Diversion Airport
Diversion airports are airports capable of handling a particular ETOPS The Extended-range Twin-engine Operations Performance Standards (ETOPS) () are safety standards set by the International Civil Aviation Organization (ICAO) for Twinjet, twin-engine commercial passenger aircraft operations. They are a safety measu ...-rated aircraft during an emergency landing and whose flying distance at the point of emergency does not exceed the ETOPS diversion period for that aircraft. Any airport designated as an en route diversion airport must have the facilities to safely support that particular aircraft, and weather conditions at the time of arrival must allow a safe landing with an engine or systems malfunctioning. An ETOPS/LROPS flight may be conducted solely if the diversion airports are available throughout the length of the flight. Unavailability due to bad weather, for example, might require an inflight rerouting. In the United Kingdom, "Plan 39" is a system of pre-approved slots ...

ETOPS
The Extended-range Twin-engine Operations Performance Standards (ETOPS) () are safety standards set by the International Civil Aviation Organization (ICAO) for Twinjet, twin-engine commercial passenger aircraft operations. They are a safety measure intended to ensure that in the event of a single engine failure, an aircraft will still be able to reach a diversion airport using the remaining operational engine. This may be at a reduced speed and/or height, and usually applies to flights over water or remote lands, typically routes previously restricted to three- and four-engine aircraft. History In 1936, the predecessor to the Federal Aviation Administration (FAA), the U.S. Bureau of Air Commerce, restricted commercial operations within United States airspace to within of an adequate airport. For many aircraft of that era this meant about 60 minutes with one engine inoperative. In 1953, with Aircraft engine#Reciprocating (piston) engines, piston engine reliability and aircraft ...

Airport Slot
__NOTOC__ A landing slot, takeoff slot, or airport slot is a permission granted by a slot coordinator to use the infrastructure of an airport designated as Level 3 (Coordinated Airport) for take-off and/or landing at a specific time and date. Slots should be administered by an independent slot coordinator, often a government aviation regulator such as the U.S. Federal Aviation Administration. In some countries, airport operators are appointed as coordinators even though they are interested parties. Slots are allocated in accordance with guidelines set down by the Worldwide Airport Slot Board with 7 members each from International Air Transport Association (IATA), Airport Council International (ACI) and the Worldwide Airport Coordinator Group (WWACG). All airports worldwide are categorized as either Level 1 (Non-Coordinated Airport), Level 2 (Schedules Facilitated Airport), or Level 3 (Coordinated Airport). At Level 2 airports, the principles governing slot allocation are less str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
