have been working for almost 2 years with these incompetent so called "pilots".
First of all, the majority of them can't even converse "casually" (simple english words) properly to their foreign colleagues in the cockpit.
The majority of locals only hold level 4 in the country, and even for that I feel most of them are not even worthy of level 4.
Yes of course, that particular local mentioned by your colleague is a typical example of a korean skipper.
They are probably also really PROUD of that because they probably think that they "exercise" caution or some other pilot related values of being conservative BUT the reality is not only the radio competency level is really poor but their general aviation knowledge is really appalling to say the least.
