That is correct, 'got the horn'
I went into CAA a couple of years ago, ambushed John Parker at his desk, got the bit of paper filled out.......took him five minutes of looking at my logbook..........do it at the end of the day, makes it quicker!
then I sent in the 'fit and proper person thingy, paid $50, and the D cat was put on my licence with my B cat.
The good folk at CAA did it quickly and easliy. The coffee's quite good too!
However IF you dont have a current C or B Cat, then the D Cat is an INITIAL issue instructor rating........
I have put a couple of D Cats through a few years ago.
Loco as always..........
