EAWS - Enlisted Aviation Warfare Specialist Aircraft Fundamentals and Systems Questions and Answers

Question 1

An aircraft's landing gear fails to retract after takeoff.
The hydraulic pressure gauge indicates a rapid drop to zero, and a visual inspection from the cabin reveals fluid streaming from the right main gear wheel well.
Which of the following components has most likely failed?

Accepted Answer

An actuating cylinder seal

Answer

The main system reservoir

Answer

A pressure relief valve

Answer

An engine-driven pump

Question 2

Most modern naval aircraft fuselages use a semi-monocoque construction. What is the primary characteristic of this design?

Accepted Answer

The skin is reinforced by a substructure of formers and stringers that share the structural load.

Answer

The external skin is the sole load-bearing component.

Answer

A framework of steel tubes provides the primary structural strength.

Answer

All structural loads are carried by a single, central keel beam.

Question 3

Within a turbofan engine, what is the primary function of the compressor section?

Accepted Answer

To squeeze incoming air and increase its pressure and temperature before combustion.

Answer

To ignite the fuel-air mixture.

Answer

To drive the fan and other engine accessories.

Answer

To decrease the velocity of the exhaust gases to reduce noise.

Question 4

Which of the following correctly describes the typical roles of AC and DC power on a naval aircraft?

Accepted Answer

AC power is used for high-power systems like motors and heating, while DC power is used for solid-state electronics and as a backup source from batteries.

Answer

AC is used exclusively for avionics, while DC powers all motors and pumps.

Answer

DC power is the primary power source, converted to AC only for specific high-power systems.

Answer

AC and DC power are used interchangeably, with the aircraft's systems able to accept either type of current.

Question 5

Movement of an aircraft around its longitudinal axis, also known as roll, is controlled by which primary flight control surface?

Accepted Answer

Ailerons

Answer

Elevators

Answer

Rudder

Answer

Flaps

Question 6

A pilot is conducting a pre-flight check and cycles the flight controls. When they push the control stick forward, a specific control surface moves. What is the primary purpose of this action during flight?

Accepted Answer

To decrease the aircraft's pitch and cause the nose to lower.

Answer

To yaw the aircraft's nose to the right.

Answer

To increase the rate of climb.

Answer

To increase wing lift for takeoff.
