I have noticed recently GA pilots around Chicago have been cold calling with just their callsign. THANK YOU. Life is much easier when I can get the tail number punched into the computer, and then go back and ask what your intentions are after I take care of a base turn, or get a departure climbing off MDW.
To N1120As point. If you’re IFR, and you get ignored on your check in, don’t sweat it...there might be someone checking in on a different frequency, they might be coordinating with another controller, they might have a critical turn to make in a few seconds...ATC will definitely call you when they need you to do something. On the flip side, there might be a nasty buildup that hasn’t shown up yet on the radar screen as precip; get in there with a request for 20 right or whatever as early as you can so it doesn’t become an imminent situation.
Lastly, to expand upon the article...ATC will sometimes give control instructions to VFRs in class E airspace that might not make sense, or seem overly restrictive...there is ALWAYS a reason for such a thing. Expeditious compliance is always appreciated (when able), and then when the frequency is quiet a “how long do you need this?” if it is vastly different from what you want to be doing. I had a Mooney climbing VFR one morning with flight following toward a long line of ORD arrivals descending to 11,000. I restricted him to 9500’ for about 10 miles (he wanted 11,500). He promptly canceled his flight following, squawked 1200, and then the E175 he said he had in sight when I gave him the 9500’ restriction got an RA as he climbed into it.
At least around Chicago, GA pilots seem to be more patient the last couple of months; whether it’s knowing we are working with fewer controllers, or everyone is just enjoying the nicer weather, I don’t know...but all-in-all I think ATC and GA is working really well together right now, and I hope it continues through the summer.
