Glossary Flashcards
To terminate an operation prematurely when it is seen that the desired result will not occur.
Abort
In weather, the term used for the horizontal transport of heat by the wind.
Advection
The actual distance between an aircraft and the terrain over which it is flying.
Absolute altitude
AN FAA publication that informs the aviation public, in a systematic way, of nonregulatory material.
Advisory circular (AC)
An occurrence associated with the operation of an aircraft which takes place between the time any person boards the aircraft with the intention of flight and all such persons have disembarked, and in which any person suffers death or serious injury, or in which the aircraft receives substantial damage. (NTSB 830.2)
Accident
A reference publication for pilots.
Aeronautical Information Manual (AIM)
A regulatory notice sent out by the FAA to the registered owner of an aircraft informing him or her of a condition that prevents the aircraft from meeting its conditions for airworthiness. Compliance requirements will be stated in the AD.
Airworthiness directive (AD)
In weather, the change of the temperature of air without transferring heat. In the __________ __________, compression of the air mass results in the warming of the air; conversely, the expansion of the air mass results in cooling of the air.
Adiabatic process
The FAA __________ or any person to whom he or she has delegated authority in the matter concerned.
Administrator
A person who operates or travels in a balloon or airship.
Aeronaut
A systematic approach to the mental process, used by pilots to consistently determine the best course of action in response to a given set of circumstances.
Aeronautical Decision-Making (ADM)
The branch of science that deals with flight and with the operations of all types of aircraft.
Aeronautics
A device supported in the air by displacing more than its own weight of air.
Aerostat
An air traffic facility that provides pilot briefings and numerous other services.
Automated flight service station (AFSS)
Above ground level.
AGL
A device that is used or intended to be used for flight in the air.
Aircraft
An area of land or water that is used for landing and takeoff of an aircraft.
Airport
A pressure reading device that, when properly calibrated, indicates the height of the aircraft above mean sea level (MSL). An __________ is a required instrument in a balloon, as directed by 14 CFR Park 31, Airworthiness Standards: Manned Free Balloons.
Altimeter
The station pressure (barometric pressure at the location the reading is taken) which has been corrected for the height of the station above sea level.
Altimeter setting
Air surrounding the outside of a balloon envelope.
Ambient air
In weather, a wind that blows up the slope of a hill or mountain due to increased heating along the valley walls.
Anabatic winds
A maintenance team directed by 14 CFR part 91, section 91.409, which states that “no person may operate an aircraft unless, within the preceding 12 calendar months, it has had-(1) annual inspection…and has been approved for return to service…”
Annual inspection
A line attached to the top of most balloons to assist in inflation or deflation. Also called crown line or top handling line.
Apex line
__________ by the FAA Administrator or person authorized by the Administrator.
Approved
The Greek mathematician’s principle of buoyancy, which states than an object (a balloon) immersed in a fluid (the air) loses as much of its own weight as the weight of the fluid it replaces.
Archimedes’ Principle
Air Traffic Control
ATC
The continuous broadcast (by radio or telephone) of recorded non-control, essential but routine information in selected terminal areas.
Automatic Terminal Information Service (ATIS)
Continuous broadcast (by radio or telephone) of weather conditions at selected locations.
Automatic Weather Observing System (AWOS)
Gas ballooning term; used to control buoyancy, and therefore altitude, during flight. __________, usually in the form of sand or water is carried aloft by the gas balloon at launch. As the balloon pilot needs to adjust altitude, a small amount of __________ is jettisoned overboard, thereby reducing the gross weight of the balloon at that point in time. The balloon will then rise to a new pressure altitude, where it will remain until there is another dynamic change in the lift equation.
Ballast
A lighter-than-air aircraft that is not engine driven, and that sustains flight through the use of either gas buoyancy or an airborne heater.
Balloon
A national association for balloon pilots and enthusiasts in the United States, and affiliated with the National Aeronautic Association.
Balloon Federation of America (BFA)
A manual containing operating instructions, limitations, weight, and performance information, which must be available in an aircraft during flight. Portions of the __________ __________ are FAA approved.
Balloon flight manual
That portion of a hot air balloon that carries the pilot, passengers, cargo, fuel, and instruments,.
Basket
The valve on a propane burner that controls the flow of propane burned to produce heat.
Blast valve
Pronounced boh’ lin. A common knot that is easy to tie and until and will not slip.
Bowline knot
A measurement of heat. The amount of heat required to raise 1 pound of water from 60 to 61 °F.
Btu (British thermal unit)
In ballooning, when the balloon is zero weight and is neither climbing or falling.
Buoyancy
A common term meaning to activate the main blast valve and produce a full flame for the purpose of heating the air in the envelope.
Burn
Commonly used to describe a balloon that is permanently anchored to the ground.
Captive balloon
According to Title 14 of the Code of Federal Regulations: (1) As used with respect to the certification, ratings, privileges, and limitations of airmen, means a broad classification of aircraft. Examples include: airplane; rotorcraft; glider; and lighter-than-air aircraft; and (2) As used with respect to the certification of aircraft, means a grouping of aircraft based upon intended use or operating limitations. Examples include: transport, normal, utility, acrobatic, limited, restricted, and provisional (14 CFR part 1).
Category
The lowest broken or overcast layer of clouds or vertical visibility into an obscuration.
Ceiling
Code of Federal Regulations
CFR
If the pressure of a has is held constant and its absolute temperature is increased the volume of the gas will also increase. This principle is particular relevant in gas ballooning.
