Aviation Machinist Mate Week 2 Assgn
With All Answers
What are the five Electricity Terms? - correct answer- Electricity, Voltage,
Amperage, Resistance, Watt.
Electricity - correct answer- The physical phenomena arising from the existence and
interaction of an electrical charge.
Voltage/Electromotive Force (EMF) - correct answer- The amount of force being
applied to a circuit to produce an electron flow.
Amperage - correct answer- The quantity of electricity flowing through the circuit
(Current Flow).
Resistance - correct answer- The opposition of the flow of electrons offered by a
device or material. (Ohm's)
Watt - correct answer- The measurement of electrical work done.
What are the two Forms Of Electricity? - correct answer- Static And Dynamic
Static Electricity - correct answer- Electricity at rest, produced by friction, and is not
easily measured nor is it controllable or usable.
Dynamic Electricity - correct answer- The practical form of current flow that is used
in everyday life. Easily produced, measured and controlled.
What are the methods of producing Dynamic Electricity? - correct answer-
Mechanical, Chemical, Thermal, and Pressure.
Mechanical Method Of Producing Dynamic Electricity - correct answer- Produced by
rotating a magnetic field through another magnetic field.
Chemical Method Of Producing Dynamic Electricity - correct answer- Produced by
surrounding two or more metallic plates with a chemical electrolyte.
Thermal Method Of Producing Dynamic Electricity - correct answer- Produced by
joining two dissimilar metals and applying heat.
, Pressure Method Of Producing Dynamic Electricity - correct answer- Produced by
applying pressure to quartz which will produce an electron flow.
What are the two types of Electricity (Current Flow)? - correct answer- Direct
Current (DC) and Alternating Current (AC).
Direct Current (DC) - correct answer- Current that is a steady flow in one direction
only and is produced by a DC generator, or chemically.
Alternating Current (AC) - correct answer- A current flow that reverses direction at
specific intervals, defined as Hertz/Cycles. (Only produced by a AC generator).
What must always be done to guard against the danger of static electricity during
servicing and maintenance? - correct answer- Ensure that the Aircraft is grounded!
Prior to applying external power to an aircraft, what should you ensure has been
checked? - correct answer- That all the switches are in the SAFE, OFF, or NORMAL
position.
What does a Multimeter Measure? - correct answer- Voltage, Current, and
Resistance.
What is the purpose of the Engine Electrical System? - correct answer- To provide
electrical power to the engine performance indicators.
Engine Speed Indicating System - correct answer- Provides a visual indication of
compressor rotor revolutions per minute (RPM).
Tachometer Generator - correct answer- Mounted and splined to the accessory
gearbox.
Engine Temperature Indicating System - correct answer- Provides a visual
indication of the engine gas temperature (EGT).
What two metals are used in a Thermocouple? - correct answer- Alumel and
Chromel, which when heated create a small voltage.
Fuel Flow Indicating System - correct answer- Indicates the amount of fuel being
consumed by the engine in pounds-per-hour (PPH).
Oil Pressure Indicating System - correct answer- Provides a visual cockpit indication
of engine oil pressure in pounds-per-square-inch (PSI).
Engine Fire Detection System - correct answer- Will alert the pilot of and engine bay
fire or overheat condition.
If the equipment is a transmitter it is mounted... - correct answer- On the Engine.
If the equipment is an indicator it is... - correct answer- In the Cockpit.
