3.6.8.8 Dangers of flying in poor visibility

Flying visibility refers to the visibility from an aircraft and ahead.

The danger of flying in poor visibility is:

- Firstly, that you may fly into something you cannot see.

- Secondly, that you no longer have a horizon to navigate by and risk spatial

disorientation.

Also, remember that in poor visibility, there is a tendency to overestimate

distances.

Objects are closer than you think!

Be aware of reduced visibility when:

- Temperature and dew point temperature are the same, or nearly

the same.

- Snow, drizzle or rain is reported.

- Fog, Mist or Haze is present.
- During inversions.

- During dust and sand blowing.
