(Refer to figure 18) What weather phenomenon is causing IFR conditions in central Oklahoma?

Select the correct answer(s).

(0/0)

Explanation

The shaded area indicates IFR. In this case, the filled station model in central Oklahoma indicates overcast sky and the "3" below the model indicates 300-foot ceiling. The "2-1/2" to the left of the model indicates IFR visibility of 2-1/2 statute miles.

(Refer to figure 18) According to the Weather Depiction Chart, the weather for a flight from southern Michigan to north Indiana is ceilings

Select the correct answer(s).

(0/0)

Explanation

There are no shaded or contoured areas along this route. This indicates VFR areas with a ceiling greater than 3,000 feet and a visibility greater than 5 miles.

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

Select the correct answer(s).

(0/0)

Explanation

Radar weather reports show areas of precipitation; type, such as rain showers; intensity, such as light or heavy; and azimuth of movement. Intensity trend is no longer coded on the Radar Weather Report.

What information is provided by the Radar Summary Chart that is not shown on other weather charts?

Select the correct answer(s).

(0/0)

Explanation

Individual thunderstorm cells as well as lines of thunderstorms are depicted on radar summary charts. Since the radar returns are reflected off precipitation, not clouds, they do not show ceilings or types of clouds.

(Refer to figure 19) (Area B) What is the top for precipitation of the radar return?

Select the correct answer(s).

(0/0)

Explanation

240 indicates the highest precipitation top in the area in hundreds of feet above mean sea level, which in this case is 24,000 feet MSL.

(Refer to figure 20) How are Significant Weather Prognostic Charts best used by a pilot?

Select the correct answer(s).

(0/0)

Explanation

In addition to outlining areas of instrument flight rule (IFR) and marginal visual flight rule (MVFR) weather, these charts include freezing levels and areas of turbulence. Since the significant weather panels are valid from the surface up to 24,000 fee

none

(Refer to figure 20) Interpret the weather symbol depicted in Utah on the 12-hour Significant Weather Prognostic Chart

Select the correct answer(s).

(0/0)

Explanation

On the upper left panel, the symbol indicates moderate turbulence. The notation 180/ means the turbulence is from the surface up to 18,000 feet.

(Refer to figure 20) What weather is forecast for the Florida area just ahead of the stationary front during the first 12 hours?

Select the correct answer(s).

(0/0)

Explanation

The upper left panel indicates ceiling 1,000-3,000 feet and/or a visibility of 3-5 miles. This is marginal VFR (MVFR). The dot symbols in the shaded area within the lower left panel indicates continuous rain.

(Refer to figure 20) At what altitude is the freezing level over the middle of Florida on the 12-hour Significant Weather Prognostic Chart?

Select the correct answer(s).

(0/0)

Explanation

The upper left panel contains a dashed green line marked with the number 120, which crosses central Florida. This represents the height of the 12,000-ft. freezing level.

Individual forecasts for specific routes of flight can be obtained from which weather source?

Select the correct answer(s).

(0/0)

Explanation

The information in a transcribed weather broadcast (TWEB) varies, but generally it contains route-oriented data.

Transcribed Weather Broadcasts (TWEBs) may be monitored by tuning the appropriate radio receiver to certain

Select the correct answer(s).

(0/0)

Explanation

TWEB's are broadcast over certain VOR and NOB frequencies. Airport advisory frequencies are used by an FSS at uncontrolled airports to provide general airport information to pilots. Automatic terminal information service (ATIS) frequencies are used to bro
