You can even have the terrain displayed under your map.
You can make equivalent of ILS approaches to airports that have no radio guidance.
I haven’t flown for quite a while either. I flew a T210 which had 5 hrs fuel. I always said I had 4 hrs for the flight plan. I never planned legs further than 4 hrs.
I was never worried about running out of fuel either.
That is the most avoidable accident there is.
The other thing you NEVER want to hear a controller say is “Declare your intentions”! That can only mean that you’ve not communicated with him or her in a manner they can understand and they take that very poorly!
The happiest words to me are “You’re clear of my airspace, squawk 1200 and resume normal navigation”!
