Continually veer
7. Where are easterly and westerly jets found?
Southern hemisphere only
Northern hemisphere only
There are no easterly jets.
Northern and southern hemisphere
8. What is the relationship between the 2000 ft wind and the surface wind in the Northern Hemisphere
surface winds blow across isobars towards a low
surface winds have laminar flow
surface winds blow across isobars towards a high
surface winds blow parallel to isobars
9. What causes the Geostrophic wind to be stronger than the gradient wind around a low?
Coriolis force opposes the centrifugal force
Coriolis force adds to the gradient force
Centrifugal force adds to the gradient force
Centrifugal force opposes the gradient force
10. Wind at altitude is usually given as …….. in ……..
True, m/s
Magnetic, KT
Magnetic, m/s
True, KT
11. For the same pressure gradient at 50°N, 60°N and 40°N, the geostrophic wind speed is?
Least at 50N
Greatest at 60N
The same at all latitudes
Greatest at 40N
12. What is the relationship between the 5000 ft wind and the surface wind in the southern hemisphere
surface winds are veered from the 5000ft and have the same speed
surface winds are backed from the 5000ft and have a slower speed
surface winds are veered from the 5000ft and have a slower speed
surface winds are backed from the 5000ft and have a faster speed
13. In central Europe, where are the greatest wind speeds?
5500m
Where the air converges
Tropopause level
Above the Alps
14. At a coastal airfield, with the runway parallel to the coastline. You are downwind over the sea with the runway to your right. On a warm summer afternoon, what would you expect the wind to be on finals?
Crosswind from the left
Tailwind
Headwind
Crosswind from the right
15. The wind in the Northern Hemisphere at the surface and above the friction layer at 2000 ft would be?
Veered at the surface, backed above the friction layer
Veered at the surface, veered above the friction layer
Backed at the surface, backed above the friction layer
Backed at the surface, veered above the friction layer
16. Flying from an area of low pressure in the Southern Hemisphere at low altitudes, where is the wind coming from?
Left and slightly on the tail
Left and slightly on the nose
Right and slightly on the nose
Right and slightly on the tail
17. Where would an anemometer be placed?
next to the runway, 1m above ground
on the roof of the station
close to station, 2m above ground
10m above aerodrome elevation on a mast
18. What is the difference between Gradient and Geostrophic winds?
A lot of friction
Different latitudes and densities
Curved isobars and straight isobars
Difference in temperatures
19. What is a land breeze
From land over sea by day
From sea over land by day
From sea over land by night
From land over water at night
20. The Geostrophic Wind blows at your flight level in Northern Hemisphere the true altitude and indicated altitude remain constant, is the crosswind
From the left
No crosswind
From the right
Impossible to determine
21. When heading South in the Southern Hemisphere you experience Starboard drift
You are flying away from a lower temperature
You are flying out of a high
You are flying towards a lower temperature
You are flying towards a low pressure
22. Which of the following is an example of a Foehn wind?
Chinook
Ghibli
Bora
Harmattan
23. What causes wind?
Difference in pressure
Rotation of the earth
Difference in temperature
Frontal systems
24. What is the Bora?
An anabatic wind in the Rockies
Northerly wind blowing from the Mediterranean
Warm anabatic wind blowing to the Mediterranean
Cold katabatic wind over the Adriatic
25. What is the effect of a mountain valley wind?
it blows from a valley up a mountain by day
it blows down a mountain to a valley at night
it blows from a valley up a mountain at night
it blows down a mountain to a valley during the day
26. The gradient wind is more than geostrophic wind around an anticyclone because the
effect of coriolis is added to friction
centrifugal force is added to the pressure gradient
centrifugal force opposes the pressure gradient
coriolis effect opposes the centrifugal force
27. A large pressure gradient is shown by
Close spaced isobars - strong winds
Closely spaced isobars - low temperature
Distant spaced isobars - high temperature
Close spaced isobars - light winds
28. ATC will only report wind as gusting if
Gusts to over 25kts
Gusts exceeds mean speed by 10kts
Gust speeds exceeds mean speed by >15kts
Gusts to over 25kts
29. 90km/hr wind in kts is
30
50
60
70
30. Comparing the surface wind to the 3000ft wind
Surface wind veers and is less then the 3000ft wind
Surface wind blows across the isobars and is less than the 3000ft wind
Both are the same
Surface wind blows along the isobars and is less than the 3000ft wind
31. An aircraft is flying East to West in the Northern Hemisphere. What is happening to his altitude?
If the wind is from the south, he will gain altitude
If the wind is from the north, he will gain altitude
Flying into a headwind will decrease altitude
Tailwind will increase altitude.
