【 #機長廣播:當飛機遇上行雷閃電⚡️】
正如之前提到,惡劣天氣可能會擾亂飛行運作。今次就與大家分享雷電擊中飛機會造成甚麼影響。
一般情況下,機師在飛行途中會根據氣象雷達避免進入雷陣雨區域,以確保航班安全。但是天氣變幻莫測,萬一遭遇雷電擊中,飛機仍然能夠安全地繼續飛行,對機上人員和設備的影響非常微小,乘客可能只會聽到巨響而已。
這是由於飛機的機身由金屬導電材料製成,形成「法拉第籠」效應(Faraday Cage),令電流僅在機身外部流動,而封閉的機身內部不受影響。因為當雷電擊中飛機的機鼻、機翼或機尾等表面時,電流會沿著金屬機身流動,並通過機翼和機尾末端安裝的尖細靜電「放電刷」釋放多餘的電荷。此外,飛機的電力系統和油箱都經過特殊設計,能夠承受雷電直接擊中,進一步確保飛行安全。
機長提提你:雖然飛機能夠承受雷電的衝擊,但雷電擊中機身時,仍可能會造成洞口或裂縫。所以當飛機降落後,機師會立即向飛機工程人員報告,以便進行進一步的檢查和維修。
【 : When aircraft meets lightning⚡️ 】
As mentioned previously, severe weather can disrupt flight operations. But what impact does a lightning strike have on an aeroplane?
In general, pilots use weather radar to avoid entering thunderstorm areas to ensure safety. However, weather can be unpredictable, and if an aircraft unexpectedly encounters a lightning strike, it can still continue flying safely, with minimal impact on passengers and equipment—passengers might only hear a loud bang.
This is because the aircraft's fuselage is made of conductive metal, creating a Faraday Cage effect that allows electrical currents to flow only along the exterior of the fuselage, leaving the enclosed interior unaffected. When lightning strikes aircraft surfaces such as the nose dome, wings, or tail, the current flows along the metal fuselage and is discharged through static dischargers installed at the wingtips and tail. Additionally, the aircraft's electrical systems and fuel tanks are specially designed to withstand direct lightning strikes, further ensuring flight safety.
Captain's Reminder: When lightning strikes the aircraft's fuselage, it may cause holes or cracks. After landing, the pilot will immediately report this to the ground engineering crew for inspection and maintenance.
