On that stream of thought....
I wonder how many of the airline pilots today flying with A/P engaged, make it easy, can take a Jepp chart and plot two VOR radials to give an approximate fix in event of total FMS failure-and do it before they have gone charging through German Corner?
I wonder! When I mention to the newbies that we used to fly the B737-200 to the Canaries with only VOR DME (no groundspeed or time to station!) and ADF they look at me aghast! And we had no altitude alert even, the fuel planning and checks were all manual too! It taught us such a lot.
