How Does The Jet Stream Work?
Hi Captain,

Last week Flight Radar showed a British Airways Boeing 777-333 from Houston-London doing 731 mph over Ireland,

1. Is that possible?

2. Are there speed restrictions over land and is it different than flying over the Atlantic?

3. Where does the jet stream roughly ends, east - west USA - Europe?.

Thanks

Mike

Hi Mike,

1. Yes, it is possible. You can read a similar question and answer here.

2. Generally there is no speed restriction over land during the cruise. The planes would fly at whatever speed that is specified in their fight plans. The pilot merely inform the air traffic control if they are flying faster than their planned speed. However if the plane is flying over the OTS (Organized Track System) routes over the Atlantic, then they have to fly at a same constant speed as specified by the air traffic controllers and spaced at 10 minutes interval so that they do not catch up with each other.

3. The jet streams are always flowing towards the east in the Northern Hemisphere due to the earth’s rotation. Hence planes always fly faster from Houston to London and slower on the return journey.

Where a strong jet stream begins and ends would vary with the seasons. The flow will be further up north in summer than in winter. (See the YouTube videos for detailed explanation).


What is the jet stream and how does it work?
