Making sure I have this right. 300XL GPS1 is set to aviation and is being understood by the AP(9600) and EFIS(AVTN/ARNAV) . However what settings should be used for the 300XL's AIRINC?
Inputs selections are : off, course, heading, course and heading ,selected course.
Output selections are: off, w/o gama , Collins PL2 EFIS, King EFS 40/50
I tried a few combinations but when selecting EFIS on the AP I get 'EXT LS VS'.
EFIS does show the AIRINC module with current software version.
*I can't call during business hrs from the plane.
