“Private pilot here, and GPS is a nice luxury, but not a necessity if you know the basics.”
Who needs jammers when you have ME in the right seat. Girl friend was flying, I was checking something on the GPS, about 50 miles from destination. With turbulence, I hit a button unknowingly, I had set a waypoint but I didn’t REALIZE it. When we started down for the field 10 miles short of the real destination I found out that a GPS in the airplane is great but like you said you still need to pay attention to the basics.
GOD, I’m glad my CFI wasn’t there!
