Popular science knowledge| Necess↑"ity of using meteorological s≈↑ βensor observation equipment in ↔₹ civil aviation field
With the continuous $≠©♣progress of society and sγ•γcience and technology,♣♣& China's aviation in∞'dustry has developed rapidly. Flyλ®ing has become one of the÷↓↔ preferred transporta ∞tion modes for people to travel.®" China has gradually trε<¶$ansformed from a civil aviation power ®∞to a civil aviation power.
However, although there ™★≈are many new technologies appli< ↕ed in civil aviation, flight dδ↔★elays are still common, and in♦±Ωcidents affecting aviation safety occas"✔ionally occur. The reason ♠÷ for these problems is n☆•ot that the technology is not§$> mature enough, but t'Ω&hat one of the most unfavorabl¶e factors for civil aviation s₩≤®afety-meteorological f±'actors.
| Bad weather conditions a&∞♦<re the main factors that ca×$>use flight delays and even affect a∞☆viation safety. According to interna©<∞αtional flight accident±"π statistics, meteorological factoπ≥rs account for about on'e third of the total number of accid∏≥ents, especially complex meteorologic™∏α♣al factors such as low visibi ♥ lity and strong wind pose¶₽≤€ serious threats to p∑≈ assengers 'lives and prε☆operty safety. |
Therefore, in order to prevent comple☆αλ x and changeable severe >₽weather from threateni±♥₽ng aviation safety, the Civil A♦≤↔<viation Administration has promulga♠λ←ted a number of mete↔→orological specifications, and airportλφ∏♣s have also increased the₩"ir investment in meteorological ₹® ←sensor observation equ©←↕ipment. |

| At present, the observati©©on equipment of meteor☆• ological sensor in civil aviati≠$↔on field has become one of the ×€±most important equipment in civ>©₩il aviation and even navigab•≈±♣le airport. The Guideγ≥≥δ to Construction of Meteorolo€ φgical Observatory of Civil A♣→★viation Airport requires that each run ↑way should be equipped wiσ &th automatic meteorological observγ↕λation equipment. |
According to the Technical Spγε™ecification for Civil Aviation Autom→>©£atic Meteorological Observation β±σSystem, the sensors of civil aviatio♥ n automatic meteorological↕§β€ observation system include wind d™&←≥irection sensor, wind✔≠ speed sensor, air pressure sensor, tπ↕emperature sensor, humidi ¶ty sensor, rainfall sens∏or, cloud height meter, a×≠α∑tmospheric transmittance meter or forwπ←>πard scatterometer, ba≈<ckground light brightness sen∞×φ♣sor, etc. |

| Obtaining wind direction, wind sp☆eed, air pressure, temperature,★≈γ humidity, precipitation, clo ∞®ud height, visibility and other info ¶↔rmation around the airpor♦∏t through the above met ↕₽eorological sensors, solving and ×uploading the data to the meteorologic>₽↑↓al observation data proα∞cessing system and se∏ ≠nding it to pilots, tower, " ↕maintenance and other relevant p×αγersonnel. |
The meteorological informat≠φ∏&ion collected by the obsε'ervation equipment of outfie∏&₹∏ld meteorological sensors can c♣→βlosely monitor the weather←♠ε conditions around t ∏he airport, make preparations in a✔π÷ dvance, and formulate various emer→¥♠gency plans in advance to minimize∏ the impact of severe weather on★><≥ flight operation and ensure safe ≈↑aviation operation.
