Une tour virtuelle à EGLL
Le NATS annonce la mise en service d'une tour virtuelle pour EGLL. Surnommé VCF pour Virtual Contingency Facility, Cc bâtiment qui reprend l'exacte configuration de la tour actuelle sans le fût ni les baies est délocalisée à distance de l'aéroport.
L'objectif est de fournir une solution de repli en cas d'incident majeur rendant la "vraie" tour inopérable. Les procédures validées par la CAA permettent de maintenir 70% de la capacité max, elle sont très proche de celles en vigueur en cas de faible visibilité.

Third RWY at EGLL
Le gouvernement a annoncé la décision de création de la troisième piste d'EGLL. Située au Nord du doublet actuel, elle sera disponible en 2020.
Cette décision suscite évidement le mécontentement des riverains ... www.notrag.org

Un nouvel aéroport "londonien" ?
Ce qui suit peut paraître soit du délire soit relever de la promesse électorale qui n'engagera que ceux qui la croiront, les faits sont néanmoins relatés par le Sunday Times:
"How could Alexander Boris de Pfeffel Johnson make his mark and create a genuinely better life for future generations? One neat solution is to end the misery of Heathrow, both for passengers and for the residents unfortunate enough to live under its flight path. Mr Johnson has a plan to do that and the London mayor and his team are working on the details. The scheme, which draws its inspiration from Hong Kong, would feature a Thames estuary airport, built on an artificial island off Sheppey with four (and potentially six) runways.

Critics may scoff at the idea, regarding Sheppey as about as close to the centre of London as one of Ryanair’s destinations. But Mr Johnson’s team have an answer to that, too. Fast trains would whisk passengers there in 35 minutes. The airport would be integrated with Europe’s high-speed rail network so travellers for continental Europe could hop on a train and head through the Channel tunnel. Heathrow would be turned into Britain’s Silicon Valley, a home for high technology firms.

This newspaper has campaigned for a new airport in the Thames estuary rather
than squeezing more into overcrowded Heathrow. Mr Johnson is to be commended
for thinking big and outside the box. It is increasingly evident that
Heathrow is in the wrong place and will never adequately meet the demands of
future air travel. Only a new airport which can operate for 24 hour."
Un projet à la Kansai donc mais en visiblement dexu ou trois fois plus grand ... avec une localisation qui pourrait bien avoir un impact sur le réseau de route ... Maastricht n'a pas fini d'avoir des soucis avec les départs ... et nous avec les arrivées ?

Vachage du B777 à EGLL ... de la glace dans le fuel
Le bureau d'enquête britannique (AAIB) vient de rendre public un premier rapport sur les causes de l'incident survenu à EGLL en janvier 2008 ... voir le post
"The investigation has shown that the fuel flow to both engines was restricted; most probably due to ice within the fuel feed system. The ice is likely to have formed from water that occurred naturally in the fuel whilst the aircraft operated for a long period, with low fuel flows, in an unusually cold environment; although, G-YMMM was operated within the certified operational envelope at all times."

Un nouveau Terminal à EGLL
La reine Elizabeth a inauguré, le nouveau terminal 5 de
l’aéroport londonien, Heathrow.
Outre l’accueil des passagers,
l’immense bâtiment abrite également des magasins de luxe et restaurants
de standing. L’extension de l’aéroport pour la bagatelle de 5,6 millions d’euros est très controversée mais
également critiquée par les défenseurs de l’environnement qui redoutent
l’accroissement de toutes sortes de nuisances et y voient surtout un pas de plus vers la construction d'une 3ième piste à EGLL.
Heathrow est déjà l’aéroport le plus fréquenté au monde avec 67,3 millions de passagers et mais seulement 471 000 mouvements d’avions par an .... derrière CDG !

La finale 27L à EGLL ...
Pour mieux apprécier l'incident du B777 à EGLL, un survol de la finale 27L montre qu'on s'en tire plutôt pas mal !

Premiers éléments sur l'incident à EGLL
Le rapport initial de l'enquête de l'AAIB (le BEA de l'autre coté de la Manche) est sur leur site : http://www.aaib.gov.uk
| Aircraft Type and Registration: | Boeing 777-236, G-YMMM |
| No & Type of Engines: | 2 Rolls-Royce RB211 Trent 895-17 turbofan engines |
| Year of Manufacture: | 2001 |
| Date & Time: | 17 January 2008 at 1243 hrs |
| Location: | Undershoot RWY 27L, London Heathrow Airport |
| Type of Flight: | Commercial Air Transport (passenger) |
| Persons on Board: | Crew - 16 Passengers - 136 |
| Injuries: | Crew - 4 (minor) Passengers - 1 (serious) Passengers - 8 (minor) |
| Nature of Damage: | Substantial |
| Information Source: | AAIB Field Investigation |
Following an uneventful flight from Beijing, China, the aircraft was established on an ILS approach to Runway 27L at London Heathrow. Initially the approach progressed normally, with the Autopilot and Autothrottle engaged, until the aircraft was at a height of approximately 600 ft and 2 miles from touch down. The aircraft then descended rapidly and struck the ground, some 1,000 ft short of the paved runway surface, just inside the airfield boundary fence. The aircraft stopped on the very beginning of the paved surface of Runway 27L. During the short ground roll the right main landing gear separated from the wing and the left main landing gear was pushed up through the wing root. A significant amount of fuel leaked from the aircraft but there was no fire. An emergency evacuation via the slides was supervised by the cabin crew and all occupants left the aircraft, some receiving minor injuries.
The AAIB was notified of the accident within a few minutes and a team of Inspectors including engineers, pilots and a flight recorder specialist deployed to Heathrow. In accordance with the established international arrangements the National Transportation Safety Board (NTSB) of the USA, representing the State of Design and Manufacture of the aircraft, was informed of the event. The NTSB appointed an Accredited Representative to lead a team from the USA made up of investigators from the NTSB, the FAA and Boeing. A Boeing investigator already in the UK joined the investigation on the evening of the event, the remainder of the team arrived in the UK on Friday 18th January. Rolls-Royce, the engine manufacturer is also supporting the investigation, an investigator having joined the AAIB team.
Activity at the accident scene was coordinated with the Airport Fire and Rescue Service, the Police, the British Airports Authority and British Airways to ensure the recovery of all relevant evidence, to facilitate the removal of the aircraft and the reinstatement of airport operations.
The flight crew were interviewed on the evening of the event by an AAIB Operations Inspector and the Flight Data Recorder (FDR), Cockpit Voice Recorder (CVR) and Quick Access Recorder (QAR) were removed for replay. The CVR and FDR have been successfully downloaded at the AAIB laboratories at Farnborough and both records cover the critical final stages of the flight. The QAR was downloaded with the assistance of British Airways and the equipment manufacturer. All of the downloaded information is now the subject of detailed analysis.
Examination of the aircraft systems and engines is ongoing.
Initial indications from the interviews and Flight Recorder analyses show the flight and approach to have progressed normally until the aircraft was established on late finals for Runway 27L. At approximately 600 ft and 2 miles from touch down, the Autothrottle demanded an increase in thrust from the two engines but the engines did not respond. Following further demands for increased thrust from the Autothrottle, and subsequently the flight crew moving the throttle levers, the engines similarly failed to respond. The aircraft speed reduced and the aircraft descended onto the grass short of the paved runway surface.
The investigation is now focussed on more detailed analysis of the Flight Recorder information, collecting further recorded information from various system modules and examining the range of aircraft systems that could influence engine operation.
