standing or falling together, arguing separately only claims 1,
3, and 4.
Benn discloses an aircraft flight data system for
visually displaying flight data directly from an aircraft flight
data recorder that has been removed from an aircraft (col. 1,
lines 11-15). Benn explains that
[t]he primary purpose for recording aircraft flight
data is to provide flight data for accident analysis
but the flight data recorded on the aircraft has also
proven useful to airline management for other purposes
including aircraft maintenance and incident analysis
such as a landing approach resulting in a hard landing
or a go-around. With the advent of modern digital
flight data recorders, that are capable of storing over
a hundred different flight parameters, the usefulness
of the data to the airline operating and maintenance
personnel has expanded dramatically. The availability
of a large number of flight parameters has made
possible significant improvements in the safety as well
as the economics of flight operations by permitting
management to analyze actual flight data. However, in
order to be useful, this data must be made available to
management in a timely manner and in useful formats.
[col. 1, lines 19-35.)
Referring to Figure 1, Benn's invention is a data display system
that reformats the flight data stored in a flight data recorder
10 or an optional copy recorder 14, converts the reformatted data
into engineering units, and then displays values these values,
including altitude, heading, acceleration, and speed (col. 11,
lines 32-34), on a cathode ray tube 26 in either the graphical
format shown in Figure 3 or the cockpit instrument format shown
