Question 5

In a given height, a given amount of ballast is unloaded from a gas balloon. How is the increase in height at 5500 m different from the increase in height at MSL by unloading the same amount of ballast?

Accepted Answer

At 5500 m the increase in height is twice as high

Answer

At 5500 m the increase in height is three times as high

Answer

At both heights the same increase in height is observed

Answer

At 5500 m the increase in height is four times as high

Question 6

In which way may an altimeter subscale which is set to an incorrect QNH lead to an incorrect altimeter reading?

Accepted Answer

If the subscale is set to a higher than actual pressure, the indication is too high. This may lead to much closer proximity to the ground than intended

Answer

If the subscale is set to a higher than actual pressure, the indication is too low. This may lead to much greater heights above the ground than intended

Answer

If the subscale is set to a lower than actual pressure, the indication is too high. This may lead to much closer proximity to the ground than intended

Answer

If the subscale is set to a lower than actual pressure, the indication is too low. This may lead to much closer proximity to the ground than intended

Question 7

Question 9

Which approximate, geometrical form describes the shape of the Earth best for navigation systems?

Accepted Answer

Ellipsoid

Answer

Sphere of ecliptical shape

Answer

Flat plate

Answer

Perfect sphere

Question 10

The aerostatic lift corresponds to which force?

Accepted Answer

The weight of the displaced air

Answer

The dynamic force due to airstream across the top of the hull

Answer

The drag due to airstream around the balloon envelope

Answer

The weight of the balloon less ballast
