Hi i am new to this sight so appologies in advance if there is an easy solution to this but does any body have a problem in listing A40 registrations. Everytime i try to log one it tells me it doesnt exist?
Are you keying in the correct character? The registration prefix is A4O (as in capital letter 'O'), rather than A4zero. This should enable you to log Omani registrations.
Thanks for your help cured it. Are Omani Registrations a Capital Letter 'O' as in other databases i use they are a numeric 40?
Hey Andy, Welcome to the site!
I've just been looking into this, and every website listing country code prefixes has Oman listed as A4zero, whereas every fleet listing site I have tried has them listed as A4Oh.
In the database here we use A4Oh, so I suggest using that for now. Can someone shed any more light on this - which one is correct?
I understand that it is A4Oh, capital O.
As you can see the correct ICAO prefix since 1974 for Oman is A4zero not A4 letter O.
A2- VQ-ZE, -ZH Botswana 1972-
A3- Tonga
A40- Oman 1974-
A5- Bhutan
A6- United Arab Emirates 1977-
A7- Qatar 1975-
A9C- Bahrain 1977-
AP- Pakistan 1947-
B- XT- China 1975-
B- Taiwan 1949-
Obviously people over the years have thought the zero is a letter.

Jinx thanks - I hadn't seen that site or that listing.
Is it possible though that the prefix start as A4 then a letter O was added in the same way that a letter C has been added to A9 for Bahrain?
I've just had a look at the Oman Civil Aviation Website, there is a document about aircraft registration which states:
47.53 Display of marks; general (a) The nationality mark of the aircraft shall be the capital letter ‘A’ in Roman character followed by Arabic number ‘4’ and Roman character ‘O’. The Registration mark shall be a group of two capital letters in Roman character assigned by the Authority on the registration of the aircraft. The letters shall be without ornamentation and a hyphen shall be placed between the nationality mark and the registration mark.

So it definitely is "A4O-.." with a letter O
I stand corrected, no doubt about it with that document as evidence it is O. I live an learn as i always thought it was a zero.
On investigation i have discovered there is no Roman numeral for zero, but the Roman letter O used in middle eastern place names looks like a zero '0', hence the possible confusion.
Me too, I'd thought it was zero until quite recently.
Cheers

Thanks for clarifying that Dougie. Good to finally have a firm answer on this one :)
