Seems to me, as a broad general proposition: 1) Consistent use of North up is better for longer-term navigation or course planning, when you're zoomed out on the map and asking, "Where am I in the big picture?" or "What course should I take to reach a given (distant) destination?" (or to avoid things I should avoid). Better chance of identifying major landmarks (lakes, mountain peaks) correctly and understanding the broad situation. 2) Track up better for short-term maneuvering, when you're asking "What should I be looking for, and what maneuver do I have to make, in the next few minutes?" Excellent analysis. This is why I use both sectional/Low Alt chart and GPS. I always fold the map(s) to a reasonable sized rectangle to get the big picture enroute, alwyas North Up. The GPS is Track Up but a much smaller area than the sectiona and/or Low Alt. chart. I can always tilt the chart as needed if I want a track relative view, no biggie. Situational awareness is the key... whatever works go for it. But I never fly without charts, even though I do love the GPS, I still follow my progress on the chart. |
