GENERAL
The Flight Instruments System comprises the Air Data System (ADS),
the attitude, altitude, airspeed, and vertical speed indications on the
Primary Flight Display (PFD), the Flight Data Recorder System
(FDRS), and the Digital Clock.
The conventional flight data information is presented on the Primary
Flight Display (PFD).
Standby electromechanical instruments are provided as backup,
should there occur a complete failure in the electronic flight instrument
system. The standby instruments are Magnetic Compass, Airspeed
Indicator, Altitude Indicator, and Attitude Indicator.
Optionally the airplane may be equipped with an Integrated Standby
Instrument System (ISIS) that replaces the standby electromechanical
instruments (except the Magnetic Compass) in a single display.
