Jack, you are correct. PT is Brazil. The ICAO ident series follows fairly closely the international radio ident series. It appears that a few countries have more iterations owing to the way they assign these tail numbers. Many use simply all letters and need more 4 letter combinations. I think Brazil and other countries with expanding general aviation fleets are now using numbers. Not so much for air carriers.

Question about aircraft registrations, but it is radio related.

What nation uses PT to begin a registration number? If it follows

radio call sign allocations it would be Brazil, just wondering if

aircraft registrations follow the same pattern.

Reason I ask, is I have an aircraft radio which is marked

with what looks like a registration beginning with PT.

Thanks in advance.
