Question

airaplanes sometimes at the same altitude at which jet streams blow how would a jet stream affect a plane flying from New York to Los Angeles? Explain.

Answer 1

The jet streams are narrow bands of fast moving air.  They travel from the west coast towards the east coast over the United States, and so an aircraft flying from New York to Los Angeles would be flying into the jet stream rather than with it.  This would cause the following:
- The flight would use more fuel, as the aircraft must push its way against the force of the jet stream 
- The flight would also take longer, as thrust is needed to push against the jet stream as well as to push the aircraft forwards.
