黑匣子可以人為關閉麼？

1樓：

排名第一的答案已經說明了。

cvr和fdr均可能有斷路器控制

斷掉電源之後就會停止工作。

cvr的內容可以手動清除

fdr據我所知還沒辦法手動清除內容

具體機型的斷路器配置請檢視fcom或者amm

飛行記錄器，俗稱黑匣子，包括飛行資料記錄器（FDR）和駕駛艙語音記錄器（CVR）兩部分。FDR用來記錄飛行中的最近25小時的規定引數資料，CVR用來記錄最近2小時的駕駛艙內的陸空通話，機組對話及駕駛艙內能聽到的所有聲音頻號。

當飛機的一台發動機開後，FDR和CVR將自動開始工作，而當最後一台發動機停車一段時間後，它才會停止工作，在飛機正常著陸後，飛行員可以抹除CVR裡儲存的語音頻號，但無法抹除FDR中的資料。

3樓：

(CVR) is designed to record crew conversations and communications into a memory

block unit in flight and on the ground, when at least one engine is running or

up to five minutes after the last engine stops irrespective of which engine

stops first. The system can also operate in manual mode on the ground. The

recorder is a four-track system and all tracks are recorded simultaneously.

The CVR provides storage

for 2 hours of consecutive recording for each of the four audio input channels.

When the memory block unit

is fully recorded, the system progressively erases recordings made in the

previous 2 hours and simultaneously records new information; thus only

information recorded in the last 2 hours of operation is retained.The recorded

information can be intentionally erased when the aircraft is on the ground with

the parking brake on, locked and electrically powered.Bulk erasure is also

possible during manual operation of the system. 也就是說320的CVR只能記錄最後2小時的語音記錄，而且該記錄可以被有意抹去，條件是飛機在地面且停留剎車剎上。

再說FDR，空客稱DFDR，介紹在手冊31-33中。

The DFDR is a solid state flight data recorder in compliance with ARINC 717.The

DFDR stores all aircraft information in CMOS bulk erasable EEPROM (Flash Memory

IC) devices. Being a solid state device, the DFDR has no moving parts. The

recorder has the capability to store all data which the FDIU (part of FDIMU) has

collected over the last 25 hours. It is possible to get a storage capability of

greater than 25 hours if the correct combination of SSFDR capacity and data rate

is used.

通過GND/CTL開關是可以抹去DFDR中的資料。

With the electrically latched GND/CTL button it is possible to override the

power interlock, so that the system can be supplied for preflight checks or for

maintenance and test purposes. The GND/CTL button is installed on the CTL PNL.To prevent the erasure of stored data, you must not unnecessarily activate the

override function of the power interlock.

DFDR也可以失效，即問題中的人為關閉，只需要拔乙個C/B（功能號7TU，位置是121VU面板K16）。

A.Deactivation of the DFDR

(1)Open,

safety and tag the circuit breaker 7TU (K16) of the DFDR.
