In response to the wind shear problems, in June 2016 the Governor, Lisa Phillips, noted that restricting flight operations to runway 02, that is northbound landings and southbound starts on St Helena's single operating surface, might be a suitable interim solution. While runway 02 does not suffer from a significant wind shear problem, restricting landings to one direction would prevent large aircraft from calling at St Helena. Only permitting landings in one direction would mean that aircraft must to be able to land in tailwind. Consequently, large aircraft, like the 737-800, could not be used because, in a tailwind, they would need a longer runway than St Helena provides. If runway 20 is used, it will have severe wind restrictions.
