My four letter code is RPVT but I also have a question regarding ICAO codes. I vaguely know that the first letter is a continent or region, as in E for Europe. But my question is this: does Antarctica have any ICAO codes? Aircraft land there and have to log flight plans. If not, what is the minimum criteria, control tower/radio frequency/navigation beacon? I guess a permanent runway would be a start, as well.
I will answer you as follows:-
RPVT is Tagbilaran airport that serves Tagbilaran City,Bohol Province, in the Philippines. It is rated as a principal class1 airport.
With regards to Antarctica, there is a special agreement that only allows flights by air there to accredited research stations, of which many countries have there. Britain has four such landing fields for its research stations:-
Fossil Bluff, George VI Sound....................Skiway
Halley Station, Brunt Ice Shelf..................Skiway
Rothera Research Station, Rothera Point.....Airdrome
Sky Blue, Ellesmere Land..........................Airdrome
My next clue is
