LOC frequency tuned
What did I do wrong if my tuned LOC in a LOC approach was identified but not captured by the AP.
By identified, I mean its identifier was correctly indicated in the top left corner of NAV1 of the G1000.
However, this LOC was not identified in the CDI bottom left corner (although Bearing 1 had been selected to LOC 1, CDI switched from GPS to LOC, and CRS value for the LOC correctly input. The AP annunciator did not show LOC mode while the bold green LOC arrow in the CDI began to show a displacement from course.
