Nature is full of clues to help you find your way – if you know where to look. Stuart Heritage lets go of the GPS to learn the art of natural navigation from pioneer Tristan Gooley

[...] How to navigate in a city

Look for satellite dishes. They all point towards the equator. In London, that is roughly south-southeast.

Find an 'invisible handrail' and use it to remember your bearings. In the countryside, this might be a river. In a city, it could be a main road.

Look at a tree. Do the branches point a certain way? That's probably south. Are the leaves on those branches smaller than the leaves on the opposite side? That's definitely south.

Use the sun. It rises in the east, sets in the west and moves through the southern sky, giving you a very basic compass.

Need to get home? Head against the flow of people at the start of the day or with the flow at the end and you are pretty much guaranteed to find a station.

    Sorry, you still have no idea what you're talking about. You're talking about the use of VFR (visual flight rules) rather than instrumental flight rules. Within VFR, there are a number of techniques.

    Navigation by visual landmarks etc. is known as "pilotage." Navigation WITHOUT visual landmarks is known as "dead reckoning." In the latter, you base estimated position on measurements of travel alone -- mostly speed and elapsed time, but corrections can be attempted on measures conditions too. Originally the term was developed for ships at sea with no visible landmarks -- so speed/direction and elapsed time were the main factors used for dead reckoning, but known ocean currents, wind conditions, etc. could be factored in as correction factors for the estimate.

    Looking around at landmarks, terrain, etc. (which you referenced in previous posts here) is pretty much the OPPOSITE of dead reckoning. Seriously... Look up any definition.
