Buenas!

No se si lo habréis visto, o tan siquiera os habréis enterado, pues yo no le he hecho hasta hoy, y como no he visto que nadie haya hecho mención a lo siguiente, aquí os lo dejo.

Se trata de un vídeo grabado por un pasajero de un A320 de Avianca con el "motor ardiendo" (no se muy bien como expresarlo...).

Cuando menos tiene que imponer el verse en esa situación...

La lista de los aviones comerciales con esa capacidad (técnicamente se conoce como "fuel jettison") incluye:

Boeing 747, Boeing 767, Boeing 777, Boeing 787, McDonnell Douglas MD-11, Airbus A330 (no todos), Airbus A340, Airbus A350 y Airbus A380, salvo error u omisión.

BOEING 767 BRIEFINGS GENERAL

• The captain is legally allowed to make an overweight landing at destination, when the take-off weight of the aircraft was so calculated that the estimated landing weight at destination would not exceed the allowable maximum landing weight as specified in the AOM.

• When landing at an aerodrome not being the flight plan destination, the actual landing weight could be considerably higher than the maximum landing weight. In this case, fuel dumping must be considered. In view of the many factors that have to be taken into
account, a uniform recommendation cannot easily be given.

• Although overweight landings do not necessarily have to cause structural damage if a minimum rate of descent is achieved on landing, it is recommended to dump fuel when the normal dumping procedure can be followed correctly and all circumstances are
favorable.

FACTORS WHICH INFLUENCE FUEL DUMPING

• Tests to determine safe methods of fuel dumping revealed the following facts :

- When dumping fuel from an aircraft in flight, the combustible gas envelope surrounding the liquid fuel spray, presents practically no hazard to external or internal components of the aircraft;

- Static discharges may, however, ignite sprayed fuel in an air stream;

- Even if ignition might occur, no hazard will have to exist as long as the fuel does not contact any part of the aircraft after leaving the dump chute;

- When an external surface is contacted by ignited fuel, burning of the surface might continue after the source of ignition has disappeared;

- Hazard is increased by the presence of protuberances and irregularities on the surface of the aircraft, by deflection of flaps, control surfaces and gear or an increase of the angle of attack.

• No fuel must be dumped :

- Under weather conditions in which static electricity may be expected (thunderstorms);
- In areas of turbulence;
- In case of external fire
- Below altitudes of approximately 3000 ft*, except in case of engine failure at take-off or initial climb, when immediate dumping may be required to obtain necessary performance. Do not fly into jettisoned fuel (no holding pattern)
