You're right Tom, this was really only meant as a minimal backup, i know many pilots who don't even fly higher than 3000ft, I know some who use the ADS-B Exchange Watch app, to be prepared for the rough environment but surely VFR depends on good airspace observation anyway! Was really just meant as an emergency backup when you don't have your stratux in your pocket or flying with minimal equipment, stay healthy & always happy landings, and Tim thanks for your great work!
