I put a KNS-80 in my M20B last year. I was at the avionics shop with a bad radio that was going to cost a bundle. I was complaining of the lack of the ability to go direct legally and the shop owner told me he had a good used RNAV that would take care of the problem. Even though I use my yoke mounted Garmin 295 to go everywhere I go, I am able to use this as a backup and it works really well. Until I get the funds to upgrade my panal to an IFR Certified GPS, this will have to do and it I am very pleased with it. Cheap fix for nagging problem.

Hi, I also own a M20-B and like you, I have nothing but an Owners manual and have looked far and wide for some more numbers. So far I have found nothing. I even sent a note to Mooney about it and have yet to hear from them. It is my understanding that vintage birds like ours did not have to have the performance data published like they do now. Please correct me if I am wrong but I have been searching online for some performance software and so far all I have found is a weight and balance program. My airplane has almost 4,400 hours on it and I just got through with an annual and fuel tank repair job on both tanks. I have owned it almost three years and I love it. Elmer
