Suppose you are a commercial airline pilot planning for a round-trip flight between Los Angeles, California (on the US west) and New York City (on the US east coast) in the month of January at a planned cruising altitude of about 30,000 feet.
In the flight planning process, you check the Aviation Weather Center website’s wind and temperatures plot (Links to an external site.) and pull up a map for the forecast winds for the planned flight level, valid for the time frame of the round-trip flight.
Explain how the map information will be used for estimating the flight duration time and fuel requirements for each leg of the flight.
Identify (by name) the specific wind feature that would also be identified using the map information, and explain why determining the strength and position of this feature should be considered in determining the actual flight route and flight level for each leg of the flight.
