Answers (Verified Answers) Plus Rationales
2026 Q&A | Instant Download Pdf
1. What gas is most commonly used to fill hot-air balloons for lift?
A. Helium
B. Heated air
C. Hydrogen
D. Nitrogen
Rationale: Hot-air balloons rely on heated air for lift, as it becomes less
dense than the surrounding cooler air.
2. What is the primary lifting force in a gas balloon?
A. Heated air expansion
B. Buoyancy from lighter-than-air gas
C. Propeller thrust
,D. Air pressure differentials
Rationale: Gas balloons use gases such as helium or hydrogen, which are less
dense than air, to create buoyancy.
3. What type of envelope fabric is most commonly used in modern hot-air
balloons?
A. Cotton
B. Polyester
C. Ripstop nylon
D. Silk
Rationale: Ripstop nylon is strong, lightweight, and heat-resistant, making it
ideal for balloon envelopes.
4. The FAA requires maintenance of a Light-Sport Balloon to be performed
by:
A. Any aircraft owner
B. A certificated LSA Repairman – Maintenance (Balloon)
C. Any A&P mechanic only
D. A Designated Pilot Examiner
Rationale: Only an LSA Repairman – Maintenance with a rating for balloons
can legally perform and approve maintenance.
,5. What is the function of the parachute valve on a hot-air balloon?
A. Adds more fuel to the burner
B. Releases hot air to control descent
C. Measures envelope temperature
D. Seals the fuel tank
Rationale: The parachute valve releases hot air from the top of the balloon,
allowing descent or landing control.
6. Which FAA regulation governs the certification and maintenance of
Light-Sport Aircraft?
A. Part 61
B. Part 65
C. Part 43
D. Part 145
Rationale: FAA Part 65 outlines certification requirements for Repairmen and
mechanics, including LSA Repairmen.
7. What is the minimum number of flight hours a balloon repairman must
have to qualify for a maintenance rating?
A. 10
B. 25
C. None required for maintenance rating
D. 50
, Rationale: The maintenance rating focuses on training in aircraft systems
and maintenance procedures, not flight time.
8. Which of the following is a primary balloon system?
A. Landing gear system
B. Burner and fuel system
C. Hydraulic system
D. Electrical starter system
Rationale: The burner and fuel system are essential for controlling lift and
temperature in a hot-air balloon.
9. What fuel is most commonly used in hot-air balloons?
A. Jet A
B. Avgas
C. Propane
D. Kerosene
Rationale: Propane is used because it is efficient, readily available, and
provides sufficient heat energy.
10. The pilot light on a balloon’s burner system serves what function?
A. Measures altitude
B. Ignites the main burner flame
