Question 2

The vapour pressure of propane gas in a bottle depends in particular on:

Accepted Answer

The temperature

Answer

The rigidity of the bottle

Answer

The size of the bottle

Answer

The gas amount

Question 3

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 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

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

Question 4

Damages to the hot-air balloon hull fabric are most critical in which area?

Accepted Answer

At the top area

Answer

In the lower third

Answer

Question 5

Why should a liquid gas bottle only be filled to 80% of its volume?

Accepted Answer

To provide space for temperature-induced expansion

Answer

Because temperature would get too high

Answer

Because it would get too heavy otherwise

Answer

To provide space for expansion in case of external cooling

Question 6

Lower-than-standard temperature may lead to...

Accepted Answer

An altitude indication which is too high

Answer

An altitude indication which is too low

Answer

A correct altitude indication as long as the altimeter subscale is set to correct for non-standard temperature

Answer

A blockage of the Pitot tube by ice, freezing the altimeter indication to its present value
