But finding out if an airport runway is closed is easy, basic common sense and basic airmanship.
Problem solved then. All that has to happen is CASA revokes the license of any pilot who finds the current distribution of NOTAMs difficult, does not have common sense and is unable to define the requirements for basic airmanship. The incident that triggered the FAA response was the Air Canada flight that nearly landed on a taxiway full of jets at night in SFO. There was an issue with the NOTAM package where a closed runway was not so obvious. Its been a while since I have had to read NOTAMS but I don't recall runway closures always being at the top of the page. I am referring to the capital city airports as I haven't flown to a non-rpt regional airport for a long time.
