B777 & Runway shoulders
Ops Guy....
B777 is an ICAO 'Code E' type for airfield infrastructure, but so is the A330. According to ICAO Annex 14 and the UK's CAP 168, a Code E runway of 45m width should have 7.5 metres paved shoulders. The A330 has been using this runway for some time, presumably on a safety case type approval from the CAA. FOD due to blast or erosion of the grass shoulder should not be any greater an issue with the B777, being a twin. Ultimately it will be a matter for NCL to agree with the CAA, having looked at any other safety issues which may arise from the absence of paved shoulders.
