Study Notes
Gyroscopic Instruments
- Gyroscopes form the crux of gyroscopic instruments, with properties of rigidity in space and precession, allowing them to remain stable in their plane of rotation, resisting external forces.
- The mechanical anatomy of gyroscopes is vital, with a rotor spun at high speed, facilitating their rigidity in space.
Turn Coordinator
- The turn coordinator indicates the rate of turn and confirms the aircraft's roll information, providing immediate feedback for smooth and balanced maneuvers.
- It consists of a gyro mounted at an angle, enabling it to sense both roll and yaw.
Heading Indicator (Directional Gyro)
- The heading indicator displays the aircraft's current heading relative to magnetic north, unaffected by the aircraft's turn or acceleration.
- It is powered either pneumatically or electrically and must be periodically adjusted to account for precession, aligning it with the magnetic compass.
Attitude Indicator (Artificial Horizon)
- The attitude indicator displays a picture of the aircraft in relation to the horizon, telling the pilot whether the wings are level and if the aircraft is climbing or descending.
- The gyro in the attitude indicator is mounted in a horizontal plane, relying on rigidity in space to provide a constant horizon reference.
Compass Errors
- Magnetic variation is the angular difference between true north and magnetic north, affecting navigation and requiring correction.
- Magnetic deviation is an error specific to the aircraft, caused by local magnetic fields created by its components and electrical systems.
- Magnetic dip is an error caused by the Earth's magnetic field lines being inclined downwards towards the poles, affecting the compass as the aircraft changes latitude or accelerates/decelerates.
Correcting Compass Errors
- "Swinging the compass" is a process used to measure and mitigate magnetic deviation, involving a methodical dance of aligning the aircraft on known headings and noting disparities on a deviation card.
- Correcting for compass errors is crucial for precise navigation and safety.
