I can remember when everyone was going to hang on to thier LORANS when the expensive GPS's came out and I see how many of those exist today installed in Helicopters. I have gone from Loran to GPS to GPS w moving map display in the same aircraft. The Trimble will be relegated to aviation trivia just like the Narco "Super Homer", ONI loran, and the fading Chadwich strobe. All excellent equipment when properly used just something better came out. We will learn, adapt, chat fondly about the old stuff remember the good and bad, But you will find yourself in the Air going Wow glad I do not have the old "blank" anymore this is a huge improvment.
