Question 4

The density of helium gas under standard conditions is:

Accepted Answer

0,2 kg / m3

Answer

2 kg / m3

Answer

0,02 g / m3

Answer

0,2 g / m3

Question 5

Which of the following options states the working principle of a vertical speed indicator?

Accepted Answer

Measuring the present static air pressure and comparing it to the static air pressure inside a reservoir

Answer

Static air pressure is measured and compared against a vacuum

Answer

Measuring the vertical acceleration through the displacement of a gimbal-mounted mass

Answer

Total air pressure is measured and compared to static pressure

Question 6

What is the purpose of the closing rope of a gas balloon?

Accepted Answer

To close the appendix

Answer

To close the sand disposer

Answer

To close the emergency opening

Answer

To secure the towing rope

Question 7

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 8

The towing rope of a gas balloon can be found on ...

Accepted Answer

The rip panel side

Answer

The sandpourer side

Answer

The sliding side

Answer

The entry side

Question 9

QFE is the...

Accepted Answer

Barometric pressure at a reference datum, typically the runway threshold of an airfield

Answer

Altitude above the reference pressure level 1013.25 hPa

Answer

Magnetic bearing to a station

Answer

Barometric pressure adjusted to sea level, using the international standard atmosphere (ISA)

Question 10

What technical measure provides electric conductivity to the hull ropes of a web-less gas balloon?

Accepted Answer

Embedded steel threads (filaments)

Answer

Wrapping with plastic tape

Answer

A surface painting

Answer

Impregnation of the ropes
