401. PLT057
(Refer to figure 58.) What is the maximum altitude for the balloon if the gross weight is 1,000 pounds and standard temperature exists at all altitudes?
A) 4,000 feet.
B) 5,500 feet.
C) 11,000 feet.

402. PLT057
(Refer to figure 57.) The gross weight of the balloon is 1,350 pounds and the outside air temperature (OAT) is +51°F. The maximum height would be
A) 5,000 feet.
B) 8,000 feet.
C) 10,000 feet.

403. PLT177
All fuel tanks should be fired during preflight to determine
A) the burner pressure and condition of the valves.
B) that the pilot light functions properly on each tank.
C) if there are any leaks in the tank.

404. PLT250
Why should special precautions be taken when filling the propane bottles?
A) Propane is transferred from the storage tanks to the propane bottles under high pressure.
B) During transfer, propane reaches a high temperature and can cause severe burns.
C) Propane vapor is super-cold and may cause severe freeze burns.

405. PLT254
Why should propane tanks not be refueled in a closed trailer or truck?
A) Propane vapor is one and one-half times heavier than air and will linger in the floor of the truck or trailer.

C) has a lower boiling point.

409. PLT251
If ample propane is available, within which temperature range will propane vaporize sufficiently to provide enough pressure for burner operation during flight?
A) 0 to 30 °F.
B) 10 to 30 °F.
C) 30 to 90 °F.

410. PLT254
