A Gyro Reminder That Will Save You Thousands of Dollars

September 2022

It wasn't long ago that I got a call from an operator who was having precession errors and failures to erect on his gyro. It didn't take long for me to figure out that the cause of his issue was the result of the gyro not being allowed enough time (20 minutes) to spool down before the aircraft was moved.

He stated his crew wasn't aware of this required spool-down time. This oversight unfortunately required a complete overhaul of the gyro, costing several thousand dollars.

We have written several articles and produced a few videos about the proper care and maintenance of a gyro. This may be a good time to share this information with all personnel tasked with aircraft movement/maintenance in your company. Below are links for your use. You can bookmark them for future reference.
