Question 1

The assembly of the panels to the hull of a web-less gas balloon is done ...

Accepted Answer

By glueing.

Answer

By vulcanisation.

Answer

By stitching.

Answer

By welding

Question 2

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

Accepted Answer

An altitude indication which is too high.

Answer

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

Answer

An altitude indication which is too low.

Answer

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

Question 3

How will the sag of the pull rope change during descent?

Accepted Answer

It will decrease

Answer

It will remain unchanged

Answer

It will increase

Answer

It will change periodically

Question 4

The emergency opening of a gas balloon is located where?

Accepted Answer

To the side of the appendix

Answer

At the upper pole

Answer

At the equator

Answer

To the side of the valve

Question 5

The purpose of the drag lines of the parachute is ...

Accepted Answer

To transfer the force from the pull rope to the parachute.

Answer

To transfer the carrying force of the balloon in the top opening area

Answer

To keep the parachute in the center of the top opening.

Answer

To transfer the force from the pull rope to the free-balloon hull.

Question 6

A true altitude is...

Accepted Answer

An altitude above mean sea level corrected for non-standard temperature.

Answer

A height above ground level corrected for non-standard pressure

Answer

A height above ground level corrected for non-standard temperature.

Answer

A pressure altitude corrected for non-standard temperature.

Question 7

During a flight in an air mass with a temperature equal to ISA and the QNH set correctly, the indicated altitude is...

Accepted Answer

Equal to the true altitude

Answer

Higher than the true altitude.

Answer

Lower than the true altitude.

Answer

Equal to the standard atmosphere.

Question 8

During a flight in colder-than-ISA air the indicated altitude is...

Accepted Answer

Higher than the true altitude

Answer

Equal to the standard altitude.

Answer

Lower than the true altitude.

Answer

Eqal to the true altitude.

Question 9

A gas balloon has to be equipped with which tethers?

Accepted Answer

2 at 10 m or 1 at 20 m

Answer

1 at 40 m or 4 at 10 m

Answer

1 at 30 m or 3 at 10 m

Answer

2 at 20 m or 1 at 10 m

Question 10

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
