At low latitudes

Question 12

Magnetic dip can be defined as

Answer 12

The angle between a magnetic needle in a compass and the
horizontal.

Question 13

As latitude increase, the effect on the earth’s magnetic field is that the

Answer 13

Horizontal component decreases, dip angle increases

Answer 17

Mean Sea Level

Question 18

. International Standard Atmosphere defines a change in temperature with
increasing height. This is:

Answer 18

15°C at mean sea level reducing by 1.98°C per 1,000ft up to 36,090ft
where the temperature remains at a constant -57°C.

Atmosphere?

Answer 21

+4 C

Question 22

You are planning a cross-country flight requiring the pressure altitude to
calculate true airspeed (TAS). Your planned altitude is 2,400ft and the
regional QNH is 998 hPa. Wheat is the pressure altitude for planning
purposes (use 1hPa=30ft)?
