I’d argue not learning / using the technology that’s readily available and far more accurate to be a greater issue than ditching the whizz wheel. The amount of people I’ve flown with who have no idea how to tune a beacon or use the gps is worrying! The equipment will save your ass far more than the whizz wheel! Of course solid S.A is key but when it gets muddled the instruments or GPS will save you a lot more than anything else. Worst case call ATC!!
