New gyroplane design standards improve flight safety

As a direct result of our research, there have been no deaths in a gyroplane accident in the UK since 2009. Previously, gyroplanes (also known as autogyros) had a questionable safety record. Following fifteen years of comprehensive studies, researchers recommended innovative new design standards to the Civil Aviation Authority.

‌These recommendations led to the introduction of new civil airworthiness requirements in the UK, subsequently adopted by Australia and Canada. The implementation of these revised regulations has forced gyroplane manufacturers to change their designs. Close to 2000 machines have been produced since this design change, revolutionising gyroplane safety worldwide.

Gyroplane: Original straight keel. When the propeller size increased it was necessary to raise the height of the propeller to avoid the keel – this introduced instability.

Gyroplane: Dropped/stepped keel introduced as a result of the University of Glasgow recommendations to CAA, adopted in BCAR Section T. The dropped keel enables the propeller to remain low, maintaining stability.
