oxygen or cabin pressurization systems help pilots fly at higher altitudes and overcome the effects of oxygen deprivation. Wind and Currents Air flows from areas of high pressure into areas of low pressure because air always seeks out lower pressure ... earth cause two kinds of atmospheric motion: convective currents (upward and downward motion) and wind (horizontal motion). Currents and winds are important as they affect takeoff, landing, and cruise flight operations. Most importantly, currents and winds or atmospheric circulation cause…

clear obstacles during the approach. Figure 12-13. Sea breeze and land breeze wind circulation patterns. Figure 12-14. Currents generated by varying surface conditions. Figure 12-15. Turbulence caused by manmade obstructions. This same condition is even more noticeable ... when flying in mountainous regions. [Figure 12-16] While the wind flows smoothly up the windward side of the mountain and the upward currents help to carry an aircraft over the peak of the mountain, the wind on the leeward…
