جعبه سیاه هواپیما چیست؟

جعبه سیاه هواپیما

در هر هواپیما، دو دستگاه ویژه وجود دارد که جزئیات لحظه به لحظه پرواز و مکالمات جاری در کابین خلبان را ثبت می‌کنند. این دو وسیله در جعبه‌های فولادی مخصوصی قرار دارند که به آنها «جعبه سیاه» می‌گویند.

 

داخل جعبه‌های سیاه را با موادی عایق‌بندی می‌کنند که تا 1000 درجه گرما را می‌توانند تحمل کنند. ضربه نیز بر این جعبه‌ها تاثیر نمی‌گذارد و آب تا مدتی قابل توجه، به درون آنها نفوذ نمی‌کند.

 

جعبه مربوط به ثبت جزئیات پرواز در قسمت دم هواپیما جای دارد- در صورت بروز هر حادثه هوایی یا سقوطی، دم امن‌ترین قسمت هواپیماست. این دستگاه دمای داخل هواپیما، شتاب و جهت پرواز، صدای موتورها، جهت و سرعت وزش باد، ارتفاع پرواز و بسیاری از مشخصات فنی دیگر را هر لحظه ثبت می‌کند.

مکالمات داخل کابین خلبان، صدای انفجار و صداهای ناشی از هر واقعه دیگری در هواپیما را نیز دستگاه دوم ثبت می‌کند. به این ترتیب، اگرهواپیما دچار حادثه‌ای شود، اختلالی فنی در آن بروز کند. انفجاری در آن صورت گیرد، سقوط کند یا مورد حمله هواپیما ربایان قرار گیرد، با بررسی اطلاعات ضبط شده در جعبه سیاه می‌توان علت وقوع حادثه و سیر جریان‌های رخ داده در هواپیما را بررسی کرد.

البته جعبه سیاه به هیچ وجه سیاه نیست. بلکه رنگ قرمز روشنی دارد تا پیدا کردن آن در محل حادثه آسان‌تر باشد.
