NOTAM in the U.K. is stuck in the dark ages! The only approved site is NATS and the content takes quite some time to travel through. The sidebar functions are useful in selecting what you need (Area brief, Narrow route etc), but the end results are an immediate put off and realistically leads to aviators skimming through which leads to errors.
SOP for my company is that NOTAM must be checked and almost all do this. The degree to which they are checked would vary IMHO due to the time it realistically takes to finger through. The way in which the NOTAM is written is backward. I’d much prefer straight text, to the point.
There is a very handy website called NOTAM info. It’s not approved but is exactly what is required! A graphic representation set upon a google maps base. A route can be checked in a fraction of the time it would on the official site and the dimensions understood on D/R/P areas etc. By clicking on the tabs throws up the actual NOTAM, a straight forward text would improve this feature further.
