Why pilots should understanding of high- and low-pressure wind patterns?
There are various reasons!
- It is taking about how to take advantage of beneficial tailwinds.
- It is also related to the direction of wind drift when flying from high to low and vice versa.
- weather is associate with wind pressure system.
In Northern Hemisphere, when planning a flight from west to east, favorable winds would be encountered along the northern side of a high-pressure system AND/OR the southern side of a low-pressure system.
Same concept, in Northern Hemisphere, when planning a flight from east to west, favorable winds would be encountered along the southern side of a high-pressure system AND/OR the northern side of a low-pressure system.
In Northern Hemisphere, if you stand with your back to the wind, the low pressure will be on your left
– Buys Ballout’s law
Apply the above concept, when an aircraft flying from High-pressure to Low-pressure System in Northern Hemisphere, due to the Coriolis Force, right drift will be expected – wind blows from left to right.

In northern hemisphere, “take advantage of beneficial tailwinds” is making full use of the tailwind of a high-pressure system!
