✔✔it would increase the load factor


The additional load factor that results from vertical gusts is _____ proportional to the wing loading. -

✔✔inversely


Which load factor can be defined as the highest load factor that can be expected in normal operations,

A compensating downward current of air results from rising thermals, but the downdrafts are over a

broad area and therefore weaker than the updrafts. - ✔✔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 -

✔✔Neutral


Which type of surface feature would heat-up the most and produce the strongest convective thermals? -

✔✔sandy or rocky wastelands


What atmospheric phenomena prevents thermals from rising higher and is the top of the convective (or

mixed) layer? - ✔✔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? - ✔✔super adiabatic layer


One method used to describe thermals is the column or plume model. - ✔✔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. -

✔✔conditional


What are the requirements for Kelvin Helmholtz waves? - ✔✔strong stability and strong shear


How does the boundary layer change with increasing wind speed? - ✔✔the depth of the boundary layer

increases


A wave is often the precursor to shear turbulence. - ✔✔true


The magnitude of wind shear (usually measured in knots per distance) is called - ✔✔shear gradient


Moderate or greater turbulence can be expected if the surface winds exceed ___ knots over a flat surface. -

✔✔30
