Dispatcher Distance Learning Course-Week 1


This is View Only - You must be an enrolled student with AGS to take this exam!!!






1. The 4 forces are:
rudder, elevator, flaps, ailerons.
lift, weight, thrust, and drag.
light, darkness, good, and evil.


2. The B737 and B727 are examples of an aircraft:
category.
class.
type.


3. Although a given airfoil always stalls at the same angle of attack, a stall can occur:
at any airspeed (and in any flight attitude).
whenever the nose of the aircraft is significantly above the horizon.
only when the airspeed drops below the published stalling speed.


4. As the gross weight of an airplane is increased, the stalling speed generally:
remains the same.
decreases.
increases.


5. The majority of weather in the United States is:
generally moving from east to west.
caused by arctic fronts.
the result of interaction between polar air masses and temperate or subtropical climates.


6. Relative wind is independent of which way the airplane's __________is pointed.
fuselage
nose
both are correct


7. The symbol V1 represents:
the lowest speed registered by an airspeed indicator.
takeoff safety speed.
takeoff decision speed.


8. "Multi-engine land" is an example of an aircraft:
category.
class.
type.


9. The primary cause of changes in the earth's weather is:
the flow of air from pole to equator.
uneven heating of the earth's surface by the sun.
coriolis force.


10. Standard atmosphere includes which of the following values
59 degrees F; 29.92 hg; 14.7 lbs per square inch.
15 degrees C and 1013.2 mb.
Both a and b.


11. A temperature lapse rate of a parcel of air is warmer than the standard dry adiabatic lapse rate.
This air is absolutely stable.
This air is absolutely unstable.
This air is stable if dry; unstable if moist.


12. Air descends and flows outwards in a high pressure system.
True.
False.


13. Land absorbs and radiates heat much faster than water
True.
False.


14. Which stage of a thunderstorm is characterized by prevailing downdrafts.
Microburst.
Dissipating.
Mature.


15. Moist air flowing over colder flat ground will form advection fog.
True.
False.


16. The temperature decreases as altitude increases. This is:
always true.
true in the troposphere.
true in a temperature inversion.


17. _________are usually associated with well-developed surface lows and frontal systems beneath deep upper troughs or lows.
Jet streams.
Temperatures.
Katabatic winds.


18. An aircraft operating under VFR in Class B airspace is required to
remain 1000' over, 500' under, and 1000' horizontally from clouds.
remain clear of clouds.
maintain flight visibility of 3 nm.


19. What 4 things happen when you fly through a front.
Pressure, temperature, winds and dewpoint change.
Pressure drops, temperature drops, wind is steady, and it starts precipitating.
You get wet; experience turbulence; your ears pop, and temperature rises.


20. During a coordinated, continuous turn, in level flight.
a portion of the centrifugal force is countered by a horizontal component of lift.
the aircraft will lose altitude unless power is added.
rudder opposite to the direction of the turn must be applied because of answers a and b.
