Aviation Terms
| Title | Description |
| F | Foxtrot or Fox |
| FAA | Federal Aviation Administration. The entity responsible for regulation of aviation in the United States. |
| FADEC | Full Authority Digital Engine Control. This is a latest technology for throttle to engine control - more efficient, responsive and environmentally friendly. |
| FAR | Federal Aviation Regulations. Rules prescribed by the Federal Aviation Administration (FAA) governing all aviation activities in the United States. The FARs are part of Title 14 of the Code of Federal Regulations (CFR). A wide variety of activities are regulated, such as airplane design, typical airline flights, pilot training activities, hot-air ballooning, lighter than air craft, man-made structure heights, obstruction lighting and marking, and even model rocket launches and model aircraft operation. The rules are designed to promote safe aviation, protecting pilots, passengers and the general public from unnecessary risk. |
| FBO | Fixed Base Operator (or Fixed Base of Operations)- a passenger terminal and fueling station for business jets and general aviation aircraft. |
| Feather | To rotate the pitch of the propeller blades until they are oriented directly into the airflow, providing the least air resistance and no thrust. The propeller is usually feathered when an engine fails. |
| Federal Aviation Regulation | FARs. Rules prescribed by the Federal Aviation Administration (FAA) governing all aviation activities in the United States. The FARs are part of Title 14 of the Code of Federal Regulations (CFR). A wide variety of activities are regulated, such as airplane design, typical airline flights, pilot training activities, hot-air ballooning, lighter than air craft, man-made structure heights, obstruction lighting and marking, and even model rocket launches and model aircraft operation. The rules are designed to promote safe aviation, protecting pilots, passengers and the general public from unnecessary risk. |
| Federal Excise Tax | FET. Fees imposed by all levels of government on producers, manufacturers and importers of goods and activities. Private operators pay a fuel tax, while commercial firms pay taxes based on the amount of property transported. Passenger taxes are based on segments of the flight, a head tax and/or a percentage of the fee collected for travel. |
| Ferry Flight | A non-revenue flight for the purpose of returning an aircraft to base, positioning an empty aircraft, or moving an aircraft to and from a maintenance base. |
| FET | Federal Excise Tax. Fees imposed by all levels of government on producers, manufacturers and importers of goods and activities. Private operators pay a fuel tax, while commercial firms pay taxes based on the amount of property transported. Passenger taxes are based on segments of the flight, a head tax and/or a percentage of the fee collected for travel. |
| Final Assembly | Putting all the pieces together - much like a car assembly line. The parts come together and an airplane exits in a roll-out. |
| Finance Lease | Also known as a capital lease, is defined when one of the following conditions are met: 1) at the end of the lease term the Lessee has the option to purchase the aircraft at an agreed price. 2) the lease payments are more than 90% of the market value of the aircraft. 3) the term of the lease is over 75% of the aircraft's usable life. With a finance lease the aircraft appears on the Lessee's balance sheet, as it is viewed as a purchase. A finance lease is a type of dry lease. |
| Fixed Operating Cost | Expenses that are incurred whether the aircraft is flying or not. These costs can include crew salaries, hangar expenses, insurance, recurrent crew training, aircraft modernization, refurbishing, computer maintenance program, navigational chart service, and aviation weather service. |
| Flaperon | A control surface on an aircraft wing functioning both as a flap and as an aileron. |
| Fleet | A number of aircraft operating together or under the same ownership. |
| Flight Attendant | Also referred to as cabin crew (historically known as stewards/stewardesses or air hosts/hostesses) are members of an aircrew employed by airlines and operators primarily to ensure the safety but also the comfort of passengers aboard commercial flights and on select business jet aircraft. Flight attendants are almost always on board heavy jet flights, but less likely to be on midsize and light jet charters. |
| Flight Cycle | One takeoff and landing of an aircraft is referred to as one flight cycle. This is one measurable used to calculate the "newness" or the "wear and tear" of an aircraft. Along with flight hours, used to determine appropriate timing for maintenance checks. |
| Flight Hours | The number of hours an aircraft has flown during its life. This is one measurable used to calculate the "newness" or the "wear and tear" of an aircraft. Along with flight cycles, used to determine appropriate timing for maintenance checks. |
| Flight Level | Flight level is the nominal altitude of an aircraft referenced to a standard pressure datum, as opposed to the real altitude above mean sea level. |
| Forward | At, toward, or of the front, or forepart of an aircraft. |
| Fractional Ownership | Fractional ownership is a popular investment in the private air travel arena. Essentially, a flyer purchases a partial interest in an aircraft that is operated by an aviation company as part of its fleet. As an owner, the flyer has the right to use any comparable aircraft in the fleet, on demand, for a predetermined number of hours each year. Generally speaking, fractional ownership is said to be for those who fly between 50 and 200 hours per year. A typical agreement might include 100 hours of flying time per year for each 1/8 share. The fractional provider manages the aircraft and the rest of its fleet, providing pilots, maintenance, insurance, catering and other services. |
| Fractional Share | A percentage of ownership in a Fractional Ownership program. Usually in increments of 1/8 shares. These percentages allow for a certain amount of flight hours on a jet comparable to the jet a flyer owns a portion of. |
| FSDO | Flight Standards District Offices. FSDOs are regional offices of the United States Federal Aviation Administration. There are about 82 such regional offices nationwide. |
| Fuel Burn | The amount of fuel an aircraft consumes during its various operations. |
| Fuel Surcharges | An extra percentage charge added to the total cost of a trip or delivery due to the increased price of fuel. |
| Fuselage | The central body of an aircraft, to which the wings and tail assembly are attached and which accommodates the crew, passengers, and cargo. |
