Complete the following statement regarding magnetic variation. The charted values of magnetic variation on earth normally change annually due to:
P) magnetic pole movement causing numerical values at all locations to increase or decrease
N) an increasing field strength causing numerical values at all locations to increase.
N) magnetic pole movement causing numerical values at all locations to increase.
N) a reducing field strength causing numerical values at all locations to decrease.

In flight, a pilot can improve the range of his transmission with a VDF operator by:
P) increasing altitude.
N) flying out of clouds.
N) decreasing altitude.
N) speaking louder.

When is the magnetic compass most effective?
P) About midway between the magnetic poles
N) In the region of the magnetic North Pole.
N) In the region of the magnetic South Pole.
N) On the geographic equator

(Kaut gan formāli šī jautājuma saturs neiziet ārpus PPL prasībām, reāli šāda veida aprēķinu nepieciešamība privātpilotam ir stipri apšaubāma))
Given:
True altitude 9000 FT,
OAT -32°C,
CAS 200 kt.
What is the TAS?
P) 220 kt
N) 200 kt
N) 215 kt
N) 210 kt

Piezīme: jāpievērš uzmanība, ka uzdevuma noteikumos ir dots TRUE ALTITUDE, nevis Pressure Alt. Vispirms ir jākonvertē TA uz PA, izmantojot augstuma logu uz E-6B / CRP-5. Rezultāts – Pressure Altitude = 10 000 ft. Tad sanāk precīzi 220 kt.
Ja uzreiz savieto 9000 ft ar –32C ātruma logā, tad atbilde sanāk ap 216 kt, bet šāda atbilde ir nepareiza.
Neuzskatu, ka šādas kalkulācijas nepeciešamas privātpilotiem, tāpēc iesaku vienkārši atcerēties atbildi, bet neuzķerieties uz nedaudz izmainītiem uzdevuma notiekumiem, kas var tikt izdarīts no CAA puses nākotnē!

(ATPL jautājums)
Seasons are due to the:
P) inclination of the polar axis with the ecliptic plane
N) Earth's elliptical orbit around the Sun
N) variable distance between Earth and Sun
N) Earth's rotation on its polar axis

(Subject – Aircraft General Knowledge, Instruments)
When an aircraft on a westerly heading on the northern hemisphere accelerates, the effect of the acceleration error causes the magnetic compass to:
P) indicate a turn towards the north.
N) to turn faster than the actual turning rate of the aircraft.
N) lag behind the turning rate of the aircraft.
N) indicate a turn towards the south.

(ATPL jautājums)
A direct reading compass should be swung when:
P) there is a large, and permanent, change in magnetic latitude.
N) there is a large change in magnetic longitude.
N) the aircraft is stored for a long period and is frequently moved.
N) the aircraft has made more than a stated number of landings.

What is the difference in longitude between A and B?
P) 050°
N) 020°
N) 130°
N) 001°
