SafeTurn Portable Turn Coordinator

​

Technical Specifications / Operation
Last updated July 13, 2025

 

The RADIANT SafeTurn is designed to show simultaneous turn (yaw) and bank (roll) information. Yaw information is derived from a solid state gyroscope. Roll information is derived from a solid state accelerometer.

 

All of this information is presented digitally and graphically on a single vivid LCD screen, inside a portable case.

 

SafeTurn has an internal USB rechargeable battery. SafeTurn will provide approximately 4 hours of battery life per charge. SafeTurn may be used while it is charging.

 

This instrument will automatically stabilize and provide the pilot with roll and yaw information regardless of initial position, acceleration, or attitude.
