content: The Aviation Safety Council (ASC) built up the Investigation Laboratory (the Lab) in 1999. The Lab was expected to perfect the readout capability of light recorders through yearly survey on the installation of recorders of domestic airlines. The main function of the Lab is to readout the flight recorders of an accident or a serious incident to help determining the probable cause and improve our aviation safety environment. The guideline was enacted for national resource sharing and to provide service to the industry for domestic or foreign agency.

2. Readout Capability 2.1 Basic (1) Cockpit Voice Recorder (CVR) readout – tape or solid-state (2) Flight Data Recorder (FDR) readout – tape or solid-state 2.2 Advance The purpose of building up the Lab are: (1) To establish local readout ability to shrink time spending on flight recorder readout and analysis; (2) To develop time synchronization and wave data dealing skills; and (3) To combine the satellite images and real aircraft cockpit 3D modules to make animation for investigation. Therefore, the Lab has established the readout and analysis capability for flight recorders. The tool use for FDR readout was Recovery, Analysis and Presentation System (RAPS) developed by Canada TSB in 1986 and used by many accident investigation agencies. The Lab developed its own Digital Terrain and Flight Animation System (DTFAS) combing the satellite images, instrument panels, 3D airport and aircraft modules (under development) and animation ability. Airplane Performance Analysis System (APAS) is used for the performance analysis including flight path calculation, landing and takeoff performance analysis, function of stick to control surface, computed airspeed, altitude or AOA…etc.
3. Guidelines for Readout Service 3.1 Client The service is mainly provided for the domestic agencies, airlines and foreign agency. 3.2 Right and Obligation (1) The Lab should deal with the readout data in confidential. (2) The Lab does not take the responsibility for the data loss caused by incidents or human errors. (3) The Lab would provide a readout report as attachment 2 as necessary after the readout is done on the occurrence recorders. (4) Applicants need to fill the form as attached form 1 and the Lab will manage according the demands on the form. (5) The Lab will inform the applicants to bring back their recorders after the task completed. (6) The Lab did not charge for the readout service for now but the applicants need to prepare the media such as VHS tapes, VCD/DVD disks or MO disks, etc. 3.3 Process (1) Other than the ASC itself, all applicants should send an application as attachment 1 to the Lab. (2) The Lab will arrange the schedule according to its workloads. (3) The applicants should bring the related software or hardware to the Lab and the Lab will sign and take notes on the application when receives the recorders. (4) The applicants should provide information as following: ?? Flight plan and basic information of the aircraft ?? Related FDAU documents and the FDR parameter database including hardcopies and digital files. ?? Related information about the aircraft performance, navigation, control surface and warning systems such as stick natural position, elevator Vs, CCP, aileron Vs, CWP, localizer & glideslope, GPWS and stall warning…etc. ?? Provide necessary assistance when transcribe the CVR recording. ?? Provide a serviceable and same type recorder for backup when dealing with a solid-state recorder.
