As you can see on the STAR chart of Adana, there is a letter "H" with a black background for the VOR sign's line. I can't find the meaning.
Customers have stated "We noticed an 'H' symbol next to an airspace fix/navaid in the SID/STAR chart planview. Explain what this means?"
The "H" symbol serves as an indicator for crews to look for a published holding pattern that is shown 'off flight track' in an inset.
