Avionics Displays

The Primary Flight Display (next generation from the EFIS 40/50) combines EADI and EHSI data onto a single display. This design approach is to improve the flight crew‘s situation awareness via integrating multiple critical flight data onto a single screen reducing the amount a pilot needs to monitor multiple instruments. The Primary Flight Display (PFD) displays information critical to flight (which include the Basic-T navigational instrument parameters)

                             a) The aircrafts attitude information (pitch, roll, and yaw)

                              b) The aircraft indicated airspeed

                              c) Aircraft altitude information (Barometric Altitude)

                              d) Barometric pressure information (Baro setting/pressure scale)

                               e) Heading information

Mechanical gauges have not been completely eliminated from the cockpit with the onset of the PFD; they are retained for backup purposes in the event of total electrical failure.
