de ha fúj a szél mint az állat akkor nem ugyan ott fogsz leesni bruh
mondjuk az egy más kérdés, hogy 10k km magasan sztem semmilyen szél nem fúj
What is a jet stream?Jet streams are strong westerly winds that blow in a narrow band in the Earth’s upper atmosphere – at the altitudes used by most aircraft. Where these packets of fast moving air form a tube, they are called jet streams.
By flying in a jet stream, aircraft travelling from west to east get carried along by the tailwind, saving them time – and/or fuel. In fact most airline pilots are trained to reduce airspeed when the winds are so much to their advantage, to save fuel costs – not to fly in the shortest possible time. Private jet pilots nearly always fly as fast as possible but would of course speak to the customers on-board to ensure that an early arrival time is acceptable.
The North Atlantic jet stream typically reaches its peak intensity during January and February, when the temperature contrast between the equator and the North Pole is largest.
The intensity of the jet stream also has a big impact on the weather – generating polar vortex-related winter conditions.
Airspeed and ground speed are not the same thing though. An aircraft can be flying within normal design limits, well below the speed of sound at altitude, but according to its ground speed, appear to be flying at near-supersonic speeds.
