The heading indicator (HI), also known as a directional gyro[1] (DG) or direction indicator (DI), [2][3][4][5] is a flight instrument used in an aircraft to inform the pilot of the aircraft's heading.

2022年5月9日 · The heading indicator allows the pilot to see, at-a-glance, the direction the aircraft’s nose (or ‘longitudinal axis’ if you want to be all ‘technical’) is pointing. Reading the instrument will tell you your magnetic heading.

2023年7月27日 · What is a heading indicator in an aircraft? The heading indicator (HI) is a primary flight instrument that is part of the basic aviation “six pack.” You may also hear this instrument referred to as the Directional Gyro (DG) or Directional Indicator (DI).

The heading indicator is an instrument used to determine the aircraft heading of a plane, used by the pilot to navigate.

The magnetic compass is the primary indicator of heading information in an aircraft, and knowing your heading is essential in order to find your route. However, the magnetic compass is inaccurate due to acceleration and turning errors.

2021年12月6日 · The Heading Indicator (HI), also referred to as the Direction Indicator (DI) or Directional Gyro (DG), is the primary horizontal direction indicator in the aircraft. The HI suffers from drift errors and needs to be periodically corrected to the correct heading by using the magnetic compass.

2023年6月2日 · The heading indicator (HI), also known as the directional gyro (DG) or direction indicator (DI), is an essential tool for accurate aircraft navigation. It offers a stable, reliable alternative to the magnetic compass, making it vital for maintaining heading, especially in low-visibility conditions.

2019年9月6日 · Directional gyros, also called heading indicators or direction indicators, are the fastest moving component in a piston-powered aircraft. They can spin at up to 24,000 rpm, and are among a plane’s most critical systems.

2024年4月26日 · The heading indicator is a fundamental flight instrument found in aircraft cockpits, providing pilots with essential directional information. It integrates seamlessly with other navigation instruments, allowing for enhanced situational awareness and accurate navigation.

2023年8月1日 · The heading indicator (also known as a gyro) is a critical instrument in aircraft navigation, providing pilots with accurate information about the aircraft's direction of travel. Accurate information is essential for maintaining straight and level flight paths, avoiding collisions, and ensuring safe navigation during flights.
