1Under 14 CFR § 61.23, what medical certificate requirement applies to a pilot exercising the privileges of a Private Pilot Certificate with a Lighter-than-Air category, Gas Balloon class rating?
A.No medical certificate is required; the pilot may exercise privileges by holding a valid driver's license or self-certifying medical fitness.
B.A Third-Class Medical Certificate is required, valid for 60 calendar months for pilots under age 40.
C.A BasicMed qualification is required, requiring a physical examination every 48 months.
D.A Second-Class Medical Certificate is required for all balloon operations carrying passengers.
Explanation: Under 14 CFR § 61.23(b)(2), a person holding or applying for a pilot certificate with a balloon rating is not required to hold an FAA medical certificate. However, under 14 CFR § 61.53, pilots must self-certify that they have no known medical condition that would make them unable to operate the balloon safely.
2What is the minimum age requirement under 14 CFR § 61.103 to be eligible for a Private Pilot Certificate with a Lighter-than-Air category, Gas Balloon class rating?
A.16 years of age
B.17 years of age
C.18 years of age
D.15 years of age
Explanation: Under 14 CFR § 61.103(a), an applicant for a private pilot certificate for a rating in a glider or balloon must be at least 16 years of age (compared to 17 years of age for powered aircraft ratings).
3To maintain currency as pilot in command of a gas balloon under 14 CFR § 61.56, within what timeframe must a private pilot complete a flight review?
A.24 calendar months
B.12 calendar months
C.36 calendar months
D.6 calendar months
Explanation: Under 14 CFR § 61.56(c), no person may act as pilot in command of an aircraft unless, within the preceding 24 calendar months, that person has accomplished a flight review given in an aircraft for which that person is rated by an authorized instructor.
4According to 14 CFR § 61.57, what recent flight experience is required for a private pilot to act as pilot in command of a gas balloon carrying passengers?
A.3 takeoffs and landings in a gas balloon within the preceding 90 days
B.5 takeoffs and landings in any balloon within the preceding 60 days
C.3 hours of flight time in a gas balloon within the preceding 30 days
D.1 flight of at least 2 hours duration within the preceding 12 calendar months
Explanation: Under 14 CFR § 61.57(a), to carry passengers, a pilot must have made at least 3 takeoffs and landings within the preceding 90 days in an aircraft of the same category, class, and type (if a type rating is required). For gas balloon pilots, these must be in a gas balloon.
5Under 14 CFR § 91.113, which aircraft has the right-of-way over all other engine-driven aircraft and gliders?
A.A balloon
B.A glider
C.An airship
D.An aircraft in distress
Explanation: Under 14 CFR § 91.113(e), a balloon has the right-of-way over any other category of aircraft, except an aircraft in distress which has right-of-way over all other air traffic under § 91.113(c). Among non-distress aircraft, balloons take priority over gliders, airships, and powered aircraft.
6Which general rule under 14 CFR § 91.119 applies to minimum safe altitudes for operating a balloon over congested areas?
A.Except when necessary for takeoff or landing, a balloon must maintain 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet, because § 91.119(d) relief is written only for helicopters, powered parachutes, and weight-shift-control aircraft.
B.A balloon may operate over congested areas at any altitude allowing an emergency landing without undue hazard to persons or property on the surface.
C.Balloons are prohibited from flying over congested areas under all circumstances.
D.A balloon must maintain at least 500 feet above the surface at all times except during takeoff.
Explanation: Section 91.119(d) is captioned 'Helicopters, powered parachutes, and weight-shift-control aircraft' and grants lower-altitude relief only to those three. A balloon therefore meets the congested-area minimum in § 91.119(b): 1,000 feet above the highest obstacle within a 2,000-foot horizontal radius, except when necessary for takeoff or landing. Paragraph (a) applies as well, requiring an altitude permitting an emergency landing without undue hazard.
7What are the basic VFR weather minimums for operating a gas balloon in Class G airspace below 1,200 feet AGL during daylight hours under 14 CFR § 91.155?
A.1 statute mile flight visibility and clear of clouds
B.3 statute miles flight visibility and 500 feet below clouds
C.1 statute mile flight visibility, 500 feet below, 1,000 feet above clouds
D.5 statute miles flight visibility and clear of clouds
Explanation: Under 14 CFR § 91.155(a), day VFR operations in Class G airspace at 1,200 feet or less above the surface require at least 1 statute mile flight visibility and the requirement to remain clear of clouds.
8Under 14 CFR § 91.155, what distance from clouds must a gas balloon maintain when operating VFR in Class E airspace below 10,000 feet MSL?
A.500 feet below, 1,000 feet above, and 2,000 feet horizontal
B.1,000 feet below, 1,000 feet above, and 1 statute mile horizontal
C.Clear of clouds
D.500 feet below, 500 feet above, and 1,000 feet horizontal
Explanation: Under 14 CFR § 91.155(a), in Class E airspace below 10,000 feet MSL, VFR cloud distance requirements are 500 feet below, 1,000 feet above, and 2,000 feet horizontal from any cloud, with 3 statute miles visibility.
9What is the minimum flight visibility and cloud clearance required for VFR balloon flight within Class B airspace under 14 CFR § 91.155?
A.3 statute miles visibility and clear of clouds
B.3 statute miles visibility, 500 feet below, 1,000 feet above clouds
C.5 statute miles visibility and 1,000 feet clear of clouds
D.1 statute mile visibility and clear of clouds
Explanation: Under 14 CFR § 91.155(a), VFR flight within Class B airspace requires 3 statute miles flight visibility and that the aircraft remain clear of clouds.
10When flying over open water or sparsely populated areas, what minimum distance from any person, vessel, vehicle, or structure must a balloon pilot maintain under 14 CFR § 91.119(c)?
A.500 feet
B.1,000 feet
C.200 feet
D.100 feet
Explanation: Under 14 CFR § 91.119(c), over open water or sparsely populated areas, an aircraft (including a balloon) may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.

