Rod1 & GBZ...."Not GPS but the number of times I've flown abeam the LIC NDB and watched GA traffic pass its overhead at similar levels but seemingly oblivious to each other's presence is quite alarming"
I'm quite astonished to see the amount of traffic that uses airfields as navigational waypoints by flying directly over them at 2050' (estimated!). Common sense suggests to me that flying directly over NDB's/VOR's/VRP's and airfields is best avoided, particularly at around 2000'. Why don't pilots navigate with some sort of offset from the feature that they're using ? Actually, thinking about it, the more pilots who navigate this way, the safer it is for me as I avoid such hotspots!
