Dividing time between the UK and the US
I'm thinking about flying in the US about twice a year, mainly for hour building. If I apply for an FAA licence based on my JAR licence would it only be valid for a short time e.g. the duration of the trip? I guess my question is, do I have to re-apply for an FAA certificate every time I want to fly in the US or would it be worth my while gaining an FAA PPL as well as my JAR one??
