1.
An aircraft dispatcher is jointly responsible with the pilot in command for the
operational control of a Part 121 flight. Which action is most consistent with this
responsibility?
A. The dispatcher may delegate all operational decisions to ATC.
B. The dispatcher is responsible only for weather information before departure.
C. The dispatcher and pilot in command share responsibility for the safe conduct
of the flight.
D. The dispatcher becomes responsible only after the aircraft enters controlled
airspace.
Answer: C
Operational control in Part 121 involves joint dispatcher-pilot responsibility for the
safety of the flight.
2.
A dispatcher is preparing a flight and discovers that significant thunderstorms are
forecast along the planned route. The most appropriate initial action is to:
A. Ignore the forecast if the destination weather is VFR.
B. Evaluate the thunderstorms, available deviations, fuel requirements, and
operational consequences before releasing the flight.
C. Release the flight and allow the captain to decide after departure.
D. Cancel the flight automatically.
Answer: B
The dispatcher must analyze the complete operational situation and ensure that
the proposed flight can be conducted safely.
,3.
Which weather condition is most strongly associated with severe turbulence,
icing, hail, lightning, and strong vertical currents?
A. Stratiform cloud below an inversion
B. Radiation fog
C. Thunderstorms
D. High cirrus
Answer: C
Thunderstorms can contain multiple severe aviation hazards simultaneously,
including severe turbulence, hail, icing, lightning, and strong updrafts and
downdrafts.
4.
A METAR reports: KDEN 241853Z 31018G28KT 1/2SM R35L/2400FT TSRA
BKN008CB. Which condition presents the greatest immediate operational
concern?
A. Wind direction
B. Visibility only
C. Thunderstorm with cumulonimbus and very low ceiling
D. Runway identifier
Answer: C
TSRA indicates thunderstorms with rain, CB indicates cumulonimbus, and BKN008
indicates a broken ceiling at 800 feet.
5.
A TAF contains TEMPO 2420/2424 2SM TSRA BKN020CB. What does TEMPO
indicate?
A. The condition will occur continuously throughout the period.
B. The condition is permanently replacing the prevailing forecast.
C. Temporary fluctuations in weather conditions are expected during the stated
,period.
D. The forecast has been canceled.
Answer: C
TEMPO identifies temporary conditions expected to occur during the specified
validity period.
6.
Which type of icing is generally considered especially hazardous because it can
form a rough, irregular accumulation that is difficult to shed?
A. Frost
B. Rime
C. Clear icing
D. Dry snow
Answer: C
Clear ice can form a hard, dense accumulation and may spread beyond protected
areas of the aircraft.
7.
An aircraft is flying toward a developing cold front. Which weather sequence is
generally most characteristic of a strong cold front?
A. Gradual widespread stratiform precipitation followed by steady warming
B. Rapidly changing weather, showers or thunderstorms, gusty winds, and a
temperature decrease
C. Persistent calm winds and clear skies
D. Increasing temperature with decreasing pressure followed by no wind shift
Answer: B
Cold fronts can produce abrupt wind shifts, precipitation, turbulence,
thunderstorms, and a noticeable temperature decrease.
8.
, Which pressure pattern is generally associated with descending air and more
stable weather?
A. Low pressure
B. Trough
C. High pressure
D. Frontal wave
Answer: C
High-pressure systems are generally associated with sinking air, which tends to
suppress cloud development.
9.
What is the primary operational significance of a SIGMET?
A. It reports routine surface weather.
B. It provides airport parking information.
C. It advises of significant en route weather phenomena that may affect the
safety of all aircraft.
D. It reports only visibility below minimums.
Answer: C
SIGMETs concern significant weather hazards that can affect aircraft operations.
10.
An AIRMET is primarily intended to provide information concerning:
A. Only thunderstorms containing tornadoes
B. Weather phenomena potentially hazardous to all aircraft, particularly those
operating under specified conditions
C. Airport construction
D. Aircraft maintenance discrepancies
Answer: B
