What volcano nearly brought down a 747?

What volcano nearly brought down a 747?

On 24 June 1982, the route was flown by the City of Edinburgh, a Boeing 747-200 registered as G-BDXH. The aircraft flew into a cloud of volcanic ash thrown up by the eruption of Mount Galunggung around 110 miles (180 km) south-east of Jakarta, Indonesia, resulting in the failure of all four engines.

What is the recommended procedure when an aircraft has entered an ash cloud?

Aircraft procedures If we detect that we have entered a volcanic ash cloud, our number one priority is to exit it as soon as possible. As we have no idea how far the plume extends either in front of us or to the side of us, the quickest way to do this is by making a 180-degree turn.

What is the main hazard that volcanic ash creates for airplanes?

Volcanic ash ejected into the atmosphere by explosive eruptions has known damaging effects on aircraft. Ash particles can abrade forward-facing surfaces, including windscreens, fuselage surfaces, and compressor fan blades. Ash contamination also can lead to failure of critical navigational and operational instruments.

What happens when a plane flies through volcanic ash?

When volcanic ash, which is usually already very hot, enters a jet engine, it heats can melt and stick together as clumps of molten material. This can quickly cool, solidify and destroy an engine, rendering it completely inoperational, and leaving the aircraft without power.

What volcano redirected the Mayan empire?

It was A.D. 540, and El Chichón—a small and previously unremarkable volcano—had plunged Maya civilization into darkness and chaos.

Can planes fly through volcanic ash?

Should airplanes attempt to fly through ash clouds?

Ash clouds are hard to spot visually and the particles are too small to be detected by radar so in order to minimise risks, airlines have to cancel flights that might in fact be fine to fly.

Is the plane in Casino Royale real?

After retirement, it was modified to be used as a prop in the James Bond movie Casino Royale and was painted with a fictional Hollywood registration, N88892, used also on a Boeing 727 in the movie Hero. In the movie, it appears as the “Skyfleet S570” a fictional prototype aeroplane which terrorists attempt to destroy.

What happens if a plane flies through volcanic ash?

What signs may indicate that an aircraft is flying through volcanic ash?

When encountering volcanic ash, flight crews usually notice a smoky or acrid odour that can smell like electrical smoke, burnt dust or sulphur. Haze. Most flight crews, as well as cabin crew or passengers, see a haze develop within the aircraft cockpit and/or cabin. Dust can settle on surfaces.

Why can’t planes fly through ash clouds?

The biggest danger of flying through an ash cloud is the impact on the engines. An erupting volcano spews ash and particles into the sky, predominantly made up of silicates. This disrupts the airflow which can lead to the engine stalling or failing completely.
