Appeal No. 95-5063
Application 08/058,612
(Answer, page 1). Accordingly, claims 10 through 15 remain
before us on appeal.
The disclosed invention relates to a method of flight
crew alertness monitoring for an aircraft using a flight
management computer (FMC). An alarm is triggered when the FMC
does not detect any flight crew actuation of any of the
controls monitored by the FMC within a predetermined period of
time. The flight crew will also be alerted when the position
of the aircraft begins to deviate from a previously captured
active route with the lateral navigation mode (LNAV) engaged,
when there is a gradual thrust loss to a predetermined
percentage on any engine, and when there is roll or pitch
deviation in excess of a predetermined number of degrees from
FMC commanded roll or pitch attitude, respectively.
Claim 10 is illustrative of the claimed invention, and it
reads as follows:
10. A method of flight crew alertness monitoring for an
aircraft having a Flight Management Computer (FMC) which
requires no crew action other than normal flight crew
activities comprising triggering an aural flight crew response
alert when no flight crew actuation of any of the controls
monitored by the FMC has been detected by the FMC within a
predetermined time period after a silent flight crew advisory
alert has been issued.
