator, have the standard rate turn clearly marked.

A turn coordinator, or turn and bank indicator which helps the pilot maintain the plane in a coordinated attitude while turning.

With an improved artificial horizon, including gyros and flight directors, the turn and bank indicator became needless.

This is done by applying a pedal input in whichever direction is necessary to center the ball in the turn and bank indicator.

In aircraft, the "ball" in turn coordinators or turn and bank indicators is sometimes referred to as an inclinometer.

Although the turn and balance indicator is sometimes called the turn and bank indicator, the instrument does not give the aircraft's true bank angle.

The turn coordinator differs from the older turn and bank indicator in that the turn coordinator has the gyro mounted at a 30 tilt.

The aircraft was somewhat basic; instruments were airspeed indicator, altimeter, oil pressure gauge, tachometer, turn and bank indicator and compass.

Each pilot had proper dual controls, and the instruments included an air-speed indicator, a turn and bank indicator, air pressure gauge, compass, and altimeter.

When an aircraft is flying with zero sideslip a turn and bank indicator installed on the aircraft's instrument panel usually shows the ball in the center of the spirit level.

With a left wing low, for instance, the turn and bank indicator will show a left bank, and the compass will show a heading change to the left.

The Turn and Bank Indicator will be scanned continuously, with the Vertical Speed Indicator and Magnetic Compass.

The turn and balance indicator is often referred to under various names interchangeably, such as the turn and slip indicator or the turn and bank indicator.

The image indicates a wings level aircraft (i.e. the flight path vector symbol is flat relative to the horizon line and there is zero roll on the turn/bank indicator).

Once clear of the ship, Pitt kept his eyes on the TURN AND BANK indicator until the little ball held steady within the center of its dial.

When that happened, he'd have to rely on the electric turn and bank indicator, the pitot-static altimeter and vertical velocity indicator, and the backup "whiskey" compass-instrument flying at its most basic.

Airplanes and helicopters are usually equipped with a turn and bank indicator to provide their pilots with a continuous display of the lateral balance of their aircraft so the pilots can ensure coordinated flight.

In addition to an altimeter, compass, and an airspeed indicator, gliders are often equipped with a variometer, turn and bank indicator and an airband radio (transceiver), each of which may be required in some countries.
