What's New

    The FAA has released a Draft version of Advisory Circular 150/5340-1K that will replace 150/5340-1J. There have been several changes to marking standards over the last few years, and many questions about those standards have been asked and answered through the SAMS (Signs and Markings Supplement). 5340-1K clarifies some of the old standards, as well as explains some of the new standards in greater detail. It also incorporates many of the guidance that is provided in the SAMS. Of particular note for Sightline is that Advisory Circular 150/5370-10, Section P-620 (the "how-to-do-it" of airfield markings for the FAA) is cross-referenced in several instances. That is significant because the leadership is noting the importance of application techniques. The new AC has also used colored call-out boxes to draw attention to specific criteria that should be considered.

    The Airfield Marking Symposium beginning in Milwaukee next week will incorporate discussion about the significant changes in this draft AC.

    DO NOT READ when sleep is imminent! However, we highly suggest that you do read it within the next month or two and provide your comments to the FAA. Click here to view the new draft.
