Question 11

A forecast of 32015 kt means

Answer 11

Wind strength of 15 knots from a direction of 320°T

Question 12

A sea breeze occurs

Answer 12

In the afternoon when the sun warms the land, the air above it rises and cool air from the sea moves in causing an onshore breeze and lower temps

Question 13

What type of wind is the sea breeze an example of

Answer 13

Anabatic winds

Question 14

What are katabatic winds

Answer 14

Katabatic winds flow down mountains and out of valleys at night and early mornings

Question 15

How are katabatic winds formed

Answer 15

They are formed from cooling of the earth surface at night and the cooling of the air in contact with it, cold air is heavier and sinks, flowing down the mountains

Question 16

Air heated by the earth’s surface rises and causes

Answer 16

Thermals

Question 17

What happens when air is cooled below its dew point

Answer 17

Condensation occurs and clouds form

Question 18

Hot air rising through cooler air will

Answer 18

Cool, if it has enough vapour it will reach its dew point and cloud will form

Question 19

Can 2 children occupy one seat?

Answer 19

CASR 91 MOS 20.03

Question 20

What is the minimum flight height over populated areas and or public gatherings?

Answer 20

You must not fly below 1000ft over the highest feature or obsticle within a 600 meter radius
CASR 91.265 MOS 12.01

Question 21

Ground effect is said to occur roughly from the ground up to how many wing spans?

Answer 21

1 wingspan

Question 22

how does ground effect occur?

Answer 22

Ground effect occurs when the wings cannot produce vortices due to the viscosity of the air near the ground and thus less drag is produced by the wing

Question 23

The use of one stage of flap for take off in most light aircraft, will have what effect on the climb

Answer 23

Change the angle of climb,
