You change 28,92 to 1020 and the altimeter will indicate a higher altitude.

9. Correction by temperature. A plane is flying inside a cold air mass with a determined QNH. Suddenly the temperature starts increasing due to a hot air mass.

The plane will fly at lower height but same indicated altitude. c. The pilot does not have to maintain the altimeter setting. d. The temperature does not aXect to the height or altitude.

10. The Coriolis force is an inertial or fictitious force that acts on objects in motion within a frame of reference that rotates with respect to an inertial frame. The Coriolis force determine the sense of rotation of anticyclones and low pressure areas. Identify the next picture: a. Low pressure area in the south hemisphere. b. Anticyclone in the north hemisphere. c. Low pressure area in the north hemisphere. d. Anticyclone in the south hemisphere.

Anabatic wind is formed during day and climbs the hillside. c. Katabatic wind is formed during day and falls along the hillside. d. Anabatic wind is formed during night and falls along the hillside.

13. The dew point ("qsat") is the exact point where the water vapor contained inside a certain air mass cannot be longer contained as a vapor and starts transforming into liquid. How can be this situation reached?. a. Augmenting the humidity in the air mass. b. Heating the air mass. c. Mixing two air masses far to the dew point. d. All of the above.
