The purpose of this paper is to study extensive enlargement and safety of flight data recorder memory.

The study involves the moving the memory of flight data recorders from an internal embedded device to a cloud.

The implementation has made the embedded memory device of flight data recorder effectively unlimited, and, hence, much more information can be stored.

The possibility of a flight data recorder to be damaged or lost in a crash is not so high, but the implementation can be very helpful in cases such as aerial disappearances.

The implication is larger and protected memory for flight data recorders.

Finding reasons for crashes is faster, and immediate actions can be taken to find remedy to the failures.

The use of internet and cellphones in airplanes is nothing special at present. It is suggested to take this technology for flight data recorders as well.

NOT until mandatory requirements in some advanced countries obliged airlines to fit flight data recorders did these instruments become fashionable. The needs of major operators coupled with the prospects of a world‐wide market spurred manufacturers to design and build airborne recorders for flight and operational data collection.

A RANGE or accident data recorders fully protected to TSO C51a has been developed by Fell Avionics to meet the present and future requirements for both civil and military aircraft, and which can readily be incorporated with any flight data recording system.

TELEMETRY is the science by which a measurement of a quantity is transferred to a remote location to be recorded, displayed or used to actuate another process. It typically involves the grouping of individual data measurements in a format that can be transmitted and or stored on a single medium, retrieved from that medium and separated into the individual measurements so they are available for inspection. If there is a more complimentary role for the modern data‐recorder it would be difficult to imagine it.

FOUNDED in 1956 by Mr E. L. Cook, Aircraft Supplies Ltd. have come a long way since then. Mr Cook left the flight test department of the de Havilland organisation at Christchurch to set up his own company to supply aircraft spares, particularly electrical items and aircraft flight instruments such as artificial horizons and other gyro‐based instruments. There can be few things more damaging to the airline operator than to have an aircraft worth hundreds of thousands of pounds grounded for a prolonged period due simply to the inability to obtain quick delivery of some small piece of equipment costing perhaps as little as a few pounds. The initial stores consisted of two hangars discarded by B.O.A.C. and the company was quickly established. As the organisation grew, it was able to offer full overhaul and repair facilities for instruments and electrical equipment and quickly obtained a reputation for the quality of their workmanship and the extent of their stock. Workshop facilities were approved by Mintech and the Air Registration Board gave approval for the manufacture, overhaul and repair of equipment for civil and military operators. A significant advance in the company's capabilities was made when it took over the manufacturing rights of the Midas range of flight data recorders in the U.K. This range of recorders was popular with airline operators wishing to meet the B.o.T. mandatory requirements.

In 1997, some 1.6 million CD recording units were sold. One reason is that you can now buy a CD recorder at a street price that starts below $400.

EXTENSIVE proposals recently issued by the FAA require installation of digital flight data recorders with specific parameters and/or cockpit voice recorders (CVRs) in a broad category of fixed and rotating wing aircraft. To be so equipped are aircraft operated by air carriers or commuters and in addition, certain selected smaller types operated in general aviation. Over the last few years a number of significant events have occurred that have necessitated the reconsideration of requirements. The NTSB considers that although recent rules have eliminated foil‐type flight recorders, concern is still felt about the adequacy of certain minimum standards. There is an urgent need to update the mandatory parameter list and to define new parameters, improved accuracies, range and sampling intervals.

CONSIDERABLE discussion has been generated over the years by the carriage and use of recorders of various kinds and the value of these aids to the investigative and preventitive authorities. It is now proposed by the FAA that additional flight recorder parameters be required for aircraft type certificated before 1969 and operating under Part 121. Also proposed is the requirement that cockpit voice recorders (CVR's) be carried on newly manufactured multi‐engine turbine‐powered aircraft certificated to carry six or more passengers, requiring two pilots by certification or operating rules for those operations conducted under Part 135. Also in the proposal is the statement that the Administrator will not use the record in any civil penalty or certificate action for those operators who are conducting operations under the appropriate regulations and have installed approved cockpit voice recorders.

RECORDS of aircraft accidents taken over the ten year period ending December 1969, indicate that outside of communist countries, 79 aircraft of all types, have crashed into water with the loss of 2,097 lives. Up to the present time in 1970, a further six accidents have occurred over water with the loss of 206 lives.

Undergoing final review this year by the ICAO Air Navigation Commission (ANC) are updated specifications for flight data and cockpit voice recorders that satisfy today's increased dependency on actual flight information in accident and incident investigation. The object of these specifications that have been developed in the last few years is to improve the effectiveness of flight recorders carried on board aeroplanes and to introduce standards for helicopters.
