A flight recorder is an electronic recording device placed in an aircraft for the purpose of facilitating the investigation of aviation accidents and incidents. Flight recorders are also known by the misnomer black box—they are, in fact, painted bright orange in color to aid in their recovery after accidents.
黑匣子只是一個代名詞，實際上飛行記錄儀是被裝置在橘色（bright orange）的匣子內，應該被稱為“橘匣子”，只不過因為黑色不太好尋找，橘色波長較長，容易被觀測到。
The black box is made up of two separate pieces of equipment: the flight data recorder (FDR) and a cockpit voice recorder (CVR). FDRs record things like airspeed, altitude, vertical acceleration and fuel flow. The CVRs track the crew's interactions with each other and air traffic control, but also background noise that can give vital clues to investigators.
飛行數據記錄儀(FDR)和艙聲錄音器(CVR)。FDR記錄飛行速度、高度、垂直加速度和燃油流量等數據。CVR不僅記錄機組人員之間的對話以及他們與塔臺的對話，還記錄背景噪音，這些可為調查人員提供關鍵線索。
They are compulsory on any commercial flight or corporate jet, and are usually kept in the tail of an aircraft, where they are more likely to survive a crash.
黑匣子是商業飛機或公務機上的必備設備，通常安裝在飛機尾部，這樣更容易在飛機失事時保存下來。
This box is made of Titanium metal and is enclosed in a Titanium box which gives it the strength to withstand any shock if it falls in the sea or falls from the height.
黑匣子的外殼一般由強度極高的鈦合金制成，在從高處墜落或者掉入水中時，有極強的抗沖擊。
It can work for 30 days without any electricity. It can withstand a temperature of 1100°C. When this box is lost anywhere, it keeps on emitting the waves along with a beep sound for about 30 days.
它可以在不充電的情況下連續工作30天、可經受1100°C的高溫。無論丟失到哪里，黑匣子都會發射脈沖信號，并每秒發射一次"ping"信號，在電池耗盡之前可持續發射30天。
