BLOCK VI - Avionics Division|2026
UPDATE | QUESTIONS AND ANSWERS |
WITH COMPLETE SOLUTION
Define and describe Ohm's Law. - ANSWERS-Current through a
conductor between two points is directly proportional to the voltage
across the points.
Explain the difference between NC and NO contacts on a switch. -
ANSWERS-NC - Normally Closed; circuit breaker
NO - Normally Opened; push button or switch
Explain the basic measurement functions of a Digital Multimeter. -
ANSWERS-Resistance (ohms)
Volts AC
Volts DC
Current AC
Current DC
Frequency(Hz)
*some have continuity and diode checks etc.
,Describe Huntron and state its purpose. - ANSWERS-MTR compares
signal with normal routine of card circuitry through the use of
software box with computer. No power coming from components.
Describe for what an oscilloscope is utilized. - ANSWERS-Used to
troubleshoot & align electronic equipment by observing and analyzing
wave form shape, amplitude and duration.
Describe what ESD is and what measures must be followed to prevent
damage to ESD items. - ANSWERS-Electrostatic Discharge - a transfer
of electrostatic charge between objects at different potentials cause
by direct contact or induced by an ESD field.
-No prime generator in area of ESD (Styrofoam, plastic, vinyl)
-Personal grounding & apparel (smock, sleeves, personal ground)
-Use of anti-static materials (protective bags, labels, tape)
Explain the pre-operation check procedures when using an ESD mat. -
ANSWERS-Inspect mat for material condition, corrosion and
cleanliness. Use a damp cloth if cleaning is required and dry prior to
storage. Check strap for resistance and conductivity.
*ESD issues can lead to intermittent failures and "ghost gripes".
List the ratings which comprise the Avionics Division. - ANSWERS-AE
AT - ATO/ATI
Name three requirements of a basic electrical circuit. - ANSWERS-•
Voltage source
• Some type of load
, • A conducting pathway
Describe the direction of current flow. - ANSWERS-It is determined by
the polarity flowing from positive to negative.
Explain how the following circuit protectors work. - ANSWERS-a. Fuses
(Simplest) - melts internal element/wire before it gets to the other side
of the system.
b. Circuit breakers - Interrupts circuit. Can be used multiple times,
reliable and tamper proof.
Alternating Current - ANSWERS-Changes in amplitude and reverses
direction at regular intervals.
Direct Current - ANSWERS-Electricity flows in one direction.
Voltage - ANSWERS-Electrical force or potential difference in volts.
Current - ANSWERS-(Amperes) Electron flow past a reference point.
Resistance - ANSWERS-(Ohms) amount of current that flows through
an electromotive force.
Frequency - ANSWERS-Number of times a wavelength repeats or
completes a cycle.
