Information About

Aircraft Registration




An aircraft registration is a unique Alphanumeric string that identifies a civilian Aircraft . All ICAO countries require aircraft over a certain weight to be registered with a national aviation authority. Upon registration, the aircraft receives its unique "registration" which must be displayed prominently on the aircraft. Since for Airplane s, this is usually the aft fuselage, the registration is often referred to as the '''tail number'''.

The aircraft registration is made up of a prefix selected from the countries Callsign Prefix allocated by the ITU (making the registration a quick way of determining the country of origin) and the registration suffix. Depending on the country of registration, this suffix is a numeric or Alphanumeric code and consists of one to five digits or characters respectively.

When painted on the fuselage, the prefix and suffix are separated by a dash (for example YR-BMA), however when entered in the Flight Plan , the dash is omitted (for example YRBMA). Private aircraft usually use their registration as Callsign , but most commercial aircraft use a company callsign. In some instances, it may be sufficient to simply display the suffix letters, with the country prefix omitted. For example, Gliders registered in Australia would omit the VH prefix and simply display the suffix. Obviously this is only suitable where the aircraft does not fly in the airspace of another country.

Even if the suffix consists of characters in a certain country, gliders and ultralights may sometimes use digits instead. For example, D-ABCD can be an aircraft, while D-1234 is a glider registered in Germany. In Australia, early glider registration suffixes began with the letter "G", and it is not uncommon to find such gliders only displaying the last two letters of the suffix. For example, VH-GIQ would simply be displayed as IQ.
