Types of Heading Indicator Errors

Heading indicators, like any other instrument, are prone to errors. Understanding these errors is crucial for pilots to ensure accurate navigation and safe flight. There are several types of heading indicator errors, including mechanical drift, apparent drift (precession), and other errors.

Mechanical Drift

Mechanical drift occurs due to the accumulation of friction within the heading indicator’s gimbal components.

This type of error is more common in older heading indicators, where worn bearings can increase the amount of friction-created drift.

Mechanical drift can cause the heading indicator to wander, leading to inaccurate readings. Regular maintenance and calibration can help minimize mechanical drift, ensuring that your heading indicator provides reliable information.

Apparent Drift (Precession)

Apparent drift, also known as precession, occurs due to the rotation of the Earth. The closer you are to the North or South Pole, the greater the hourly apparent drift.

At the equator, apparent drift is 0° per hour, while at the North Pole, it is 15° per hour.

This drift can accumulate over time, making it essential for pilots to correct for it regularly. By understanding and compensating for apparent drift, you can maintain accurate navigation throughout your flight.

Other Errors

Other errors that can affect heading indicators include human error, vacuum pump failure, and suction errors. Human error can occur if the pilot forgets to check gyro power and reset the heading indicator before take-off.

Vacuum pump failure can render the heading indicator inoperative, while suction errors can occur when the air flow over the gyro wheel is blocked or reduced.

Pilots must be aware of these potential errors and take corrective action to ensure accurate navigation. Regular checks and maintenance are key to preventing these issues and ensuring the reliability of your heading indicator.

Heading Indicator Errors Troubleshooting
