IATA/ICAO - The industry takes what it wants from their regualtions and blatantly ignore other parts.....
I have a perfect example:
AHM630 14.6.1.2 - Thunderstorm/Lightning
Stop/Suspend Activities - Lightning Activity is detected within 5km (3 miles) of your operation...
How many times has your Handling Agent and/or Airport Authority imposed/ignored this instruction?
I could give loads more examples but we all know them....
