Pretty accurate there Bernie, just a few corrections on the conversion:
- To have your flight radio endorsement carry over you will have to do an English language proficiency test. Not hard to do, but probably cost about another $100 or so.
- To convert the Nav endorsement across you will need to meet the RPL experience requirements. This means 5 hours total solo Nav (most RA cross country endorsements only have 2 hours), and also 2 hours instrument flying.
- You will have to do a medical for it as well, your choices are either the RAMPC, or a class 2 medical. The RAMPC will limit you to only one passenger, and operations below 10 000ft. If you meet the standard, I personally would just get the class 2.
- You don't actually need a PPL to operate in CTA/CTR, these are endorsements that can be added on to your RPL. You are correct that you are limited to 1500kg MTOW, however you can do endorsements such as CSU, retrac etc, as well as aerobatics and a few other flight activity endorsements.
As stated above, the GA AFR (aeroplane flight review) will do your RA BFR, but it doesn't work the other way around at the moment.
