Airplane fuel dumping: How it works
Emergency manoeuvre used to lighten load
Last Updated: May 29, 2012
The fuel dump is used in cases of emergency, when pilots carrying a full load of jet fuel must make an unexpected early landing. A gushing stream of jet fuel is released from the plane and largely evaporates as it descends into the atmosphere. In Canada, there have been 577 incidents involving fuel dumping since 1993, according to Transport Canada.
