Newbie Here: What are the different Aviation Authorities in the world?

[dingdongbubble]

Hello

I am a high schooler and I am looking into a career in aviation. I ahve a question here. Can you list out all the different aviation authorities in the whole world like the JAA and FAA. I understand that the FAA is for the USA and the JAA is for Europe and some non EU countries use JAA as well. Can you tell me which authority's license will I ahveto get for flying in the following countries:
a. Canada
b. Iran
c. Iraq
d. United Arab Emirates

What happens if I get a license from lets say the FAA and now I want to fly in the UAE and move there and get a prmanent job with Emirates or Etihad?

hmm anyone? I think I kind f figured out that each country has their own flight authority with its own rules and stuff. The JAA is a unified authority for lots of countries.

How long does a license conversion take?

Cant you be licensed by more than one authority at once? Like cant I have a JAA and FAA license at he same time xactly like we can have a driving license from multiple authorities in each different country.

Most countries have their own licensing authorities. The "biggies" are FAA/JAR ops licences and these entitle the holder to fly in/out world-wide control authority zones, as do most of the internationally recognised licences. You may hold as many licences as you wish although that would be a lot of extra work. If you already hold an officially recognised ATPL/CPL and you wish to gain or transfer to another licence type, it usually requires a minimum of an air law exam for the new state and sometimes a short sim/flight test. To fly for an airline in the M.E., FAA or JAR ops are acceptable but each airline will exam you subject to their own country's regulations; eg Saudi Arabia has its own licensing authority which is based on the FAA rules but has specific differences. I recommend you concentrate on getting licensed in your own country first; that will set you on your way.
