SEAToday.com, Jakarta - Pernahkah Anda menyadari keberadaan lubang kecil di jendela pesawat? Anda tak perlu panik, karena ternyata ada alasan keselamatan di balik kehadiran lubang tersebut.

Dilansir dari Business Insider, tekanan udara menurun saat Anda berada di ketinggian. Namun, pesawat terbang dirancang untuk menjaga tekanan udara pada tingkat yang aman di dalam kabin.

Jadi, tekanan udara di luar pesawat jauh lebih rendah daripada di dalam. Perbedaan tekanan udara ini memberikan banyak tekanan fisik pada jendela pesawat.

Jendela pesawat terdiri dari tiga panel terpisah. Panel luar menangani perbedaan tekanan udara ini.

Berkat lubang kecil di panel tengah, yang dikenal sebagai bleed hole atau "lubang pembuangan." Tujuan utamanya adalah untuk menyeimbangkan tekanan udara. Terdapat celah kecil di antara panel tengah dan luar.

"Lubang pembuangan" ini memungkinkan tekanan untuk menyeimbangkan antara kabin penumpang dan celah udara. Artinya, panel luar menerima tekanan sementara panel tengah bertindak sebagai pengaman.

Panel bagian dalam bersifat "non-struktural", tetapi membantu melindungi panel tengah dan luar dari kerusakan yang disebabkan oleh penumpang. "Lubang pembuangan" juga melepaskan uap air dari celah udara. Hal ini mencegah jendela berkabut atau berembun.
