How Does a Turn Coordinator Work?
This device features a simple yet effective mechanism, consisting of a ball that moves within a curved glass tube. Continue reading as we dive deeper into its inner workings.
Construction and operation
Inside this instrument, a gyro spins rapidly, aligned with the long axis of the aircraft. This distinct mounting allows it to accurately gauge both your rate of roll and rate of turn. When you initiate a turn or tilt in the plane, the gyro reacts instantly due to its design based on precession principles. This reaction causes an indication needle or an airplane symbol on a compass card to move proportionately, providing visual evidence of your turn's pace.
Additionally incorporated into this indicates coordination; there's also an intuitive ball within a curved glass tube that helps monitor slipping or skidding during turns. If you're executing a coordinated turn – turning without any sliding sideways – then this ball remains centered conveniently presenting real-time feedback about your maneuvering techniques. Rates of slipping and skidding are showcased when this ball moves progressively towards either side of the tube.
Standard rate turn
To fly safely and efficiently, it's important for pilots to understand standard rate turns. A standard rate turn is a turn made at a constant rate of three degrees per second. This means that the aircraft will complete a full 360-degree turn in two minutes. By maintaining this, you can ensure smooth and coordinated flight. When making a standard rate turn, simply keep the rotating needle or aircraft symbol on the compass card aligned with the desired mark or heading indication.
By practicing standard rate turns, you'll develop better control over your aircraft's movements and reduce the risk of slips and skids during turns.
Avoiding and correcting slips and skids
To avoid slips and skids during turns, follow these steps:
- Keep the ball in the center: When making a turn, ensure that the ball stays in the center of the curved glass tube. This indicates a coordinated turn and ensures that you are not slipping or skidding.
- Adjust bank angle: If you notice the ball moving to one side of the tube, it means you are slipping. To correct this, reduce your bank angle slightly until the ball returns to the center.
- Adjust rudder input: If the ball moves to the other side of the tube, indicating a skid, increase your bank angle slightly and apply more rudder pressure on the same side as the ball to correct for it.
- Pay attention to rate of roll: If you notice excessive or abrupt rolling movements while turning, adjust your control inputs to maintain a smooth and controlled roll.
- Practice coordinated turns: Regular practice is key to developing good piloting techniques. Practice making coordinated turns by keeping an eye on both rate of turn and coordination indicators.
Coordinating turns
Coordinating turns is essential for maintaining control and stability during flight. Here are some key tips for coordinating turns:
- Apply rudder pressure in the direction of the deflected ball.
- Keep an eye on the instrument to determine the coordination of your turn.
- Adjust your bank angle as necessary to ensure a coordinated turn.
- Use smooth and gentle inputs to maintain coordination throughout your turns.
Turn Coordinator Preflight Actions
Before every flight, it is crucial to take preflight actions to ensure everything is functioning properly and providing accurate readings.
Checking for proper functioning
Ensure that the gyro is operational and that all indicators are working correctly. By doing so, pilots can rely on this important instrument to provide accurate readings of their rate of turn and coordination during flight. Regular checking helps pilots maintain control over their aircraft and prevent slips or skids, reducing the risk of accidents or loss of control.
Ensuring accurate readings
Regularly check and calibrate everything. Make sure the gyro is working properly by checking for any abnormal movements or noises. Additionally, verify that the ball is moving freely within its curved glass tube without any obstructions or sticking points. If you notice any issues, have the instrument inspected and repaired by a qualified technician before flying.

Turn Coordinator vs Turn and Slip Indicator
These two instruments, although similar, have unique characteristics that set them apart.
The Turn Indicator is primarily designed to showcase the rate of turn in an aircraft. It relies on a mechanical gyroscope for its operation, spinning it into motion due to the air pressure difference created by an engine vacuum system.
On the other hand, the Turn Coordinator not only displays the rate of change in direction but also provides information about roll or bank angle during turning maneuvers. Unlike its counterpart, this instrument functions through electrical power supplied to its gyroscope. This distinction allows it to respond quicker and more accurately than a standard turn indicator under certain flight conditions such as steep turns or turbulence.
Below is a more simplified comparison of the two flight instruments:
| Feature | Turn Indicator | Turn Coordinator |
|---|---|---|
| Primary Function | Rate of Turn | Rate of Turn & Roll Angle |
| Gyroscope Mechanism | Mechanical Gyroscope | Electrical Gyroscope |
| Operation | Engine Vacuum System | Electrical Power |

FAQs
Q: What is the purpose of a turn coordinator in aviation?
A: It is an instrument that provides pilots with information about the aircraft's movement and coordination during maneuvers. It helps them maintain control and avoid slips or skids.
Q: How does it prevent slips and skids?
A: By monitoring the position of a ball within a curved glass tube, pilots can apply appropriate rudder pressure to counteract slips and skids, ensuring stable flight.
Q: What do the indications mean?
A: When the ball moves towards the outside of the turn, it indicates a slip, meaning the aircraft is turning too shallowly. Conversely, when the ball moves towards the inside of the turn, it signals a skid, indicating the aircraft is turning too sharply.
Q: Why is coordinated flight important?
A: Coordinated flight ensures that the aircraft's lift and thrust are used efficiently during turns, promoting stability and control. The turn coordinator helps pilots maintain coordinated flight by providing real-time feedback on their turns, allowing them to adjust rudder pressure accordingly to keep the flight path aligned and prevent loss of control.
Q: How can I recognize if my aircraft is experiencing a slip or a skid?
A: A slip occurs when the aircraft's nose points toward the inside of a turn, while a skid occurs when the nose points towards the outside of a turn. Pilots can recognize these by observing their body position relative to the horizon and using their peripheral vision to assess any sideways motion.
