AAhhh, nothing changes here it seems.
GPS.....Hmmmmm is it accurate?.... is it reliable?
I have only been flying IFR since we used the radio range and the last time i flew IFR was as a crew member in a 767, it didn't have GPS nor INS..it had RNS.
However for me I like and trust GPS, far more than ADF, VOR etc.
But then what do I know about flying?
