On the lift side of the screen is Airspeed Tape. It is not only showing airspeed in color-coded format, it is also showing TAS at the bottom; In the middle of the screen, Attitude Indicator spans the entire width of the PFD; On the right side of the screen is the Altimeter tape, it is showing the altitude in a tape with a black box in the center. Further right of the altimeter tape is is Vertical Speed Indicator (VSI); Below the Attitude Indicator is the Heading Indicator (a.k.a HSI- Horizontal Situation Indicator);
Turn Indicator, is showing quite different from traditional analog one – Rate of turn is combined into the Turn indicator and Inclinometer is combined into the Attitude Indicator.
- Outside Air Temperature (OAT) is detected by the OAT probe and then feed into Air Data Computer (ADC) for calculation of TAS;
- Attitude Indicator receives its information from the Attitude Heading and Reference System (AHRS);
- Heading data is measured by magnetometer, which feeds information to the AHRS for further calculation before showing on PFD;
- Turn Indicator’s data is measured by accelerometers, which feeds information to the AHRS for further processing before showing on PFD
