An aircraft on the Isle of Man Aircraft Register recently became one of very few aircraft to have made a stopover at St Helena Airport.

St Helena is a British Overseas Territory in the South Atlantic Ocean. The island’s airport opened earlier this year but commercial flights are yet to commence and due to challenging wind shear conditions and unusual runway characteristics, the airport is Cat C and requires the approval of the aircraft’s State of Registry.

The operator, airport and the Isle of Man Aircraft Registry worked in collaboration to undertake a detailed review of the local procedures and restrictions and assess the results of recent St Helena flight trials. This resulted in the operator being able to develop robust operational procedures and limitations to be applied in accordance with and in the context of their Safety Management System​.

From the start of national aircraft registrations and until 1929 the nationality prefix 'M' was chosen by Spain. From 1929 the Spanish civil aircraft nationality prefix became 'EC' and 'M' was unused.

Following the Chicago Convention and establishment of ICAO in 1947, ICAO Annex 7 set the display standard and the international prefixes were allocated by the International Telecommunication Union (ITU).

‘M’ was allocated, with a number of others, to the UK, due to its large number of overseas territories.

‘M’ was offered to the IOMAR by the UK prior to its establishment in 2007.

The first aircraft on the register was M-ELON, a Cessna 525B.
