solution
electricity - -Physical Phenomena arising from the existence and interaction of the electrical
charge
-voltage - -the amount of force being applied to a circuit to provide electron flow
-Amperage - -Quantity of electricity flowing through the circuit
-resisitance - -the opposition to the flow of electrons offered by a device or material
-what are the 2 forms of electricity - -Dynamic and Static
-what are the 4 methods of producing dynamic electricty - -mechanical chemical thermal and
pressure
-what are the 2 types of electricity - -direct current and alternating current
-what is the purpose of the multimeter - -Measure voltage, current and resistance.
-what must always be don't to guard against the dangers of static electricity during servicing
and maintenance - -Ensure all switches are Safe Off or Normal positions
-what is purpose of the engine electrical system - -To provide electrical power to the engine
performance indicators
-what provides a visual cockpit indication of compressor rotor RPM - -Tachometer
-what us the purpose of the engine temperature indicating system - -provides a visual
indication of the engine exhaust gas temperature
-what is the purpose of the fuel flow indicating system - -indicates the amount of fuel being
consumed by the engine in PPH
-what is the purpose of the engine ire detection system - -to alert the pilot of a engine bay fire
or overheating
-what is the purpose of the ignition system - -provides a high energy spark in the engine ignitor
plug and initiates the combustion section
-what is the purpose of the transformer exciter - -steps up the input voltage to the rated
output voltage
, -what are the 2 greatest hazards of the ignition system - -the electrical out is lethal and the
insulation material maybe radioactive
-State the purpose of the apu - -supplies bleed air (pneumatic pressure) for main engine
starting which is available at the start bypass valve
-give a description of the APU - -a small gas turbine engine located within the airframe of the
aircraft

& Accelerator, Oil Pump Assembly, Hydraulic starter, and speed sensor
-How may the APU be started - -Starting is accomplished by hydraulically using an aircraft
mounted hydraulic accumulator
-the safety control system includes 2 safety features to shut down the APU Automatically what
are they? - -Automatically shuts down when oil pressure falls below min Specified limits turbine
exceeds Max RPM or Temp
-what maintenance may be preformed on the APU by Organizational Level Maintenance - -
Periodic Inspections or Replacement of components complete removal and replacement of the
APU
-state the purpose of the engine lubrications system - -to provide an adequate supply of clean
oil to the bearings and gears at the right temperature
-state the two types of lubrication systems - -scavenge and pump
-what type of lubrication system has an external oil tank - -Axial Flow Engines
-what is the purpose of the reservoir/ oil tank - -stores the engines oil supply
-what controls the air pressure in the lubrication system - -Vent
-what type of valves allow for an alternate path of flow - -Bypass Valve
-what is the purpose of a pump - -creates a flow to volume of fluid
-state the purpose of filters - -removes contamination from lubrication
