As a german Pilot I`m littlebit confused, where I`ll find the right Callsign for an Airport or CTAF Freq.
For example: I wanted to fly some patterns at KTRM. I loaded the sheet from the AFD and looked into Airnav.com. There I found the CTAF Freq. and the name of the Airport "Jacqueline Cochran Regional" but "Jacqueline Cochran Regional traffic" sounds strange, so i thought. On the Sectional Charts Cochran Regional is written only and "Cochran Regional traffic" maybe will work, so I thought. But how to pronounce "Cochran"? I took a quick look on Youtube what should solve the problem

After listen to it several times i was more and more confused, only by looking for the VOR-name gave me an idea what they called into the CTAF. Thermal!. By looking onto a streetmap I also found the Name Thermal Airport. But why I can`t find it anywhere within the AFD, Airnav.com or the sectional charts? Can you folks give me some tricks how I`ll find the right callsign?!
Thanks.