FAA PBG Knowledge Test — Private Pilot Balloon - Gas Study Tips from Top Performers

1Master gas lift calculations: Understand the difference between gross lift and net payload lift for helium (~62 lbs/1000 cu ft net) versus hydrogen (~68-71 lbs/1000 cu ft net).
2Memorize 14 CFR Part 91 right-of-way rules: Balloons have right-of-way over all other engine-driven aircraft and gliders.
3Understand gas expansion laws (Boyle's and Charles's Laws): As a gas balloon ascends, ambient pressure drops causing the lifting gas to expand, requiring an open appendix to prevent overpressurization.
4Study thermal superheating: Direct sun heating the lifting gas increases its temperature above ambient air, increasing lift temporarily without changing mass; cooling at sunset causes loss of lift.
5Practice numerical problems: Solve density altitude, ballast drop percentage required for acceleration arrest, wind drift velocity vectors, and cloud clearance distance rules.

Frequently Asked Questions

What is the FAA PBG Knowledge Test?

The FAA PBG Knowledge Test is the official FAA written examination required to obtain a Private Pilot Certificate with a Lighter-than-Air Category, Gas Balloon Class Rating under 14 CFR Part 61.

How many questions are on the official FAA PBG exam and what is the passing score?

The official exam contains 60 multiple-choice questions with a 2.5-hour (150 minutes) time limit. A score of 70% or higher (at least 42 correct answers out of 60) is required to pass.

Does a gas balloon pilot need an FAA Medical Certificate?

Under 14 CFR § 61.23(b)(2), a person holding or applying for a pilot certificate with a balloon rating is not required to hold an FAA medical certificate. However, pilots must self-certify that they have no known medical condition that would make them unable to operate the balloon safely under 14 CFR § 61.53.

What is the main difference between gas balloon and hot air balloon flight controls?

Hot air balloons control altitude using burners to heat envelope air, whereas gas balloons use unheated lifting gases (helium or hydrogen) and control altitude by venting gas through a maneuvering valve to descend or discharging ballast (dry sand or water) to ascend.
