Three letter identifiers are assigned to every flight service station and are annotated in Airport/Facilities Directories (A/FDs) and FAA Order 7350.6 as tie-in-facilities. flight data recorder. See FDR. flight service station. See FSS. flight simulator. A training device that duplicates the flight characteristics of an aircraft. The simulator looks like the flight deck or cockpit of a specific aircraft. All the controls and instruments are computer driven, and they duplicate those in the aircraft. The controls have the same feel, and the instruments give the same indications as those in the real aircraft. Flight simulators allow many different types of emergency situations to be simulated under safe conditions, so flight crews will know how to respond when a real emergency occurs. flight standards district office. See FSDO. flight test. Flight for the purpose of investigating the flight or operational characteristics of an aircraft or aircraft component, or evaluating an applicant for a pilot certificate or rating. flight time (aircraft records). 14 CFR Part 1: “The time from the moment the aircraft first moves under its own power for the purpose of flight until the moment it comes to rest at the next point of landing. (‘Block-to block’ time.)” flight visibility. 14 CFR Part 1: “The average forward horizontal distance, from the cockpit of an aircraft in flight, at which prominent unlighted objects may be seen and identified by day and prominent lighted objects may be seen and identified by night.” flight watch (air traffic control). A shortened term for use in air-ground contacts on the frequency of 122.0 MHz to identify the flight service station providing enroute flight advisory service (EFAS). flint lighter (welding equipment). A device used to light an oxy-gas welding torch. The lighter consists of a small piece of flint that can be rubbed against a piece of rough, hardened steel. A metal cup behind the steel prevents the flame from reaching out and burning anything as the torch is being lit. flip-flop (digital electronic building block). A digital building block having two stable states, used to store information. A flip-flop is made of two cross-coupled NAND or NOR gates that act as a latch. The output of each gate is applied to the input of the other. floated battery. A storage battery permanently installed across the output of a generator. The generator carries the normal electrical load and keeps the battery fully charged at all times. The battery supplies current to help the generator when the electrical load is unusually high. floating ground (electrical equipment). See chassis ground. flqoat-type carburetor. A type of carburetor used on reciprocating engines in which the fuel-metering force is produced by a float-operated needle valve that keeps the fuel level a constant distance below the edge of the discharge nozzle. flock. Pulverized wool or cotton fibers mixed with an adhesive. Flock can be sprayed on metal to produce a velvet-like protective finish. It can also be bonded to wire screen and used as a filtering element for certain types of air filters. |
