1) Draw lines on chart and write-up a full PLOG as per training
2) Tune in a VOR/NDB and use that instead
3) Feature crawl (not necessarily along the line I drew on the map, but always aware where it is if needed).
I know feature-crawling isn't the 'correct' way to do it. Accurate dead-reckoning nav must be very satisfying - just looking out the window after X minutes and seeing exactly what one expects, but when unfamiliar with the area, I want to see and identify everything I pass over so that if/when I have to turn around, I know exactly what I'm likely to see on the way home. I get very uneasy if I don't know EXACTLY where I am all the time, even if I'm sure I'm on track. I suppose that's why I like the VOR/DME combination.
