A-stage - In composites, the initial stage of mixing thetwo parts of a thermosetting resin system together. Thematerial is soluble in some liquids and fusible.A chamber - One of the chambers of a pressure-typecarburetor regulator unit. A chamber regulates air-inletpressure from the air intake.A check - Primarily associated with large commercialaircraft, the lowest level of inspection in a ContinuousAirworthiness Maintenance Program. The entireprogram consists of A, C, and D checks.A&B system - An emergency brake design used insome larger multiple-disc brake systems. These brakeshave a number of cylinders, with alternate cylindersconnected either to the aircraft's "A" system or to theaircraft's "B" system. Normal brake actuation takesover if one system fails.ACP technician -An aircraft technician certified by theFederal Aviation Administration as having met theexperience and knowledge requirements forcertification. An A&P technician is qualified to returnlicensed United States airplanes to service afterperforming certain inspections and maintenanceprocedures. Increasingly referred to as AMTs (AviationMaintenance Technicians).A, B, C, D, E chambers - The five chambers that makeup a diaphragm-controlled unit of a pressure typecarburetor. Chamber A is regulated air-inlet pressure.Chamber B is boost venturi pressure. Chamber Ccontains metered fuel pressure. Chamber D containsunmetered fuel pressure. Chamber E is fuel pumppressure.A-battery - A dry cell battery with a voltage of 1.5 to6.0 volts and capable of supplying a reasonable amountof current.abbreviated briefing - In meteorology, a shortenedbriefing to supplement mass disseminated data.abbreviated IPR flight plans - An authorization byATC requiring pilots to submit only that informationneeded for the purpose of ATC. It includes only a smallportion of the usual IFR flight plan information. Incertain instances, this may be only aircraftidentification, location, and pilot request. Otherinformation may be requested if needed by ATC forseparationlcontrol purposes. It is frequently used byaircraft which are airborne and desire an instrumentapproach or by aircraft which are on the ground anddesire a climb to VFR-on-top.abeam - An aircraft is "abeam" a fix, point or objectwhen that fix, point, or object is approximately 90degrees to the right or left of the aircraft track. Abeamindicates a general position rather than a precise point.Aircraft Technical Book CompanyP.O. Box 270Tabernash, CO 80478http:llw.ACTechbooks.comA - absolute humidityabeam fix - A fix positioned approximately 90 degreesfrom a navaid along a route of flight.abnormal procedures training (APT) - The use offlight training devices to teach pilots how to handleprocedures such as engine failures, inflight fires, andother abnormal situations. This training is completedon the ground and is the safest means of allowing apilot to experience abnormal procedures.abort - To terminate a preplanned aircraft maneuver;e.g., an aborted takeoff.aborted start - In gas turbine engines, termination ofthe engine starting cycle when combustion (light-off)does not occur within a prescribed time limit.abradable seal - A general description of knife-edgeseals which can wear away slightly and still function.Such seals in a gas turbine engine abrade slightly toproduce a close fit.abradable shroud - Generally a honeycomb-typeturbine shroud ring set into the outer turbine case. Canabrade without engine degradation if the turbine bladescreep and contact the shroud.abrade - To scrape or wear away a surface or a part bymechanical or chemical action.abrasion - 1. An area of roughened scratches or marksusually caused by foreign matter between moving partsor surfaces. 2. The wearing or rubbing away of asurface by a substance used for grinding, grating,polishing, etc.abrasive - A substance used to wear away surfaces bythe use of friction. In grinding wheels, the abrasivesmost commonly used are silicon carbide or aluminumoxide.abrasive blasting - The removal of carbon and otherdeposits from machine parts using a high velocity blastof air that contains fine particles of abrasive sand, glassbead, or walnut shell.abscissa - The horizontal reference line of a graph orcurve by which a point is located with reference to asystem of coordinates.absolute altimeter - A radar altimeter used to indicatethe exact height of an aircraft over the terrain. See alsoradio altimeter.absolute altitude - The actual height above thesurface of the earth, either land or water.absolute ceiling - The maximum height above sea levelat which an aircraft can maintain level flight understandard atmospheric conditions.absolute humidity - The actual water vapor present in agiven volume of air.
