Final answer:
Extended crossbleeding of a failed engine traps feed tank fuel on that side if the light has not been pushed, and may result in a fire.
Step-by-step explanation:
Extended crossbleeding of a failed engine traps feed tank fuel on that side if the light has not been pushed, and may result in a fire.
In an aircraft, crossbleeding refers to the process of transferring fuel from one side of the aircraft to the other. If a failed engine's crossbleeding system is extended, it can cause the fuel in the feed tank on that side to be trapped. This can be dangerous if the light indicating the issue has not been pushed, as it may result in a fire.
