Beammeup,
What scale map are you using?
When I started DR nav, my instructor insisted I use a 1/2 mill.map, which I detested as it didn't show enough detail. When I got my licence, I did all my nav. using a 1/4 mill.
Now, 3 years later, I'm begining to realise that he was right. The 1/4 mill shows too much detail and its easy to get confused. The 1/4 mill is great for showing passenger where they are, but if all you can see from the air is towns and larger roads, then use a map that only shows them.
Comments??
