Flight data recorder

1. Introduction It is very difficult, when an accident occurs during a flight to determine precisely what happened for several reasons:  Most of the time, during a flight, an aircraft is not in an environment where people cannot testimony what they saw (over water, high in the sky …)  When the aircraft crashes, it is often in an area difficult to access (open sea, on a mountain, …)  When the aircraft is ready to be examined, after being recovered from a difficult crash area or after a potential

of the most scrutinized pieces of evidence gathered from an aircraft accident is the collection of information contained in the Cockpit Voice Recorder and Flight Data Recorder. CVRs and FDRs paint an often haunting, but frequently useful picture of what occurred during the last minutes of an accident flight. This is not to say, however, that the recorders are always conclusive, or even useful. There are a handful of cases where the CVR and FDR tapes have broken, failed to record, stopped recording

discussed to improve crash location technologies. They are improvements to the ULB battery life, an additional low frequency ULB. Another technology is ADS-B which monitors aircraft position. Crash deployable flight recorders are also being considered as well as streaming flight data via a satellite. Let’s us take a closer look at each technology. There are several improvements to ULB technology in progress. ULB Battery Life is in the process of being extended from 30 days to 90 days. There

According to Rodrigues and Cusick (2012) humans are accountable for approximately 70-80% of aviation accidents (p.156). A majority of these are caused by the different variables associated with human performance. Psychological factors have a key role in a pilot’s everyday responsibility. Some of these traits include: perception, memory, attitude, judgment and decision making, as well as ego (Rodrigues & Cusick, 2012, p. 158-160). These qualities can have drastic effects in commercial aviation if

reliability in extreme case through tests and certifications. ICAO – A8 - 1.3 The flight recorder systems, when tested by methods approved by the appropriate certificating authority, shall be demonstrated to be suitable for the environmental extremes over which they are designed to operate. 1.5 The manufacturer shall provide the appropriate certificating authority with the following information in respect of the flight recording systems: a) manufacturer’s operating instructions, equipment limitations

These signals are gathered data processed through and flagged if the data does not meet the stored regulation requirements, which is where a diagnostic code comes from. On board diagnostics can range in cost anywhere from 300 to 30,000 dollars depending upon the equipment that the tool will assist in

3.2. DATA COLLECTION: The possible data collection using the on-board diagnostics tool can be categorized into different groups that may be of use to a variety of applications. Among all the details, most of the data which is relevant for used-car market would be the trip data that gets populated through the entire trip or usage of the vehicle. This covers the details of “trip duration, total kilo-meters travelled, kilo-meters travelled related to the type of road (say: regular motorways, urban areas

of logging and monitoring cyber-attack analysis is very important part need to be considered before choosing any software. There are four key phases which need to follow for effective cyber security monitoring as follows: • Collect relevant event data • Fuse events together • Analyze anomalous events • Take appropriate action Figure1: Four key monitoring phases The proper guide shown in the figure 2: Cyber Security Framework how to implement cyber monitoring capability which will support using

taken a few flights and our curiosity was extinguished by examining the parts of the plane that we can plainly see, and yet, there's this one aircraft component that we're still itching to see and know more about. Whenever a plane crashes, one thing that investigators want to recover is the so-called black box. But what is a black box and why is it very important? Read on and discover some information about this very intriguing plane component. More formally known as the flight recorder, black boxes
