ya i understand what you mean about "folksy" language.
i was visiting beaver tower a couple weeks ago, and one pilot was a few miles north of the airport, she was kinda swerving back and forth, kinda circling around, while also struggling to understand what tower wanted her to do. apparently, she was on her 1st x-country solo, and on her way back, got off track, her squawk code was off, and was not sure what to do. the tower instructor gets on the mic, and simply says,
Tower: "cessna...., are you alright?"
Pilot: "ya, im ok, im on my way back from ..... and i know im off heading."
the instructor realizes that this gal is freaking out a lil, just walked her through the correct squawk code, where to fly, and when to report back to tower, using basic language, which i will highly bet is not standard phraseology.
Tower: "cessna... we have u on radar over this location, please turn to heading (###), and you will the airport off the nose of ur aircraft. once u have airport in sight, report back to tower."
i stood there and watched the ATC calmly and efficiently guide this girl back in safely. afterword, she came up to the tower and thanked everyone for her help.
i guess the overall point to this story is that it does not matter what phraseology an atc uses, as long as the action is handled safely and without violating rules.
