How long does it take to plug in a transponder code? 3 seconds? Just do it.

To answer the OP.... I have had several declared "emergencies" in my time here, and I do not believe that we ever squawked 7700. Frankly speaking, I don't think it ever even occurred to us to do so. But as other posters have said, while being in radar contact, it is just one more thing that gets compartmentalized to the "do it later if I remember" folder. Any former ATC guys that might want to chime in as to the benefits (for us and/or ATC) would be greatly appreciated.

Times may have changed, but years ago I was taught that sq 7700 lights up the controllers screen and makes it hard to see what is going on around YOU. Therefore they didn't want you to squawk 7700 if you had already declared an emergency and if you were squawking 7700 to go back to your original squawk after they acknowledged your emergency.
Has this changed?

I'd much rather be talking to the controller, and him being able to see my callsign on the data tag. 7700 can wait for either if the controller tells me to, or if we got lost in a handoff, not talking to any controllers yet, etc.

I think that some who have contributed to the thread might not have realized that this was ressurrected from 4 years past!
I agree though, good discussion. Exactly the kind of *piloting* discussion that someone could learn something from rather than the mainline 90% type of discussions that go on here at APC.

In a previous aircraft, the transponder had standby, on, TA, RA, and emergency. To squawk 7700, you only had to rotate the switch to the emergency position. Another nifty feature was the "ATC OFF" option imbedded into the menu system which allowed for TCAS aircraft to see you, but ATC could not (except for basic radar return). Your tax dollars at work.

So I posted this over 4 years ago and, after its reserection, it seems most of us agree, it is not necessary to squawk 7700 if the controllers know about your emergency.
The genesis of the criticism our crew experienced was because the checklist specifically said they should squawk 7700. I don't know, but I suspect, the FAA believed they never even checked the QRH or they would have seen and complied with the check list item. Time has past since this incident and I have not heard much about it since.
