If you are mathematically challenged, or could not be bothered with pfaffing with old school whirly-wheel thingies, then this is a holiday gift you must put on your list!
The predecessor of the CX3 was the CX2, which was developed in the 1990’s and was probably the first electronic calculating device designed solely for the aviation market. Personally, I do not think I would have made it through CAA theoretical exams without it, but it is also an invaluable tool for the general aviation pilot. So often, every day calculations such as cloud base, fuel endurance or density altitude are either guessed, or assumed, simply because it seems such a chore. The new ASA CX3 can do just about every calculation that you would need for a safe and well-planned flight.
So what is so exciting about the new arrival?
UPDATE: The CX2 and CX3 are now approved for SA CAA CPL and ATPL exams! However, there are conditions, and not permitted for PPL exams, so please check out the AIC here.
