2.8.5 ALTITUDE TEST
1. Perform the installation and calibration tests in accordance with the altitude source manufacturer’s
installation manual.
2. Perform a flight check against the aircraft altimeter. Verify readings at ground level and at three
additional altitude points.
3. The altitude will be displayed on the bottom right-hand corner of the MFD terrain page.
2.8.6 COMPASS TEST
If the MX20 is located within seven inches of any compass, the compass will require a compass calibration.
2.8.7 STORMSCOPE INTERFACE TEST
If a Goodrich WX-500 Stormscope® sensor has been connected to the MX20, the interface should be verified
in the LT function on the MX20. Four standard Stormscope test screens are available to support system
checkout. Refer to the WX-500 Stormscope Installation Manual, P/N 009-11500-001. These test screens are
System Data, Self-Test, Noise Monitor, and Strike Test.
2.8.8 SKYWATCH INTERFACE TEST
If a Goodrich SKY497 or SKY899 Skywatch® sensor has been connected to the MX20 I/O, the interface
should be verified under the TRAF function on the MX20.
1. Turn power on to the MX20 I/O and Skywatch Unit. After the MX20 I/O self-tests have completed,
enter the Traffic Function by pressing the FN key until the TRAF menu option is available and press
the corresponding traffic smart key.
2. (If the TRAF function is not available, verify that the MX20 is an I/O model and that the traffic
function has been enabled as described in previous sections.)
3. From the traffic function, verify in the lower right corner of the screen that status of the Skywatch
unit. The unit should be either in the TAS Standby mode or no status should be presented. If a Data
Timeout error is presented, re-check the wiring.
4. From any function, verify that no amber SKYW annunciator is present in the upper left corner of the
display. If this is present, re-check the wiring.
