What is airship superheat?
A) A condition of excessive exterior temperature of the envelope.
B) The temperature of the lifting gas exceeding the red line.
C) The difference between outside air temperature and the temperature inside the envelope.
Which action is necessary in order to perform a normal descent in an airship?
A) Valve gas.
B) Valve air.
C) Take air into the aft ballonets.
During flight in an airship, when is vertical equilibrium established?
A) When buoyancy is greater than airship weight.
B) When buoyancy equals airship weight.
C) When buoyancy is less than airship weight.
To check the gas pressures (pressure height) of an airship during a climb, the air damper valves
A) opened forward and closed aft.
B) opened aft and closed forward.
In relation to the operation of an airship, what is the definition of aerostatics?
A) The gravitational factors involving equilibrium of a body freely suspended in the atmosphere.
B) The science of the dynamics involved in the expansion and contraction of hydrogen gas.
C) The expansion and contraction of the lifting gas helium.
How does the pilot know when pressure height has been reached?
A) Liquid in the gas manometer will rise and the liquid in the air manometer will fall below normal
B) Liquid in the gas and air manometers will fall below the normal level.
C) Liquid in the gas manometer will fall and the liquid in the air manometer will rise above normal
When the airship is at pressure height and superheat increases, constant pressure must be
maintained by valving
A) gas from the envelope.
B) air from the envelope.
C) gas from the ballonets.
Air damper valves should normally be kept closed during climbs because any air forced into the
A) increase the amount of gas that must be exhausted to prevent the airship from ascending at an
excessively high rate.
B) increase the amount of air to be exhausted, resulting in a lower rate of ascent.
C) decrease the purity of the gas within the envelope.
To land an airship that is 250 pounds heavy when the wind is calm, the best landing can usually be
made if the airship is
A) in trim.
B) nose heavy approximately 20°.
C) tail heavy approximately 20°.
(Refer to figure 25.) An airship passes over the Quitman VOR-DME area 2) at 0940 and then over
the intersection of the powerline and Victor 114 at 0948. Approximately what time should the flight
arrive over the Bonham VORTAC (area 3)?
