1% of gross lift

Question 25

When the airship is at pressure height and superheat increases, constant pressure must be maintained by valving

Answer 25

gas from the envelope

Question 26

How does the pilot know when pressure height has been reached?

Answer 26

The liquid in the gas manometer will rise and the liquid in the air manometer will fall below normal levels

Question 27

The pressure height of an airship is the altitude at which

Answer 27

the ballonet(s) would be empty

Question 28

The maximum altitude that a rigid airship can reach (under a given atmospheric condition) and then return safely to the surface is determined by

Answer 28

pressure altitude

Question 29

An unbalanced condition of an airship in flight must be overcome by

Answer 29

a negative or a positive dynamic force

Question 30

Air damper valves should normally be kept closed during climbs because any air forced into the system would

Answer 30

increase the amount of air to be exhausted, resulting in a lower rate of ascent

Question 31

To check the gas pressures (pressure height) of an airship during a climb, the air damper valves should be

Answer 31

closed.

Question 32

What condition does a rising barometer indicate for balloon operations?

Answer 32

Decreasing clouds and wind.

Question 33

Why should propane tanks not be refueled in a closed trailer or truck?

Answer 33

Propane vapor is one and one-half times heavier than air and will linger in the floor of the truck or trailer.

Question 34

Why should special precautions be taken when filling the propane bottles?
