Airliners have, depending in which country they are registrated, national registrations. But what for they are standing for?
E.g. N for US Airliners means something like national, D- for German Airliners means Deutschland (which is the German name for Germany), G- for UK Airliners maybe Great Britain.
But what means B- for Chinese Airliners, or HB- for swiss planes?

I know there´s a heritage for the country prefixes. But a random one. There´s no logic and in many cases no meaning behind the country prefix on regs. If so, why "5N-" for Nigeria, "9V-" for Singapore or "VH-" for Australia? And why has Brazil two prefixes, "PP-" and "PT-"?
"D-", "I-", or "F" are clear, but why has Spain "EC-" then, when logically "E-" would be more appropriate? And why has Britain a "G-", when "GB-" would make more sense.
I ask myself why these prefixes haven´t been changed to the one´s used for cars long time ago.

Well, I wouldn't bet.
Actually, as you say, some registrations seem to be "logical":
OE-Austria (The german name Österreich, being orthographically correct to add an "e" in substitution of a diaeresis: Oesterreich)
EC-Spain (the "e" for "España", the "c" for "civil")
In Switzerland, maybe the H has something to do with "Helvetia", the name of the country being "Confédération Helvetique" in French. Since it has a Federal kind of administrative distribution, maybe the B stands for some kind of "Bundes-whatever", which is the german word for federal.
I assume that given some logical two letter combinations, the number of possibilities is quite reduced, thus just giving "free" combinations of two letters or one letter+one number, but I am just speculating. Nevertheless, I assume that two digit combinations are not enough for giving each country a "logical" abbreviation.

Hibernia has nothing to do with Switzerland..... it's the name of a major oil field in Newfoundland (Canada). Switzerland's official title is neither French, German, Italian nor Rumantsch, but latin: Confederatio Helvetica... Helvetica being the ancient name of the present area of switzerland.
On a separate note, I remember reading once that some countries' registration codes are the initials of aviation pioneers from the country.

if that would be right, the US should have at least a dozen different prefixes...
Not neccessarily. The US registrations are N followed by numbers followed by letters, usually the carriers 2 letter code for the majors. Therefore it is possible that you can have N695AA and N695UA. The possibilities are virtually unlimited.

OK, OH-LZA, I assume they are progressively getting rid of the RA- registration, which otherwise is logical. At an end, only Russia should remain with RA-, being normal each country having an own code.
BTW, Na, do not mix Country (=independent politically and administrative state with frontiers and political personality) with State (=administrative unit of a federally organized country, like Brazil, USA, Germany -although they call them "Land" in singular or "Länder" in plural- etc)
California, Massachussets, Iowa, Ohio, Oregon, New Mexico, Washington, Illinois, Florida, etc., are not comparable to "post-USSR" Azerbaitjan, Turkmenistan, Estonia, Lithuania, Latvia, etc.

First, Brazil has 3 ICAO country codes (PP, PT and PR). As for the PH for The Netherlands. This probably is explainable. before "PH" the Dutch country code was H. However they changed it to "PH". The meaning of the "P" is open for debate. Either they used a "P" to point to Plesman (founder of KLM) or it's due to "Poste Hollande" (as explained by Flanor in a previous discussion).
Anyway it's my believe that the initial country codes have been determined around 1929 at an ICAN convention (as the ICAO didn't even exist at the time). Given the fact that aviation was dominated by the military and postal services I think that one of these two is the answer.

Use of the N registration, assuming the standard six-character identifier, theoretically gives you 676,000 aircraft IDs. That's about 50 times the total world airliner fleet.
Of course it also limits you to 1,000 aircraft if you maintain a fixed two-letter suffix identifying your airline. But since it's only American which is even close to that problem, it hardly matters. Besides it's easy to overcome; just extend the registration to a four-digit numerical section.
