Is there minimum proficiency for pilots in Australia.
For our international medical graduates they need to meet a minimum proficiency
There are several English proficiency tests. Using the IELTS they need overall 7.5 and a minimum 7.0 in listening, reading, writing, speaking. Australian, UK, Canada, NZ, Ireland, South African graduates are exempt from sitting the test. Surprisingly US is not
There are other approved tests but they are harmonised so taking one rather than another is not better or worse.
There is English and there is Aviation English, case in point back in the eighties I was in Sydney Tower giving a takeoff clearance to China Air that involved a heading change at 6 DME:
Me “China Air 112, at 6 DME turn left heading 250, clear for take off”
China Air “Clear for Takeoff”
I detected some confusion in the read back
Me “China Air 112, confirm at 6 DME turn left heading 250”
China Air 112 “what’s DME”
Me “China Air 112, do you have DME, distance measuring equipment”
China Air 112 “yes, we have a ruler”
Me “China Air 112, cancel previous clearance, maintain runway heading, clear for takeoff”
In those days crew didn’t speak much English, and often had a third member on the deck translating, and they were not always fluid in aviation English.
Later in my career I had the pleasure of working Bankstown tower where we had a lot of foreign students learning to fly, again you could normally detect an issue in the readback where the message wasn’t clear to the student, even when using standard non localised phraseology.
