Note: This canopy selector program is intended as a guide. It is designed to be used to assist you in finding an appropriate model and size of Aerodyne canopy for your exit weight, experience level and expectations. Please remember that in no way can this selector replace professional, expert advice that is based upon first hand knowledge of your current experience, skill level and frame of reference.
Only training, experience, currency and a healthy body and mind can protect you from danger, bodily injury or worse. Regardless of your time in the sport, never hesitate to consult other, more experienced or knowledgeable individuals. They are often happy to help you try and make appropriate decisions.
At Aerodyne we recommend that you choose a canopy that you can land safely at your normal drop zone’s field elevation, in no wind, summer conditions utilizing a normal straight in approach and progressive flare. This is true both for the main and the reserve canopies.
Please note that this selector is based upon exit weight and International Standard Atmosphere (ISA) conditions. Exit weight is body weight + equipment + clothing. ISA conditions are at Mean Sea Level MSL with a temperature of 15 degrees Celcius and a pressure of 1013,25 HectoPascal. Canopy wing performance degrades at higher altitudes and with higher temperatures.
Aerodyne has developed an objective method to determine the degree of ellipticity of a canopy planform. We have dubbed this value the “planform factor” (Pf). A higher planform factor equates to a greater degree of ellipticity and will likely exhibit the associated characteristics. Typically an elliptical canopy is more equally pressurized for better flight performance and exhibits better flare capability. Similarly the toggle pressure is usually lighter and the turn response is quicker. While these observations are not absolute, they are often typical of those exhibited by canopies with more elliptical planforms.
