Yes you can do your PPL(A) on a TMG. Just means that initial issue is with a TMG Class rating. We do the instrument appreciation on our TB9 (SEP) and so it makes sense to get the SEP Class rating as well. The IAA have appointed an examiner so there is no problem with the skill test.
As a general point, the motorfalke cruises at 75kts (140kph) and so is not far behind a C152 or Rallye and has the added advantage of being capable of soaring engine off (lower hire rate!).
If you want to get a PPL(A) with SEP Class rating, the best method is to do the PPL(A) on TMG and then add the SEP Class rating. Overall cost will be less than the PPL(A) on SEP and you will have better handling skills to boot!
We operate mid week as well as weekends and Bank holidays so drop in for a chat.
