I don't think you gave the wrong impression.
with a view to using the Q400 type rating to do the required flight test to gain the full licence?
You MUST have a JAR or UK issued licence to apply. From what I can gather from your post you have a SA ATP? You wont even get past the application form if you don't have a UK/JAR issued licence. Therefore, you wouldn't be able to use the Q400 TR to gain the full licence as you wouldn't be eligible to do the type rating in the first place.
What I meant by 'training issue' is that if you are looking to get a licence issued that would be more appropriate to deal with a regular FTO.
