guidance SIGNS lateral spaces/borders
Hi,
could someone give his comments about guidance signs inside airport, airside?
I think that:
e.g. inside "Figure N-2G. No-entry sign", I have to understand that the 2 lateral spaces "H" are as "at least" and not as precise measures;
the same is for e.g. "Figure N-3. Sign dimensions" part A "H/2" as "at least" and part B "H" as "at least".
This interpretation is as per ICAO A.D.M part 4 (search for "at least"), para 12.2.6, "...The width is determined by the overall length of the inscription, to which must be added a border of at least 0.5 times the inscription height at either end of the sign.". The same info is always included in all the editions of UK CAP168.
A different interpretation could be that the manufacturer has to procude any single lenght of structures of the signs. In my opinion this interpretation is not technically feasable for the producer, mainly for lighted signs producer.
