Upper Winds Questions

Airfield elevation 5500ft, QNH 1023, temperature 22°C. What is the density altitude?

The barometric pressure at the aerodrome level, computed to mean sea level using the ISA formula. With this set, the altimeter would indicate the height of the aircraft above sea level.

The instrument used to measure wind speed is

Fog is when the visibility is less than

CAVOK means

There are 3 stages of a thunderstorm.

Haze is used to describe conditions when visibility is less than

Katabatic winds

This type of wind begins its formation at the interior plateau and makes it way to the coastline where the wind is Hot and dry.

With the barometric pressure set at the aerodrome level, the altimeter will indicate 0 ft on the ground, this would be:

During the adiabatic process the following changes:

The average lapse rate in temperature is:

The process of heat transfer by horizontal motion that creates wind is known as:
