An
ICAO review
of 28000 incident / accident reports has found that over 70% of the
problems were caused by language.
ICAO standards now demand that all pilots flying
internationally and all air traffic controllers providing
services to international flights must have a minimum level of English.
This level of English is known as ICAO Operational Level
4.
