With most of us pilots having dyslexia (5 out of 3 of us have it), are you really just going to trust your FMS typing abilities? How do you know that you are on track without doing a 10 minute past plot? Plotting and checking is what keeps us from having GNE's.
When the regulating agency comes looking for you after you have a GNE, what are you going to say "I am to good to follow the reg's or its my FMS's fault" And when they ask to see your Master Docs (FLT Plan, WX, Notams, Plotting Charts, ets.) that you are required to keep on file for 6 months, what are you going to say?
Come on guys how long does it possibly take?
