XXI. SPECIFICATIONS USED BY BLACK BOXES
The design of today's FDR equipment is governed by the internationally

recognized standards and recommended practices relating to flight recorders which

are contained in ICAO Annex 6 which makes reference to industry crashworthiness

and fire protection specifications such as those to be found in the European

Organization for Civil Aviation Equipment documents EUROCAE ED55, ED56 fiken

A and ED112 (Minimum Operational Performance Specification for Crash Protected

Airborne Recorder Systems).

In the United States, the Federal Aviation Administration (FAA) regulates all

aspects of U.S. aviation, and cites design requirements in their Technical Standard

Order, based on the EUROCAE documents (as do the aviation authorities of many

other countries. Thus these specifications must be considered for the design of all

new black boxes.

XXII. DATA STREAMING OVER SATELLITES - A PROPOSED DESIGN
Data streaming in general refers to the transfer of data at a steady high-speed

rate sufficient to support such applications as high-definition television (HDTV) or the

continuous backup copying to a storage medium of the data flow within a computer.

Data streaming requires some combination of bandwidth sufficiency and, for

real-time human perception of the data, the ability to make sure that enough data is

being continuously received without any noticeable time lag.

Data streaming and other data transfers to and from the satellite can be

streamlined and optimized by reducing or compacting the data files, or data set prior

to transmission to remote locations. Data streaming coupled with data compaction

provides for very effective transmission and at minimal cost of bandwidth and

resources.
