I am well aware of the reason for the existance of ATIS, which was not mentioned specifically in the NOTAL which you correctly pointed out but, in Paragaph 2 of the NOTAL states "The purpose of this NOTAL is to draw the atention of aerodrome Licensees to the need to ensure regular Meteorological observations are made during periods appropriate to the needs of public transport flights using the airport"
It then mentions in paragraph 4 "The authority strongly recommends that all aerodrome Licensees & providers of ATC services where appropriate review the proceedures for the provision & dissemination of meteorological observations at their aerodromes". which if I am not wrong could mean the use of ATIS, NOTAM, RT.
I mentioned the existance of this document to try & explain why these so called this & that warnings may arise at BRS, giving rise to the title of this thread in the begining "BRI warning this & that"
