Feedback Issue 3/2011
The cover illustration is a cutaway of a PT6A-65. The PT6 engine is truly an icon of aviation both in Canada and worldwide. With close to 65 variants installed in dozens of aircraft types, It is arguably the most popular turbo prop engine ever produced. Since the 1960’s there have been somewhere around 36 000 PT6A engines produced accumulating 300 million flying hours. The PT6 can be found in almost every corner of the globe, from the North to South pole and every continent in between. It is utilized by more than 6500 operators worldwide and has made its manufacturer (Pratt and Whitney Canada) one of the forerunners in aerospace technology and paving the way for innovations both current and in concept.
(Statistics are taken from Pratt & Whitney’s website.)
