Course DescriptionsAVIA165 Hydraulic and Pneumatic Power SystemsCredits: 3Prerequisites: noneThis course introduces hydraulic and pneumatic power systems,which are used to operate many of the vital systems, such aslanding gear retraction, brakes, and powered flight controls. Thestudents will inspect, check, service, troubleshoot, and repairthese systems and will learn to work safely with these fluidsand their pressurized containers.AVIA170 Aircraft Landing Gear Systems/Position andWarning SystemsCredits: 2Prerequisites: noneThis course introduces landing gear systems, which are subjectto greater stresses than any other airframe system; therefore, thestudent must completely understand these vital components.This section includes lectures and schematic diagrams of thesesystems, exploded views of the assemblies, and illustrationsof the workings of brake control systems, and the requiredmaintenance. The different systems are covered in three areas:anti-skid brakes and their systems, electrical circuits andlanding gear actuation, and warning systems for instrumentsthat indicate and measure movement.AVIA205 Aircraft Electrical SystemsCredits: 2Prerequisites: noneThis course introduces electricity and airframe electricalsystems. Basic electricity is taught along with typical airframeelectrical circuits. The student will learn both general diagramsymbols and specific electrical systems along with industryacceptedmethods of installation and proper testing equipmentused.AVIA210 Aircraft Fuel Systems/Fire Protection Systems/Iceand Rain Control SystemsCredits: 3Prerequisites: noneThis course introduces the complex system of tanks, valves,and pumps of modern aircraft. The student will learn thesesystems in order to service them efficiently and safely. Thissection describes the various aircraft fuels and explains the fuelsystem requirements. This course also introduces fire protectionsystems and shows that fire is an ever possible danger in anaircraft, and that the student must be aware of the nature offire and the appropriate methods and agents for detecting andextinguishing aircraft fires. This section explains how theseprotection systems work. This course also covers ice and raincontrol systems.AVIA215 Cabin Atmosphere Control SystemsCredits: 2Prerequisites: noneThis section covers maintaining an aircraft cabin environmentwith the proper pressure, temperature, humidity, and airmovement, which is more than a matter of comfort; it is alsoa safety factor. This section backs up its discussion of thesesystems by starting with an explanation of “Human Needsin Flight” and how the atmosphere, the chemistry of oxygen,and the physics of heat, temperature, and pressure relate tothis topic.AVIA220 Aircraft Instrument Systems/Communication andNavigation SystemsCredits: 3Prerequisites: noneThis course introduces instrument systems that are needed toprovide the flight crew with data relating to the operating of thevarious flight and powerplant systems. This section describesthe instruments and the basic operating principles of the systemsthat run them. The student will learn the installation andmaintenance of these systems. Aircraft depend upon electronicnavigation and communication equipment. The student willlearn his or her responsibility for determining the conditionof the installed equipment and its interface with the aircraftitself. The student will also receive a detailed discussion ofcommunication and navigation systems, as well as basic radiotheory, to provide an understanding of how these systemsshould work.AVIA225 Development of Aircraft PowerplantsCredits: 2Prerequisites: noneThis course will introduce the student to the development ofaircraft powerplants from the Wright brothers’ first engine, tothe modern piston, turbine, and turboprop engines that areused on aircraft and helicopters throughout the world today.AVIA230 Reciprocating Engines and SystemsCredits: 6Prerequisites: noneThis course introduces aircraft powerplants that are of thereciprocating (piston) type. This section introduces the studentto the different types of reciprocating engines, which includethe detailed material that covers the step-by-step, hands-onprocedures for reciprocating engine inspection, troubleshooting,repair, and overhaul. The course includes the operation of fuelmetering components, induction and exhaust systems, heatdissipation, and starter systems.UM-Helena College of Technology 2011 - 2012 Academic Catalog 89
