I understand that you feel very passionate about this.
But please stop commenting on issues that you have only a little knowledge of.
No one is going to be restricted from flying in four months time for not being ICAO compliant.
You are inadvertently creating a safety issue when you are worrying crews about the consequences of not being compliant.
Those who are tested below level four will be assisted in gaining the appropriate qualifications and not just hung out to dry.
If you have time, go and visit the ICAO site for language testing and when you have digested all of that and then looked through all the nuances and exemptions that can and will be issued, then maybe you can start commenting on the issue at hand.
In the meantime, I would kindly suggest that you refrain from scaremongering your colleagues.
Thanks
