Perhaps it is Kemble's experience that the sort of people that pitch up out of hours, don't read the NOTAMS either
Maybe it's just me that thinks the NOTAM poimulgation is the most unintuitive and use unfriendly IT system I've come across.
If we seriously want to avoid issues, due to pilots missing NOTAMs, then sorting out the AIS website would be a great start.
Having to use an archaic language such as "DCT GWC DCT SAM DCT OCK" for a narrow route brief to cover the area I'm flying in is just asking for mistakes.
I don't think it would take much to add a "point and click" interface so that pilots can point at where they're flying to / from and the NOTAMs automagically appear. I bet it would lead to tangibly fewer airspace infrigements right there.
