1 CIRRUS AIRPLANE MAINTENANCE MANUAL Display Systems CHAPTER 31-60: DISPLAY SYSTEMS GENERAL 31-60: DISPLAY SYSTEMS 1. General This section covers those systems and components which give visual display of conditions in unrelated systems. This includes the multi-function display, primary flight display, and Flight Stream 510. (See Figure ) (See Figure ) A. Multi-Function Display (MFD) Airplanes are equipped with either a Garmin GDU inch or Garmin GDU inch multi-function display. The MFD, located above the center console, depicts navigation, terrain, lightning, traffic data, NAV/COM frequencies, and annunciation information. All engine data is displayed on a dedicated ENGINE page. When the ENGINE page is not shown, all essential engine information is shown on an engine strip at the edge of the display. Redundant power sources provide 28 VDC for MFD operation. Power is supplied through the 5-amp MFD A circuit breaker on Main Bus 3 and the 5-amp MFD B circuit breaker on Main Bus 1. Either circuit is capable of powering the MFD. System start-up is automatic once power is applied. Power-on default brightness is determined by ambient lighting and is user adjustable. For additional information on the MFD, refer to the Cirrus Perspective+ Integrated Avionics System Pilot s Guide. (Refer to 5-00) B. Primary Flight Display (PFD) Airplanes are equipped with either a Garmin GDU inch or Garmin GDU inch primary flight display. The PFD, located directly in front of the pilot, is intended to be the primary display of flight parameter information (attitude, airspeed, heading, and altitude) during normal operations. The PFD accepts data from a variety of sources, including the MFD and the Integrated Avionics Units through a high-speed data bus connection. In conjunction with Flight Management System Keyboard, the PFD also controls and displays all communication and navigation frequencies as well as displaying warning/status annunciations on aircraft systems. During engine start, reversionary operation (MFD failure), or when the reversionary switch is selected, engine system information is displayed on the PFD. Redundant power sources provide 28 VDC for PFD operation. Power is supplied through the 5-amp PFD A circuit breaker on the Essential Bus 1 and the 5-amp PFD B circuit breaker on Main Bus 2. Either circuit is capable of powering the PFD. System start-up is automatic once power is applied. 1

2 CHAPTER 31-60: DISPLAY SYSTEMS GENERAL CIRRUS AIRPLANE MAINTENANCE MANUAL Power-on default brightness is determined by ambient lighting and is user adjustable. Typical alignment time is 60 seconds from battery turn on. In the event of a detected display failure, the Perspective+ Avionics System automatically switches to reversionary mode. In reversionary mode, all essential flight information from the PFD is presented on the remaining display in the same format as in normal operating mode with the addition of the engine indicating system. The reversionary switch, located on the center instrument panel between the PFD and MFD, may be used to manually activate the reversionary mode. For additional information on the PFD, refer to the Cirrus Perspective+ Integrated Avionics System Pilot s Guide. (Refer to 5-00) C. Flight Stream 510 The optionally installed Flight Stream 510 Wireless Gateway provides connectivity between the integrated avionics system and compatible mobile devices. Data output from the Flight Stream 510 can be used to provide additional situational awareness for the pilot and passengers. The Flight Stream 510 provides remote display of position, velocity, time, altitude, attitude, and heading. In addition, flight plans can be transferred between compatible mobile devices and the integrated avionics system using supported mobile applications. Up to four Bluetooth devices can be paired to the Flight Stream 510. The Flight Stream 510 is installed in the bottom slot of the MFD. If the optional GDL 69 SXM transceiver is installed, the Flight Stream 510 also serves as a wireless GDL 69 controller through which the aircraft crew or passengers can select Sirius/XM audio channels, control volume, and view SXM weather on compatible mobile devices. If the optional GTX 345 transponder is installed, the Flight Stream 510 also provides remote display of ADS-B IN, TIS-B, and FIS-B data. For additional information on the Flight Stream 510, see Cirrus Perspective+ Integrated Avionics Pilot s Guide. (Refer to 5-00) For an overview of the Perspective+ Integrated Avionics system, see Chapter 42, Integrated Modular Avionics. (Refer to 42-00) 2

7 CIRRUS AIRPLANE MAINTENANCE MANUAL CHAPTER 31-60: DISPLAY SYSTEMS (d) (e) (f) (g) (h) (i) NOTE In normal operating mode, a large red X through a data field indicates the data field is invalid. Valid data fields will not display a red X. At top corners of PFD and MFD, verify all NAV and COM fields are valid. On PFD, verify altitude, airspeed, vertical speed, TAS, and OAT fields are valid. Verify engine instrument fields are valid and read as follows: 1 Percent Power should read zero. 2 RPM should read zero. 3 Manifold Pressure should read the current barometric pressure ±0.5 inhg. 4 Fuel Used should read zero. 5 Fuel Flow should read zero. 6 Oil Temperature should read ambient. 7 Oil Pressure should read 0±2 PSI. 8 BAT 1 Current should read between 0 and 10 amps. NOTE Turn on large electrical loads (landing light, navigation lights, pitot heat, etc.) to ensure more amps are drawn when larger electrical loads are introduced. 9 Essential Bus Voltage should read 26±2 VDC. 10 Main Bus 1 Voltage should read 26±2 VDC. 11 Main Bus 2 Voltage should read 26±2 VDC. 12 CHT should read bottom of scale (All six CHTs). 13 EGT should read bottom of scale (All six EGTs). 14 ALT 1 should read 0 amps. 15 ALT 2 should read 0 amps. Press reversionary switch and verify both the PFD and MFD enter reversion mode. Both displays should have valid altitude, airspeed, vertical speed, and engine instrument fields. Press reversionary switch again and verify both the PFD and MFD are in normal display mode. Verify that no MANIFEST or CONFIGURATION alert messages appear in the lower right corner of the PFD (press the flashing ALERTS softkey to view alert messages).
