Product Description Fokker F27-500 Friendship Gyroscope A Gyroscope is a device for measuring or maintaining the orientation of the aircraft. This beautiful gyroscope has served a Fokker F27-500 aircraft for many years and has been replaced with a newer version as the technology advanced. Some of those F-27’s where these gyroscope are coming from are still flying today. We have installed a hidden LED lamp inside the device, it can be turned on easily with a small cockpit avionics switch. This is a genuine piece of aviation history.
