In the Northern Hemisphere, where would a pilot likely find favorable winds when flying from East to West?

When flying from East to West in the Northern Hemisphere, a pilot is likely to find favorable winds South of a high-pressure system and North of a low-pressure system due to the typical wind patterns associated with these systems.

In the Northern Hemisphere, high-pressure systems usually lead to winds rotating in a clockwise direction, whereas low-pressure systems have winds that rotate counterclockwise. As a result, flying south of a high-pressure area allows the pilot to harness the prevailing westerlies, which are the dominant winds at mid-latitudes. These winds generally flow from west to east, creating a favorable condition for a flight heading in the opposite direction, as they can offer a tailwind.

Hence, the most advantageous route for a pilot traveling from East to West would be to navigate to a position that takes advantage of the winds flowing in from the south, maximizing efficiency and reducing flight time.
