Yes, I do that. But I also try not to teach young impressionable pilots that that is the Go-To method. Those @%$#%$ will do something wrong and then turn around and swear that you as an instructor taught them to do it. It takes one time and then the next time one of them gets the bright idea to deselect guard as a default every time they get in the aircraft.
There's a lot of criticism for something I admitted was a pet peeve of mine. Just don't blah blah blah all over guard channel. Good lord! How hard is that?
FWIW...yes, I have been called to do a 100% legit SAR for an F/A-18 pilot off the coast of Mayport when I was flying Seahawks in the pattern. No, the call was not over guard. It was relayed to us by Mayport Tower via Sealord. It earned me a nifty pin from Sikorsky, a letter from Sealord, and a case of beer for each of us on the crew from the Hornet squadron commander. But you never know. I have been doing this since 1985, civilian and with two different military services. I'm offering up a perspective that some of you might not have considered, and some of it is based on real world personal experience. You can listen to/read it, or ignore it. Hell, you can even make fun of me for having an old fogey attitude. You might be right. But the fact remains that blathering over guard does have a negative impact. That negative impact is greater for some more than others. Hence the pet peeve of mine.
Now that I have suffered irreparable P2SD (Post Posting Stress Disorder), I'll have to decompress with a glass of my
favorite bourbon when I get home. If you really want to watch me rant about a pet peeve, tell me how Jim Beam or Makers Mark are suitable substitutes.
