Embry- Riddle Final Exam Actual Questions and Answers
with complete solution
On what date did the Wright Brothers made the first successful controlled,
manned, heavier than air and powered flight?
December 17, 1903
What is load factor?
The ratio of total load supported by the aircraft's wings (lift) to the actual weight of the
aircraft.
Who is considered the "Father of Airline Deregulation"?
Fred Kahn
Signed into law in October 1978, the Airline Deregulation Act introduced
unrestricted fare and route competition. The airline industry was re-regulated in
2001.
removing U.S. Federal Government control over such things as fares, routes and
market entry of new airlines, introducing a free market in the commercial airline industry
ailerons
a hinged surface in the trailing edge of an airplane wing, used to control roll
flaps
located on the inside trailing edges of the wings. They can be extended to provide
greater wing area slower speeds. This provides more lift and drag and allows an
airplane to land, take off, or fly at slower speeds
horizontal stabilizer
Located in the rear of the airplane, is designed to provide continuous longitudinal (from
front to rear) stability. It prevents uncontrolled up and down movements of the nose
(pitching).
vertical stabilizer
provides directional (left or right) stability. It prevents uncontrolled left or right
movements of the nose. (yawing)
rudder
located on the vertical stabilizer and controls yawing motion.
elevator trim tabs
-rees the pilot from exerting constant force on the pitch controls. mall, folded extensions
found on the ailerons, rudders and elevator of airplanes. They are used so that pilots
can control the airplane's trim to achieve a smoother flight experience
elevator
a moveable part on the rear of the horizontal stabilizer. It is used to move the airplane
about the lateral axis. It provides the input of pitch and helps control altitude.
According to the Bernoulli Principle, how does an airfoil generate lift?
As the velocity of a fluid increases, the pressure in the fluid decreases. Faster moving
air on the top surface of a wing develops a lower pressure than the slower moving air on
the bottom surface of the wing, creating lift.
Why is it critical for aviators to know the value of density altitude?
Less dense air causes a reduction in lift generated by the wings and would reduce
power output, which reduces the effectiveness of propellers.
