Static air pressure is...

• the amount of pressure exerted by a fluid that is not flowing

• only the weight of air pushing upwards

• only the weight of air pushing downwards

• only the weight of air pushing sideways

Dynamic pressure is...

• pressure due to movement of air

• pressure due to movement of electrons independent of an electrical field

• pressure exerted on an object by air when in a perfect vacuum

• pressure that is constantly changing

The pressure measured or collected by a pitot probe consists of..

Pitot heat is used to...

• remove any water from the air entering the pitot tube

• remove any water from the air entering the static vent

• prevent or remove any ice from the pitot head

• remove any ice from the static air pressure system

Looking at the Christchurch ATIS in the picture, what is the density altitude?
