Question 1

Eddy currents

Answer 1

. Current induced in a metal cup or disc when

it is crossed by lines of flux from a moving magnet.

Question 2

Eddy current damping

Answer 2

The decreased amplitude of
oscillations by the interaction of magnetic fields. In the case
of a vertical card magnetic compass, flux from the oscillating
permanent magnet produces eddy currents in a damping disk
or cup. The magnetic flux produced by the eddy currents
opposes the flux from the permanent magnet and decreases
the oscillations.

Question 3

Electronic Flight Display (EFD)

Answer 3

For the purpose of
standardization, any flight instrument display that uses LCD
or other image-producing system (cathode ray tube (CRT),
etc.)

Question 4

Elevator

Answer 4

The horizontal, movable primary control surface
in the tail section, or empennage, of an airplane. The
elevator is hinged to the trailing edge of the fixed horizontal
stabilizer.

Question 5

Elevator illusion

Answer 5

The sensation of being in a climb or
descent, caused by the kind of abrupt vertical accelerations
that result from up- or downdrafts.

Question 6

Emergency

Answer 6

A distress or urgent condition

Question 7

Empennage

Answer 7

The section of the airplane that consists of the
vertical stabilizer, the horizontal stabilizer, and the associated
control surfaces.

Question 8

Emphasis error

Answer 8

The result of giving too much attention
to a particular instrument during the cross-check, instead of
relying on a combination of instruments necessary for attitude
and performance information.

Question 9

Empty-field myopia

Answer 9

Induced nearsightedness that is
associated with flying at night, in instrument meteorological
conditions and/or reduced visibility. With nothing to focus
on, the eyes automatically focus on a point just slightly ahead
of the airplane.

Question 10

EM Wave

Answer 10

Electromagnetic wave

Question 11

Encoding altimeter

Answer 11

A special type of pressure altimeter
used to send a signal to the air traffic controller on the ground,
showing the pressure altitude the aircraft is flying.

Question 12

Engine Pressure Ratio (EPR)

Answer 12

The ratio of turbine discharge
pressure divided by compressor inlet pressure, which is used
as an indication of the amount of thrust being developed by
a turbine engine.

Question 13

En route facilities ring

Answer 13

Depicted in the plan view of IAP
charts, a circle which designates NAVAIDs, fixes, and
intersections that are part of the en route low altitude airway
structure.

Question 14

En Route Flight Advisory Service (EFAS)

Answer 14

An en route weather-only AFSS service

Question 15

En route high-altitude charts

Answer 15

Aeronautical charts for en

route instrument navigation at or above 18,000 feet MSL.

Question 16

En route low-altitude charts

Answer 16

Aeronautical charts for en

route IFR navigation below 18,000 feet MSL

Question 17

Equilibrium

Answer 17

A condition that exists within a body when the
sum of the moments of all of the forces acting on the body
is equal to zero. In aerodynamics, equilibrium is when all
opposing forces acting on an aircraft are balanced (steady,
unaccelerated flight conditions).

Question 18

Equivalent airspeed

Answer 18

Airspeed equivalent to CAS in
standard atmosphere at sea level. As the airspeed and pressure
altitude increase, the CAS becomes higher than it should be,
and a correction for compression must be subtracted from
the CAS.

Question 19

Evaporation

Answer 19

The transformation of a liquid to a gaseous

state, such as the change of water to water vapor.

Question 20

Exhaust Gas Temperature (EGT)

Answer 20

The temperature of the
exhaust gases as they leave the cylinders of a reciprocating
engine or the turbine section of a turbine engine.

Question 21

Expect-Further-Clearance (EFC)

Answer 21

The time a pilot can

expect to receive clearance beyond a clearance limit.

Question 22

Explosive decompression

Answer 22

A change in cabin pressure faster

than the lungs can decompress. Lung damage is possible.
