9900 and less than 5 knots

SIGMETs are issued as a warning lf weather conditions hazardous to which aircraft?

All aircraft

To update a previous weather briefing, a pilot should request

An abbreviated 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 the information requested is six or more hours before the proposed departure time is

An outlook briefing

(Refer to figure 15). The only cloud type forecast in the TAF reports is

Cumulonimbus

How are low-level significant weather (sigwx) prognostic charts best used by a pilot?

For determining areas to avoid (Freezing levels and turbulence).

(Refer to figure 12,) Which of the reporting stations have VFR Weather?

KINK, KBOI, and KLAX

(Refer to figure 14). The intensity and type of icing reported by a pilot is

Light to moderate rime

Which in-flight advisory would contain information on severe icing not associated with thunderstorms?

SIGMET

Sky 700 feet overcast, visibility 1-1/2 SM, rain

What considerations apply when using a cockpit display of radar data obtained from FIS-B?

The radar echoes that are depicted on the cockpit display can sometimes be more than 20 minutes old.

What information is contained in a convective SIGMET?

Tornadoes, embedded thunderstorms, and hail 3/4 inch or greater in diameter.

What values are used for Winds Aloft Forecasts?

True direction and knots.

(Refer to figure 15). What is the forecast wind for KMEM form 1600Z until the end of the forecast?

To get a complete weather briefing for the planned flight, 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?

a standard briefing

AIRMET's are advisories of significant weather phenomena but of lower intensities than SIGMET's and are intended for dissemination to

all pilots

When requesting weather information for the following morning, a pilot should request

an outlook briefing

Low-level significant weather (SIGWX) charts provide depictions of forecast

aviation weather hazards such as MVFR and IFR conditions, turbulence, and freezing.

(Refer to figure 15). During the time period from 0600Z to 0800Z, what is the visibility is forecast for KOCK?

greater than six statue miles

You plan to phone a weather briefing facility for preflight weather information. You should

identify yourself as a pilot.

To determine the freezing level and areas of probable icing aloft, the pilot should refer to the

inflight aviation weather advisories

(Refer to figure 14). The intensity of the turbulence reported at a specific altitude is

light from 5500 feet to 7200 feet

Radar weather reports are of special interest to pilots because they indicate...

location of precipitation along with the type, intensity, and cell movement of precipitation.

For aviation purposes, ceiling is defined as the height above the earth's surface of the

lowest broken layer or overcast layer or vertical visibility into an obscuration.

You planned a route and obtained preliminary weather information to determine the feasibility of your flight. On the morning of your flight, an FAA-approved briefing consists of

obtaining a standard briefing at 1800wxbreif.com.

(Refer to figure 15).In the TAF from KOKC, the clear sky becomes

overcast at 2000 feet during the forecast period between 2200Z and 2400Z

(Refer to figure 12). The remarks section for KMDW has RAB35 listed. This entry means

rain beginning at 1835Z

(Refer to figure 15). In the TAF for KMEM, what does "SHRA" stand for?

rain showers are expected

Short range surface prog charts provide depictions of forecast

surface pressure systems, fronts, and precipitation.

When telephoning a weather briefing facility for preflight weather information, pilots should state

the airplane identification or the pilot's name

What is indicated when a convective SIGMET forecasts thunderstorms.

thunderstorms obscured by massive cloud layers.

When speaking to a flight service weather briefer, you should state

whether the flight is VFR or IFR
