answers rated A+
A conceptual model for turbulence flow categorizes turbulence as either -
correct answer ✔waves or eddies
Airplanes that have a greater velocity have greater momentum. - correct
answer ✔true
The critical size range (or diameter) of eddies to be felt by aircraft as
turbulence is between - correct answer ✔50 and 1500 ft
"The time rate of change of momentum of a body is equal to the force on the
body" is a statement of - correct answer ✔Newtons Second Law of Motion
"A body remains at rest or in a state of uniform motion unless it is acted on by
a force" is a statement of - correct answer ✔Newtons First Law of Motion
How would an upward directed force (such as a turbulence gust) affect the
load factor of an airplane? - correct answer ✔it would increase the load
factor
The additional load factor that results from vertical gusts is _____ proportional
to the wing loading. - correct answer ✔inversely
Which load factor can be defined as the highest load factor that can be
expected in normal operations, and aircraft are designed to withstand these
load factors without structural damage? - correct answer ✔flight (or limit)
load factor
, Which factor does not determine the transition from laminar to turbulent flow in
the atmosphere? - correct answer ✔relative humidity
A compensating downward current of air results from rising thermals, but the
downdrafts are over a broad area and therefore weaker than the updrafts. -
correct answer ✔true
____________ stability is the state of a column of air in the atmosphere in
which an ascending (or descending) air parcel always has the same
temperature (density) as the surrounding environmental air - correct answer
✔Neutral
Which type of surface feature would heat-up the most and produce the
strongest convective thermals? - correct answer ✔sandy or rocky
wastelands
What atmospheric phenomena prevents thermals from rising higher and is the
top of the convective (or mixed) layer? - correct answer ✔capping inversion
What is the name given to the shallow, absolutely unstable layer of air in
contact with the Earth's surface which produces bubbles of vertically rising
air? - correct answer ✔super adiabatic layer
One method used to describe thermals is the column or plume model. -
correct answer ✔true
____________ stability is the state of a column of unsaturated air in the
atmosphere when its lapse rate of temperature is less than the dry adiabatic
lapse rate, but greater than the moist adiabatic lapse rate. - correct answer
✔conditional
