    I have DTK Auto Sync enabled in the PMSS50 GTN750. When activating an ILS VTF apch, the CDI switches from GPS to NAV1, but I am having to manually adjust the CDI's CRS after the switch. Is the auto sync limited to GPS in terms of CRS sync, or should I see it adjust to the crs for the localizer?

    Thanks for any guidance.

    The course pointer on the KI 525A HSI is not motorized, and should not move at all, unless rotated via the course select knob. Some GPS developers offer methods for aircraft developers to prevent this automatic alignment of the course pointer when it's not realistic, while others do not.

    Can you tell me how to access the 525A HSI's current CRS value, and if there is an increment / decrement event for it or whether this should be changed using a variable?

    Both can be accessed by the native variables and events:

    A:NAV OBS:1, degrees
    >K:VOR1_OBI_INC
    >K:VOR1_OBI_DEC

    You have me thinking regarding the KI 525A. Someone who is spending that much money on an aircraft equipped w/ a GTN750, RA, tip tanks, etc. is almost certainly going to invest in an CDI that has a motor and auto-aligns to the next leg in the GPS flight plan, do you agree? My understanding of what you are saying is the KI 525 doesn't have a motor for CRS changes, therefore you have to set it on every turn along a GPS FP in the actual aircraft?

    This seems to be even more of a question in my mind for someone investing in a (to-be) turbo prop kit. So if my understanding is correct, then do you have a different course deviation indicator instrument for the professional version coming soon?

    I'm not going to ask you "how soon" as I'm sure you get that all to often currently.

    Thanks for your perspective.
