Answer

Total air pressure is measured and compared to static pressure

Answer

Static air pressure is measured and compared against a vacuum

Answer

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

Question 2

Accepted Answer

Height above airfield

Answer

Pressure altitude

Answer

Altitude above MSL

Answer

Airfield elevation

Question 3

A vertical speed indicator measures the difference between...

Accepted Answer

Instantaneous static pressure and previous static pressure.

Answer

Dynamic pressure and total pressure.

Answer

Total pressure and static pressure.

Answer

Instantaneous total pressure and previous total pressure.

Question 4

What is the purpose of the vapourizor coils of the burner system?

Accepted Answer

To heat the liquid gas, so it will vapourize immediately after exiting the burner nozzle

Answer

To induce a rotation movement in the liquid gas to get a better mixture

Answer

For cooling of the liquid gas after exiting the burner nozzles

Answer

To vapourize the liquid gas, so it will be emitted from the burner nozzle in gasous form

Answer

It has an especially smooth surface.

Answer

It is fixed to the lower basket area

Answer

It has to be lubricated before every take-off

Question 7

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 to heavy otherwise.

Answer

To provide space for expansion in case of external cooling

Question 10

What ist the purpose of the sounding pipe valve?

Accepted Answer

To indicate the volumetric filling limit.

Answer

It allows pressure equalization during cruise at high altitude

Answer

It prevents air from entering the burner system

Answer

For venting the liquid gas container bottle.
