LGAV 3110 Midterm Exam, 2026 – Aviation Studies Study and
Review Material
DDG stands for
A. Designated Design Goals
B. Dispatch Deviation Guide
C. Deferral of Deteriorating Governors
D. Development of Destination Grounds - ANS✔✔ Dispatch Deviation Guide
True or False: Preventative maintenance is usually preformed at regular intervals - ANS✔✔ True
89% of aircraft components must be operated to failure before replacement or repair is done.
This results in the need for
A. Scheduled Maintenance
B. Unscheduled maintenance
C. Unique equipment and components
D. Infant mortality - ANS✔✔ Unscheduled maintenance
Reliability of a system is also referred to as the:
A. Reduction in maintenance service
B. Design-in level of perfection
C. Attainable level of entropy
D. None of the above - ANS✔✔ Design-in level of perfection
The design of aircraft systems or components is limited by
A. Physical entropy
, B. Natural entropy
C. Man-made entropy
D. A & B
E. B & C - ANS✔✔ B & C
Equipment redundancy, LRUs, and MELs are designed to
A. Stabilize the erratic nature of maintenance workload
B. List the configuration differences between different aircraft
C. Minimize maintenance delays
D. A & B
E. A & C - ANS✔✔ A & C
Chose the answer which correctly lists the order in which a maintenance group will address a
problem.
Determine if the failure is 1. Safety related 2. Hidden or obvious 3. Has operational impact
And determine 4. Which task to be applied 5. The maintenance interval
A. 1, 2, 3, 4, 5
B. 2, 1, 3, 4, 5
C. 4, 5, 1, 2, 3
D. 1, 2, 3, 5, 4 - ANS✔✔ 2, 1, 3, 4, 5
True or False: The MSG-3 process was designed as a fundamentally different and unique
maintenance process from MSG-2 - ANS✔✔ False
True or False: An aircraft operating in a humid environment may be subject to a maintenance
task more often than the MRB report indicates compared to operation in a dry climate. -
ANS✔✔ True
