Aviation Weather Services

To get a complete weather overview for the planned flight, the remote pilot-in-command should obtain

• An outlook briefing.

• An abbreviated briefing.

• A standard briefing.

Which statement is true concerning ASOS/AWOS weather reporting system?

• Each AWOS station is part of a nationwide network of weather reporting stations.

  Explanation: While AWOS stations are widespread, they are not necessarily part of a nationwide network in the same way as ASOS.

• ASOS locations perform weather observing functions necessary to generate METAR reports.

  Explanation: ASOS (Automated Surface Observing Systems) are designed to provide the necessary observations for METAR reports, which are essential for aviation weather information.

• Both ASOS and AWOS have the capability of reporting density altitude, as long as it exceeds the airport elevation by more than 1,000 feet.

  Explanation: Neither ASOS nor AWOS specifically report density altitude in this manner; they provide data that can be used to calculate it.

(Refer to Figure 12.) The wind direction and velocity at KJFK is from

• 180° true at 4 knots.

• 180° magnetic at 4 knots.

• 040° true at 18 knots.

(Refer to Figure 12.) What are the current conditions for Chicago Midway Airport (KMDW)?

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

• Sky 7,000 feet overcast, visibility 1-1/2 SM, heavy rain.

• Sky 700 feet overcast, visibility 11, occasionally 2 SM, with rain.

(Refer to Figure 15.) Between 1000z and 1200z the visibility at KMEM is forecast to be

• 1/2 statute mile.

• 3 statute miles.

• 6 statute miles.

What will a convective SIGMET be issued for?

• Squall line thunderstorm. A convective SIGMET is issued for severe convective activity, such as squall line thunderstorms, which pose a significant hazard to aviation.

• Visibility less than 3 miles. This condition is not typically associated with convective SIGMETs, which focus on severe convective weather phenomena.

• Surface winds greater than 40 knots. While strong surface winds can be hazardous, convective SIGMETs specifically address severe convective weather like thunderstorms.

What does a METAR report indicate?

• A) Airfield weather conditions

• B) Flight schedule

• C) Passenger list

• D) Fuel consumption

A SPECI message is identical to a METAR but is established ______ instead of regularly.

Explanation: A SPECI (Special Weather Report) is issued when there are significant changes in weather conditions that need to be reported immediately, rather than waiting for the next scheduled METAR report. This is why it is established punctually, as needed, rather than at regular intervals.

• A) Punctually

• B) Hourly

• C) Daily

• D) Weekly

Fill in the blank: The code 'FEW' in cloud description indicates a sky cover of ___ to 2/8.

Explanation: In meteorological terms, 'FEW' is used to describe a sky condition where clouds cover 1/8 to 2/8 of the sky. It indicates a small amount of cloud cover, which is less than 'SCT' (scattered) and more than 'SKC' (sky clear).

• 1/8

• 3/8

• 5/8

• 7/8

What does the abbreviation 'BECMG' stand for in METAR messages?

Answer Explanation: In METAR messages, 'BECMG' is used to indicate a change in weather conditions that is expected to occur gradually over a period of time. It stands for 'Becoming', which means that the weather is transitioning to a new state.

• Becoming

• Beginning

• Between

• Before
