1. General Information
1.1 Introduction
The Bailey Release and Tow System has been used and refined since 1990 on the Bailey Moyes
Dragonfly for towing Hang Gliders, Ultralight Gliders and Light Sailplanes. This is more than a Release , it is a
complete System. Comprised of key elements protecting both the Tow Plane and the Craft being towed. The
Bridle and Slider, which is unique in the Dragonfly Aero-Towing community, allows more pitch control of the
Tow Plane during towing. This combined with proven application of the Safety Link in the Bridle protects the
maneuverability and structure of the Tow Plane.
1.2 Warnings, Cautions and Notes Explained:
WARNING: Denote items where Person Protective Equipment (PPE) is required when working on the
system components.
CAUTION: Denote items pertaining to safety that may be easily overlooked and may need double
checking.
NOTE: Items of particular interest or must be Inspected during routine maintenance and inspection.
1.3 Description of Bailey Release and Tow System
The Bailey Tow and Release System has a release similar to the “Schweizer Release” but also
incorporates special aspects such as the Bridle, Slider and Safety Links in key locations which afford the
maximum amount of maneuverability and safety to the tow plane & pilots of both craft. For this reason we
consider it a Complete System rather than just a release mechanism.
