Feature tracking works OK when there is good visibility. It falls down when the vis is poor or it’s raining etc, not uncommon in the UK. Unfortunately it can become a habit because nav is rarely taught in poor vis.
You have to have a systematic technique that works in all conditions ( and when the GPS goes belly up ). It is based on the idea that if you accurately steer a planned heading for a given time to a recognisable feature, you then have a basis for working out a correction which will return you to track, and when you regain track, an alteration which then maintain the track. This system corrects for errors in the forecast wind. It doesn’t however correct for inaccurate steering of the headings, a much more common fault.
