GENERAL
Pitot/Static Systems
The pitot/static system provides air data
sensing to the number 1 and 2 Central Air
Data Computer (CADC). The CADC provide
outputs of airspeed, Mach, altitude and
vertical speed.
Three separate pitot/static systems are
installed. The Captain’s pitot/static system
provides input to CADC 1, the FO’s
pitot/static system provides input to CADC 2,
and the auxiliary pitot/static system provides
input to the standby altimeter and airspeed
indicator.
The pitot tubes are mounted on top of the
nose radome. The static ports are installed
on both sides of the fuselage.
Primary Flight Instruments
The primary flight instruments are the
airspeed/Mach indicator, vertical speed
indicator, and altimeter.
CADC 1 provides input to the Captain’s
primary instruments and CADC 2 provides
input to the FO’s primary instruments. In the
event of a CADC failure, either CADC may
be selected to provide input to both the
Captain’s and FO’s primary instruments.
Inertial Reference System
The Inertial Reference System replaces the
directional and vertical gyros providing both
navigational and attitude data.
Two Inertial Reference Systems are installed
in the aircraft. Each IRS contains three laser
gyros that sense the angular rate of
movement about all three axis. The sensing
of angular rate is accomplished by
measuring of laser beam shifts within the
laser gyro units. Each laser gyro also contains
three accelerometers that measure linear
acceleration in all three axis.
The IRS units provide heading and attitude
input to the PFD/ND/RDMI as well as
navigation data to the FMS. The present
position of the aircraft is determined without
any external navigation aids.
Data provided by the IRS:
•
Attitude
•
Heading
•
Acceleration
•
Ground speed
•
Track
•
Present position
•
Wind direction and velocity
