Since the subjective performance increase (especially in climb) seemed too good to be true, I went to www.flightaware.com and used the historic flight data to calculate as objectively as possible my average climb rates with and without strakes and Speed Covers. (Since there is no way of accurately estimating the winds aloft for each flight, I did not try to use this method to calculate average speed increases.) I always use the same cruise climb power setting (35 inches and 1900 RPM) and most of …

In furthering the improved efficiency of the propeller versions of the twin Cessna’s, Premiere is testing and designing additional refinements to further reduce drag, increase lift and provide similar gains are our proved popular Speed Covers. Stay tuned as we are not close to being finished turning over the rocks….
In addition, Premiere is involved in the final certification of our patented impeller cooling Speed Covers for the Cessna CJ Citation series business jets. The dual function of these covers is going to set a new standard for expected and delivered value in the STC aircraft refinement standards of the industry….
First and foremost, I wanted to thank you all who have supported our Speed Covers in your comments suggestions opinions. It has been a good journey and we are ready to expand our development into other needed drag reduction/lift increase methods and techniques in 2016. In 2016, we all are interested in improved avionics and flight control systems and many of our planes are getting retrofitted with new gear. As for engines, not much has changed beyond the engine monitor but for true utility and efficiency…
