Aviation Weather Services Flashcards
To get a compete weather briefing for the planned fight, the pilot should request
a standard briefing
Which type weather briefing should a pilot request, when departing within the hour, if no preliminary weather information has been received?
Standard briefing
Which type of weather briefing should a pilot request to supplement mass disseminated data?
An abbreviated briefing
A weather briefing that is provided when teh information requested is 6 or more hours in advnce of the proposed departure time is
an outlook briefing
What should pilots state initially when telephoning a weather briefing facility for preflight weather information
Identify themselves a pilots
What should pilots state initially when telephoning a weater briefing facility for preflight weather information?
The intended route of flight and destination
When telephoning a weather briefing facility for preflight weather information pilots should state
the aircraft identification or the pilots name
When tekephoning a weather briefing facility for preflight weather information, pilots should state
whether they intend to fly VFR only
To update a previous weather briefing, a pilot should request
an abbreviated briefing
When requesting weather information for the following morning, a pilot should request
an outlook briefing
For aviation purposes, ceiling is defined as teh height above the Earth’s surface fo the
lowest broken or overcast layer or vertical visibility into an obscuration
To best determine general forcast weather conditions over several states, the pilot shoudl refer to
Aviation Area Forcasts
To determine the freezing level and areas of probable icing aloft, the pilot should refer tothe
Inflight Aviation Weather Advisories
The section of the Area Forcast entitled VFR CLDS/WX contains a general description of
clouds and weather which cover an area greater than 3,000 square miles and is significant to VFR flight operations
From which primary source should information be obtained regarding expected weather at the estimated time of arrival if your destination has no Terminal Forcast?
Area Forcast
Of what value is Weather Depiction Chart to the pilot?
For determining general weather conditions on which to base flight planning
What does the heavy dashed line that forms a large rectangular box on a Radar Summary Chart refer to?
Severe weather watch area
What information is provided by the Radar Summary Chart that is not shown on other weather charts?
Lines and cells of hazerdous thunderstorms
Radar weather reports are of special interet to pilots because they include
location of precipitation along with tupe intensity and cell movement of precipitation
How should contact be established with an En Route Fligth Advisor Service (EFAS) statin, and what service would be expected?
Call FLight Watch on 122.0 for information reagrding actual weather and thunderstorm activity along proposed route
What service shoudl a pilot normally expect from an En Route Flight Advisory Servide (EFAS) station?
Actual weather information and thunderstorm activity along the route
Below Fl 180, en route weaterh advisories should be obtained from an FSS on
122.0 MHz
When the term “lighy and variable” is used in referecne to Winds Aloft Forecast, teh coded group and windspeed is
9900 and less than 5 knots
What values are used for Winds Aloft Forecasts?
True direction and knots
How are Significant Weather Prognostic Charts best used by a pilot?
For determining areas to avoid (freezing levels and turbulence)
SIGMETs are issued as a waring of weather conditins hazardous to which aircraft?
All aircraft
AIRMETs are advisories of sinificant weather phenomena but of lower intensities than SIGMETs and are intended for dissemination to
all pilots
Which in flight advisory would contain information on sever icing not associated with thunderstorms
SIGMET
What information is contained in a CONVECTIVE SIGMET?
Tornadoes, embedded thunderstorms, and hail 3/4 inch or greater in diameter
What is indicated when a current CONVECTIVE SIGMET forcasts thunderstorms?
Thunderstorms obsucred by massive cloud layers
