AVIA 400 Quiz 3


LU AVIA 400 Quiz 3

Question 1- Type III (incapacitating) SD occurs when you are aware of
your disorientation and can properly take positive control of your
aircraft.
➢ False

Question 2- Airframe noise is usually at slower speeds and
higher at the speeds involved in cruise and descent.
➢ Lower

Question 3- The semicircular canals react primarily to steady
velocities, not accelerations.
➢ True

Question 4- Acceleration is the rate of change of velocity.
➢ True

Question 5- Gray out and blackout are caused by hypoxia.
➢ Stagnant

Question 6- A comparison of speech intensity to noise intensity is called the
➢ Signal-to-noise ratio (SNR)

Question 7- - Sensory illusions involving primarily the semicircular canals
are often referred to as illusions.
➢ Somatogyral illusions

Question 8- Sound wave energy is substantially reduced when passing from a
gas (air in outer ear) to a liquid (fluid in inner ear); but the unique
mechanical arrangement of the middle ear makes up for this limitation by
amplifying the sound energy by as much as 25 dB.
➢ True

Question 9- A study conducted by the University of Illinois in the 1950s found
that pilots with insufficient instrument flying ability lose control of their
airplane in an average of only once they lose outside visual references.
➢ average of 178 seconds

Question 10- Airframe noise is partly a function of indicated airspeed
(dynamic air pressure) expressed as 1/2ρV2, where ρ (rho) is the density of
the air and V is the true airspeed. Therefore, the slower the airspeed and
higher the altitude (lower air density), the greater the aerodynamic noise
created around the aircraft’s fuselage.
➢ False
