Figure 17-3. Slant visibility may be severely reduced by fog, smog or stratus.

Figure 17-4. Reduced visibility and smooth flying conditions will usually be encountered beneath an inversion, and possible windshear passing through it.

Figure 17-5. Radiation fog.

Figure 17-6. The wind strength will affect the formation of dew/frost, mist/fog, or stratus.

Figure 17-7. Fog or stratus caused by advection.

Figure 17-11. Friction and obstacles affect the surface wind.

Figure 17-12. Avoid flying near mountains in strong winds.

Figure 17-13. Vertical gusts increase the angle of attack, and will increase the load factor and/or stall the wings.

Figure 17-14. Windshear is a change of wind speed and/or direction between places.
