if you're converting an ICAO ATPL and have more than 1500 hours on multi-pilot aircraft you can, with more than 500 hours on type, take your ATPL skills test on type at an approved TRTO without any further training. If you have less than 500 hours on type you can complete training 'as required' then do the skills test on type. For the A320 this means doing the license issue flight test in the sim at an approved TRTO. My guess is that this is what flight booster is looking for. Try GCAT or CTC.
