2 Engine failure emergencies on heavy jets

[Exaviator]

Hi Shanx,

On the Boeing 747 pilots are trained and regularly practice both single engine failure, usually occurring at or close to V1 during T/Off followed by the loss of a second engine during the detail. They have to be able to demonstrate proficiency in carrying out an ILS approach to minima usually followed by a go around with one engine inop. The second engine is then failed leading to a two engine inop approach and landing. On the B747 once the landing gear is extended one is committed to landing - so you have to get it right the first time. As a result of the two incidents of flight into volcanic ash (BA & SIA) pilots also practice dealing with a total, all engines failure with partial engine re-start.
