1. 1A commercial hot-air balloon pilot will carry paying sightseeing passengers, rather than provide flight training. What is the minimum class of FAA medical certificate required for this operation?

   1. A. First-class medical certificate
   2. B. Second-class medical certificate
   3. C. Third-class medical certificate
   4. D. No medical certificate required

   Answer: B

   Explanation: Section 61.23(a)(2) says, "Must hold at least a second class medical certificate" when exercising "privileges of a commercial pilot certificate with a balloon class rating for compensation or hire" except the flight-training exception. This passenger flight requires at least second class.

2. 2For a balloon buoyancy calculation, the surrounding air displaced by the envelope weighs 5,000 pounds. Before subtracting the weight of the heated air and balloon assembly, what upward buoyant force does the displaced air provide?

   1. A. 2,500 pounds-force
   2. B. 5,000 pounds-force
   3. C. 7,500 pounds-force
   4. D. 10,000 pounds-force

   Answer: B

   Explanation: The handbook states, "The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the object." The surrounding air therefore provides 5,000 pounds-force. Halving, adding half again, or doubling the displaced weight misapplies the relation.

3. 3At a proposed launch site, fog develops overnight under a clear sky with light wind as the ground loses heat and cools the adjacent moist air. Which fog type best fits this formation mechanism?

   1. A. Advection fog
   2. B. Upslope fog
   3. C. Steam fog
   4. D. Radiation fog

   Answer: D

   Explanation: The handbook states, "Radiation fog forms after the Earth has radiated back to the atmosphere the heat gained during daylight hours." Clear skies, moist air, and light wind favor this overnight surface-cooling mechanism.

4. 4For the planned conditions, a balloon may operate at a gross weight of 1,400 pounds. Basic empty weight is 500 pounds, fuel weighs 180 pounds, removable equipment weighs 40 pounds, and the pilot weighs 180 pounds. What maximum passenger weight remains available?

   1. A. 500 pounds
   2. B. 680 pounds
   3. C. 860 pounds
   4. D. 1,000 pounds

   Answer: A

   Explanation: The handbook describes useful load as "the basic empty weight of the aircraft (found in the flight manual for each balloon) subtracted from the maximum allowable gross weight." The 900-pound useful load must include fuel, equipment, and pilot: 1,400 − 500 − 180 − 40 − 180 = 500 pounds. Omitting fuel gives 680, omitting fuel and pilot gives 860, and omitting empty weight gives 1,000.

5. 5A pilot exceeds the balloon flight manual's maximum climb rate during launch. What dangerous envelope behavior is described in the FAA handbook as floating the top?

   1. A. Side distortion reduces the volume of retained heated air
   2. B. Airflow over the lower envelope creates a downward force
   3. C. Air pressure pushes the top cap down, allowing uncontrolled descent
   4. D. Increased fabric porosity allows more heated air to escape

   Answer: C

   Explanation: The handbook describes floating the top as a condition where "the air pressure created by the climb may push the top cap of the balloon down, causing an out-of-control descent." Side distortion, downward aerodynamic force, and porous-fabric heat leakage are real adjacent balloon effects, but they are not this top-cap displacement caused by excessive climb.

6. 6A balloon pilot estimates the distance between two landmarks measured 2 inches apart on a 1:500,000 sectional chart. Approximately what ground distance does this represent?

   1. A. 6.9 nautical miles
   2. B. 8.0 nautical miles
   3. C. 13.7 nautical miles
   4. D. 27.4 nautical miles

   Answer: C

   Explanation: The handbook gives the sectional scale as "1 inch = 6.86 nautical miles (NM)". Two inches represent 13.72 NM, about 13.7. Using only one inch gives 6.9; mixing the approximate 8 statute miles per inch with nautical miles gives 8.0; doubling the distance again gives 27.4.

7. 7A balloon pilot recognizes a serious weather risk but dismisses it with the thought that such an accident happens to other pilots, never to the pilot personally. Which hazardous attitude best describes that reasoning?

   1. A. Resignation
   2. B. Invulnerability
   3. C. Anti-authority
   4. D. Impulsivity

   Answer: B

   Explanation: Figure 1-5 pairs invulnerability with the antidote "It could happen to me." The pilot's belief in personal immunity fits invulnerability, rather than helplessness, rejection of rules, or acting without thought.

   Reference: Balloon Flying Handbook — Chapter 1: Introduction to Balloon Flight Training — p.1-8, Figure 1-5, Invulnerability and antidote

8. 8A balloon's vent control line has failed, leaving burner control available but no normal vent control. Following the flight manual's emergency guidance, which landing-site characteristic should the pilot favor?

   1. A. The site with the firmest usable ground surface
   2. B. The site with the closest usable recovery-road access
   3. C. The site with the highest usable terrain elevation
   4. D. The site with the largest usable open landing area

   Answer: D

   Explanation: For loss of the vent-control line, the handbook advises the pilot to "land in the largest area possible." Extra landing area accommodates reduced control, rebound, and dragging. Surface firmness, road access, and terrain elevation are real site characteristics but do not supply that required room. The applicable flight-manual procedure remains controlling.

9. 9A U.S.-registered balloon's required pilot spends 45 continuous minutes at a cabin pressure altitude of 13,500 feet MSL. What is the minimum portion of that period for which §91.211 requires the pilot to use supplemental oxygen?

   1. A. The final 15 minutes
   2. B. The final 30 minutes
   3. C. The entire 45 minutes
   4. D. No portion of the 45 minutes

   Answer: A

   Explanation: Section 91.211(a)(1) requires oxygen above 12,500 through 14,000 feet "for that part of the flight at those altitudes that is of more than 30 minutes duration". Of 45 minutes, the last 15 exceed the initial 30-minute allowance.

   Reference: 14 CFR Part 91 — General Operating and Flight Rules — §91.211(a)(1)

10. 10Which appropriately rated pilot certificate authorizes its holder to give both flight and ground training toward a balloon pilot certificate without holding a separate flight instructor certificate?

    1. A. Private pilot certificate with lighter-than-air/balloon rating
    2. B. Sport pilot certificate with balloon operating privileges
    3. C. Commercial pilot certificate with lighter-than-air/balloon rating
    4. D. Student pilot certificate with a balloon solo endorsement

    Answer: C

    Explanation: Section 61.133(a)(2)(ii)(A) authorizes the appropriately rated commercial pilot to "Give flight and ground training in a balloon for the issuance of a certificate or rating". The private, sport, and student certificates listed do not themselves carry this commercial balloon-instruction authority.
