context_page_description: Mustique Airport is a private airfield owned by the Mustique Company for public use and is located on Mustique island, part of Saint Vincent and the Grenadines in the Caribbean Sea. It is used by civil aviation and national airlines using turboprop planes.
  The traffic has a large seasonal variation with many more passengers in the winter.
  The airport has a short takeoff and landing runway with a displaced threshold, thus limiting the aircraft types allowed to land. Single-engine light aircraft such as the Cessna 152, Cessna 172, and twin-engine light aircraft such as the Beechcraft King Air, the larger Beechcraft Super King Air or the well-known de Havilland Canada DHC-6 Twin Otter can easily land there.
  The runway is unlit and the airstrip lacked an instrument landing system, radar and other radio navigation aids –used for landings in poor weather. As such, it could normally only support good weather Visual Flight Rules daylight operations, in weather conditions generally clear enough to allow the pilot to see where the aircraft is going.
context_section_description: It was proposed to realign the existing runway at the northern end of Mustique Island to minimize the effects of elevated terrain features near the flight path. The excavation of soil and rock from high ground in the central quarry area and engineered fill placement at the low lying east and west ends of the runway are required to provide an appropriate runway gradient. The existing topography along the centerline of the proposed runway changes from approximate Elev. 1m ASL adjacent to the sanctuary to Elev. 24m ASL in the quarry area. The topography descends to Elev. 2m ASL adjacent to the Rutland Bay seasonal pond in the northeast.
  The geotechnical reporting includes the subsurface investigation findings and recommendations for (a) sub excavation and/or soil improvement of the weak swampy materials comprising wet, soft clayey silt and organics in the west; (b) excavation of overburden soils and soft rock (volcanic tuff) and blasting and excavation of hard rock (grey andesite) in the middle high ground and quarry; and (c) additional subgrade preparation and engineered fill placement in the east section near the seasonal pond at Rutland Bay. Based on the aircraft loading conditions a design for the new asphalt pavement thicknesses, asphalt overlays for the existing apron and runway, and subsurface drainage requirements were provided.
