When I mentioned notams I was thinking about pilot behavour in general. Errol is not generally notamed probably because it is already on the charts as a parachute zone. If anyone was speaking to Dundee, Perth, Leuchars or Scottish Info they would be told whether Errol was active.
Back in the old days (When we thought the world was still cooling down) notams were retrieved by fax and hung in the aero club. If you were out in the boondocks, only by talking to an agency could you get route info.
What does seem different nowadays is the proliferation of microlight types operating outside the flight school environment. Dare I say it the abbreviated course may also be a factor.
