What is the difference between a narrow route brief and a full plot of all NOTAMs?
Using the free AIS website, you can obtain a narrow route brief which is a filtered version of entire PIB leaving you with around 3 or 4 pages of A4. The disadvantage of this system is you still need to read and fully understand the text and it only applies to flying in a straight line. Plotting the NOTAMs from a full PIB graphically on to a map allows you to gauge the general area you wish to fly. You have a better appreciation of how close the NOTAMs may be to you flight and which ones are irrelevant.
