Ok, coming to think about it, I may have underestimated the number of combinations. Ignore me

actually you may have a point, I think we need reservations for US so that we dont run out of combinations (and have it realistic), which unless an airline has more than 9999 aircraft in their fleet they wont run out of combinations, now as for the rest of the world you have a point. Some countries like France or Germany probably wont run our of combinations, countries like Japan, China, and Britain etc. that have allot of airlines in them, may eventually run out (although unlikely still a possibility) so perhaps have the same system as in US everywhere except replace the N with the country code

Most of the larger countries have single letter country codes (eg, UK - G, France - F, Germany - D, China - B ), followed by four letters. That gives 456976 combinations per (single letter coded) country.
The countries that have two letter codes (eg, Australia - VH, Ireland - EI) followed by three letters, which gives 17576 combinations per two letter coded country.

Bring in the countries like the US and Japan which have combinations of letters and numbers and the number of combinations gets even bigger. The US is N and one to five numbers, one to four numbers followed by one letter or one to three numbers followed by two letters, allowing just over a million combinations (assuming my maths is correct). And that is just for the US N-register.
Japan is JA- followed by either four numbers, three numbers followed by a letter or two numbers followed by two letters, giving about 100,000 combinations.


If we assume that new aircraft can take the registrations of scrapped aircraft (and even if we don't assume that), then I really don't think there'll be a problem with running out.

However, the game itself can't be relied upon when it comes to this. There may be thousands of combinations but, we are likely to get these scenarios:

Someone intends to have 10 737s. He orders 5 first and reserves 9M-MKA-MKE, but intends to have up to 9M-MKJ. His competitor can quickly take MKF and so on just to mess things up.

I also have a feeling many won't get their desired registrations and will complain about unfairness etc

I think that the series should be done at random. however, if you order several aircraft at once, then it makes a series. This seems to happen in reality, IE with BA's 777s, one batch has one set of registrations, wheras the other batch had a completely different set of registrations.

saying that there is 25 letters in the alphabet you would have a maximum of 2.5 * 999999 combinations so...
2,499,997 aircraft would be the max a world can take.

Isn't there 26?
Secondly, I beg to differ. My calculations say that each individual country could handle up to half a million, if the system adopted the real world mentality.

I don't think there should be any means of reserving any codes, just get what your given, aside from batches. Perhaps a preference could be requested, but there should be no reservations.

[bolli]

no.....
the equation would be 24!/(24-*number of letters in reg)!

ie for the UK with 4 changable letters in reg it is
24!/20!=255024

Ok, we all know how it will approximately work and what the format will be. However, I still have some questions :
- What happens when an aircraft is leased from the system ? Do the aircraft retain their initial registration ? VP-*, TF-*, EI-* registrations, like some of the major leasing companies around ?
- Will registrations be reusable ? For example, I have a 15-year old 727 and am replacing it with a more modern aircraft. When will I be able to reuse the registration of the 727 ? (10 year-period of inactivity, like in some countries ?)
