What is an attitude direction indicator?

The attitude direction indicator (ADI) presents the pitch and bank of the aircraft relative to a depiction of the horizon. In general a so-called inside-out frame of reference is used (fixed airplane symbol against a moving horizon).

Why is the attitude indicator important?

The attitude indicator on an airplane is very important. It informs the pilot of the orientation of the aircraft relative to the horizon, so it must be correct at all times regardless of the plane’s movements.

What is the direction indicator?

: a compass that assists an airplane pilot in flying a predetermined course by direct reading and comparison of two indicators one of which is set for the desired heading while the other shows the actual heading so that when the two indicators point alike the airplane is flying the desired course.

What is the attitude of an aircraft?

[Figure 3-1] Attitude is the angular difference measured between an airplane’s axis and the line of the Earth’s horizon. Pitch attitude is the angle formed by the longitudinal axis, and bank attitude is the angle formed by the lateral axis.

Which is the north direction?

North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to East and West. North is a noun, adjective, or adverb indicating direction or geography.

What is a compass indicator called?

It is sometimes referred to by its older names, the directional gyro or DG, and also (UK usage) direction indicator or DI.

What controls the attitude of an aircraft?

For VFR flying, the attitude control instrument is the horizon outside the windshield. The power control instrument is the tachometer or manifold pressure. Attitude flying requires intimate knowledge of the four fundamental flight maneuvers, climbs, descents, turns, and straight and level flight.

What does the attitude indicator display Mcq?

Explanation: The attitude indicator displays the aircraft’s relation to the horizon.

How is the attitude and heading indicator mounted?

The gyro in a heading indicator is mounted in a double gimbal, as in an attitude indicator, but its spin axis is horizontal permitting sensing of rotation about the vertical axis of the aircraft. A knob on the front of the instrument, below the dial, can be pushed in to engage the gimbals.
