AVIATION AND MARITIME CONCEPTS ACTUAL EXAM 2025|
QUESTIONS AND ANSWERS
1. A reduction gear is fitted:
Between the camshaft and the propeller.
Between the pushrods and the valves.
Between the crankshaft and propeller.
Between the connecting rod and the crankshaft.
2. Which type of vessel must a power-driven vessel give way to according to
maritime navigation rules?
Any vessel not under command
Any vessel under command
Any vessel engaged in recreational boating
Any vessel with a larger size
3. If a sailor needs to determine the depth of water in a harbor and finds it to
be 30 fathoms, how many feet deep is the water?
90 feet
150 feet
180 feet
120 feet
4. Who was the first american to orbit the earth, and what was his spacecraft
called?
John H. Glenn in the Friendship-7
John H. Glenn in the Mercury Atlas-6
Niel Armstrong in the Friendship-7
, Adam Mullens in the Columbia
5. If a maritime vessel is operating in rough seas and a crew member falls
overboard, how might the presence of lifelines have altered the outcome
of the situation?
The lifelines would have prevented the crew member from falling
overboard entirely.
The lifelines would have provided a means for the crew member to
pull themselves back on board.
The lifelines would have helped other crew members to secure the
individual before they fell.
The lifelines would have created a safer environment, reducing
the likelihood of falls in the first place.
6. Explain why dihedral effect is important for an aircraft's stability.
It helps maintain altitude during flight.
It enhances the aircraft's ability to recover from a roll.
It reduces drag during high-speed maneuvers.
It increases the lift generated by the wings.
7. _______ is the actual height above mean sea level (MSL)
true altitude
pressure altitiude
density altitude
indicated altitude
8. Explain the significance of the yellow arc on an airspeed indicator and how
it affects pilot decision-making.
It indicates the maximum speed a pilot can fly.
, It warns pilots to avoid flying at speeds within this range unless in
smooth air.
It shows the minimum speed required for takeoff.
It represents the normal operating speed for the aircraft.
9. If an aircraft has a maximum gross weight of 50,000 pounds and currently
weighs 45,000 pounds with all passengers and cargo loaded, how much
additional cargo can be safely added without exceeding the maximum
gross weight?
1,000 pounds
5,000 pounds
10,000 pounds
15,000 pounds
10. Explain the impact of Charles Lindbergh's solo flight across the Atlantic in
1927 on the aviation industry.
It led to the development of commercial air travel.
It resulted in the establishment of the Federal Aviation
Administration.
It marked the end of military aviation advancements.
It had no significant impact on aviation.
11. Explain the significance of knowing an aircraft's gross weight in aviation
operations.
It determines the aircraft's maximum speed.
It is essential for calculating fuel efficiency and safety margins.
It affects the aircraft's color and design.
It is irrelevant to flight planning.
, 12. Explain the significance of each cycle in the operation of an internal
combustion aircraft engine.
They represent the stages of fuel consumption
They indicate the phases of engine cooling
They describe the process of converting fuel into mechanical
energy
They outline the maintenance schedule for the engine
13. Explain how an altitude indicator contributes to flight safety and
navigation.
It helps pilots maintain a constant speed during flight.
It allows pilots to determine their altitude relative to sea level,
which is crucial for avoiding obstacles and ensuring safe
landings.
It provides information on the aircraft's fuel consumption.
It assists in calculating the distance to the destination.
14. Nearing the end of her 1937 world flight, American aviatrix Amelia Earhart
and her navigator Fred Noonan disappeared over the Pacific Ocean as
they were flying to this destination:
Lae, New Guinea
Majuro, Marshall Islands
Howland Island
Honolulu, Hawaii
15. If a pilot is flying in an area with significant magnetic interference, which
navigation instrument would be most reliable for determining the aircraft's
heading, and why?
Magnetic Compass, because it directly uses magnetic pull.
