Aviation Weather Information Quiz

Geostationary weather satellites orbit the Earth at a high altitude of approximately 36,000 km over the Equator, monitoring the same area on Earth continuously. Examples include GOES (Geostationary Operational Environmental Satellite) by the USA, Elektro-L by Russia, MTSAT by Japan, Fengyun by China, and Meteosat by Europe.

Polar-orbiting weather satellites orbit at a low altitude of approximately 800 km and the same area on Earth passes under them twice per day. An example is the Fengyun series launched by China.

SIGWX charts are issued by World Area Forecast Centres (WAFC) every 6 hours, presenting the most important meteorological phenomena relevant to air traffic transport.

The official (closed) and non-sensitive methods of collecting weather information mentioned in the text are weather radar, weather balloon, weather satellite, and human observer.

Geostationary weather satellites orbit at a high altitude of approximately 36,000 km.

Geostationary weather satellites orbit at the same speed as Earth's rotation over the Equator.

Polar-orbiting weather satellites orbit at a low altitude of approximately 800 km.

The same area on Earth passes under polar-orbiting weather satellites twice per day.

An example of a geostationary weather satellite launched by Japan is MTSAT (Multifunctional Transport Satellite).

The Geostationary Operational Environmental Satellite (GOES) was launched by the USA.

Low-level charts cover altitudes below 10,000 ft, while medium/high-level charts cover altitudes from FL100 to FL450.

The symbols on aviation charts indicate weather conditions such as moderate/severe icing and turbulence.

A convergence zone is an isolated cumulonimbus cloud with potential thunderstorms, icing, and turbulence, with its top at 41,000 ft.

SIGWX charts provide information on weather phenomena at different flight levels.

A Surface Weather Map displays wind barbs, sky cover, types of weather, and pressure trend.

Station model interpretation includes temperature, sea level pressure, visibility, and wind direction.

The validity period for volcanic ash and tropical cyclone advisories provided by SIGMET is up to 6 hours.

AIRMET covers weather less severe than SIGMET, with categories like mountain obscuration, turbulence, and icing.

The example 'AIRMET SIERRA UPDT 4' indicates IFR and mountain obscuration conditions.

Graphical AIRMET (G-AIRMET) provides a graphical representation of AIRMET information.

Pilot Reports (PIREPs) are weather reports filed by pilots during flight to share observed conditions.

Geostationary satellites orbit over the Equator at high altitude and monitor the same area on Earth continuously, while polar-orbiting satellites orbit at low altitude and pass over the same area on Earth twice per day.

Approximately 36,000 km.

Approximately 800 km.
