MAINTENANCE MANUAL
5. EFIS
A. Meggitt Electronic Flight Instrument System (EFIS) - ( Optional in S/N’s 4636349 thru 4636374. )
(1) Electronic Attitude Director Indicator (EADI) [i.e. - Meggitt MAGIC EFIS Primary Flight Display
(PFD)]
The Primary Flight Display (PFD) is a microprocessor-based color, liquid crystal (LCD) display
system. Information displayed includes Airspeed, Altitude, Attitude, Vertical Speed, Heading
and Instrument Landing System data. The information is conveyed via predefined display
formats. In addition, the PFD includes built-in test, performance and health monitoring
functions and display brightness control. The PFD provides Gillam Code Altitude Output for the
transponder (Mode C altitude).
WARNING: FAILURE TO CONSULT APPLICABLE VENDOR PUBLICATION(S), WHEN
SERVICING OR INSPECTING VENDOR EQUIPMENT INSTALLED IN PIPER
AIRCRAFT, MAY RENDER THE AIRCRAFT UNAIRWORTHY. (SEE
INTRODUCTION - SUPPLEMENTARY PUBLICATIONS.)
Descriptions of the operator controls and basic operating modes and screens are in the
appropriate Pilot’s Operating Handbook Supplement.
(a) Troubleshooting
See Chart 5. See also Appendix 1 (grid 5K19).
(b) Basic Functional Test
CAUTION: IF, DURING THE FOLLOWING TEST, ANY COMPONENT DOES NOT
PRODUCE THE EXPECTED RESULTS, THAT COMPONENT MUST NOT
BE USED IN FLIGHT UNTIL THE PROBLEM IS CORRECTED.
1 Before applying power, verify proper voltage inputs and ground connections as well
as all system interfaces.
2 Start the PFD in Test Mode by pressing and holding the Baro Pushbutton while
applying power until the Initialization page is shown. Verify that the Initialization page
displays 'MIRAGE PRIMARY FLIGHT DISPLAY' at the top of the screen and is
replaced by the Configuration Data page after approximately five (5) seconds.
3 Verify that the Configuration Data page Configuration Discrete Parity Status and
Power On Self Test results both show results of Pass. If the result is FAIL, further
diagnostic effort is required to determine if the failed indication is the result of
improper installation, a faulty PFD, or both.
4 Verify that the Configuration Data page displays the correct installation location
(primary or secondary).
5 Remove power from the PFD to terminate Test Mode. Re-apply power to the PFD
and start the display in Mission Operational Mode.
6 Verify that the PFD displays the Initialization page for approximately five (5) seconds
prior to displaying the PFD Screen Format. If power has not been applied to the
ADAHRS then the PFD screen format will be replaced by failure indications.
7 Apply power to the Air Data Attitude Heading Reference System (ADAHRS) (i.e. -
AHRS).
8 Verify that the PFD Screen Format is displayed (if the ADAHRS is performing
initialization then the ADAHRS Initialization screen will replace the attitude sphere). If
any of the failure indications are displayed refer to Chart 5.
