AVMT 250 (General Oral) exam with questions and answers (100% solved)
Explain the basic concept of digital logic, including RAM, ROM, NVRAM, logic gates, inverters,
rectifiers, and flip flops. (AM.I.A.K22) - ✔✔✔-Transistors are used in digital electronics to
construct circuits that act as digital logic gates. The purpose and task of a device is achieved by
manipulating electric signals through the logic gates. Thousands, and even millions, of tiny
transistors can be placed on a chip to create the digital logic landscape through which a
component's signals are processed.
Flip-flop - ✔✔✔-An electrical circuit that can store a single binary signal, either a 1 or 0. The
binary state can change based on the input signal.
How are CPCs applied to aircraft structures? (A.M.I.G.K10) - ✔✔✔-CPCs are normally applied
with high-pressure spray equipment that creates a fog of the CPC material inside the aircraft
structure. Long spray wands are used to reach difficult-to-access areas.
How can you get information on subscribing to the Airworthiness Directives? (A.M.I.I.K9) -
✔✔✔-Contact FAA, Manufacturing Standards Section (AFS-613), PO Box 26460, Oklahoma City,
OK 73125-0460.
How is information on an AD disseminated? (A.M.I.I.K9) - ✔✔✔-It is printed and distributed by
first class mail to the registered owners and certain known operators of the product(s) affected.
How is information on an emergency AD sent to the owner or operator of an affected aircraft or
other product? (A.M.I.I.K9) - ✔✔✔-By first-class mail, telegram, or other electronic method.
How is rust removed from a highly stressed metal part? (A.M.I.G.K7) - ✔✔✔-By glass bead
blasting, by careful polishing with mild abrasive paper, or by using fine buffing compound on a
cloth buffing wheel.
How is the welding flux removed from a piece of aluminum that has been gas-welded?
(A.M.I.E.K12) - ✔✔✔-It should be removed by scrubbing it with hot water and a bristle brush.

How may rust be removed from a highly stressed metal part? (A.M.I.G.K7) - ✔✔✔-By glass bead
blasting, by careful polishing with mild abrasive paper, or by using fine buffing compound on a
cloth buffing wheel.
In what increments can a vernier micrometer caliper be read? (A.M.I.E.K6) - ✔✔✔-One ten
thousandth (0.0001) inch
Inverter - ✔✔✔-When used as a logic function, converts a 1 to a 0, or a 0 to a 1.
Is it mandatory that the information in an AC be complied with? (A.M.I.I.K9) - ✔✔✔-No, this
information is advisory in nature.
Is the size of a flexible hose determined by its inside or its outside diameter? (A.M.I.D.K1) -
✔✔✔-By its inside diameter.
Is the size of a rigid fluid line determined by its inside or its outside diameter? (A.M.I.D.K1) -
✔✔✔-By its outside diameter.
Logic Gates - ✔✔✔-Provide a set output signal based on one or more input signals. The input
signal is either voltage (referred to as True, Logic 1, or Yes), or no voltage (referred to as False,
Logic 0, or No). The basic logic gates are AND, OR and NOT.
May all of the information in AC 43.13-1B be used as approved data? (A.M.I.I.K9) - ✔✔✔-No, it
is acceptable, but not necessarily approved data.
NVRAM - ✔✔✔-Non-volatile random access memory is random access memory that is retained,
even when power is lost.
Of what material are most low-pressure rigid fluid lines made? (A.M.I.D.K1) - ✔✔✔-1100-1/2
hard or 3003-1/2 hard aluminum alloy tubing.
