Use of GPS whilst hour building

KNS 80 was very good in its day and still makes a useful DME for those occasions when you might need one.

I have held a FAAIR since 2002 and a EASA PPL/IR since 2011.

I still fire up the Narco RNAV equivalent of the KNS 80 (NS 800) every time I fly both IFR or VFR for anything but a local bimble.

It all forms part of my quadruple redundancy of navigational avionics which means I won't find myself in the position of G the Es dud battery student.

I also draw blue lines on the chart, use a stopwatch and look over the side from time to time.

It has a lot to recommend it

But I use the 430W for IFR stuff and SD on iPad for VFR from choice, but both the NS800 and the 430W can be coupled to the auto pilot.
