This also allows you time to listen and make sure you aren't stepping on a conversation with your call. It also prevents this error since if you accidentally switch it to Ground they will come back and say wrong frequency dummy.
Yikes. Bad move for so many reasons.

Ever get the frequency wrong? Try and check in and no ones home? Now what are you going to do? Wait for New York to find you on guard?
Ever switch over and have the controller tell you the last guy gave you the wrong one and to go back to the last freq?

I appreciate the fact you wait before checking in because that is my biggest pet peeves. Guys who have their finger on the push to talk before they have switch the freq stepping all over everyone... That or people who check in, don't hear anything for an ENTIRE 5 SECONDS so they chirp in again. Chill. The controller knows you're there. 8)

No because I know the frequency before they give it to me. It's on the plate right in front of me. :lol:

Maybe it is. But that's in the airport environment. Once you train your fingers to do that, they will always do that; including in airspace you aren't familiar with. You'll learn one day.

I'm always familiar. The information is published and widely available.

"C-GPWG, an Airbus 320-200 aircraft operated by Air Canada, was conducting flight ACA781 from Montreal/Pierre Elliott Trudeau Intl, QC (CYUL) to San Francisco Intl, CA (KSFO) with 5 crew members and 144 passengers on board. After having received the proper clearance to land on Runway 28R at KSFO, the flight crew continued their approach and landed uneventfully. Following the landing and after the flight was handed over to ground control, ATC requested that the flight crew contact them by phone once the flight was secure. Subsequently, the flight crew was informed that the tower had unsuccessfully attempted to contact them while on final approach. The flight crew advised that they had not heard any calls after receiving their clearance to land. The operator is investigating the incident."

"A lesson to all Airbus pilots:
This is what could happen to you when you’re not careful while using remote tuning on your radio management panels."


I seem to remember a memo a while back on a particular fleet where I work about not using remote tuning due to some incident somewhere. I personally never use remote tuning. Seems easy to get it wrong.

I don't know the bus, but I do know many other aircraft, one of which where the ONLY way to tune radios was through a CDU. I suspect that would qualify as ''remote tuning''.

Let it rest, finger trouble happens. No matter what the technology.
It is a smart move actually. Assuming the link is accurate, one of the SFO guys used his resources and therefore proved how smart it is, by making national headlines. Yeah...that's the ticket. Evaluating which resources are helpful versus increasing risk of "finger trouble" is something we should all do instead of accepting that this is inevitable.

Your mention of types that have only one way to tune is useless to the discussion as it is the only option available :roll: .

Its only my suggestion but I will state it again(as applicable to Boeing's)...avoid the remote tuning. Not sure but I suspect Airbus is the same. I may just find out soon.
According to a source of mine...AC did send out a memo stating the same as what I suggested earlier on the thread which is....avoid remote tuning.

My take away is 3 lessons here....

Don't remote tune the radios. How hard is it to reach two feet across to tune a radio?
Don't have the company frequency on No. 2. In fact, don't have it on after landing while taxiing, the company already knows you landed and if the wheelchairs weren't arranged before 10 000', they can wait until the airplane is at the gate.
Instead of pre-tuning ground, have 121.5 on the #2. That is what people who are trying to get a hold of you will use if the normal freq doesn't work. It is also very useful if you have a problem and the atc freq is busy. Very useful in areas where English isn't native.

Maybe an AC pilot flying that fin number can tell us if there was an entry and if so, does it say ground checked serviceable for the sign-off.
A very credible source advised me the other day that no entry was made in the logbook because the radio was servicable.

In the end, an unfortunate error happened and as far as I can tell, once discovered was handled properly. Radio mistuning happens on occasion and I can guarantee you that every pilot that has posted on this thread has done it but were likely fortunate enough for it not to be at a critical time. As the PF or PM(or single pilot operation) in this situation, it can be difficult to detect, especially as there can be a tendency for the pilot to partially tune out radio information not directed to your own flight. Which is why I would expect neither pilot to be looking for a light signal.

Why would remote tuning matter? Whatever method you use, verify the frequency and establish contact. Seems like banning remote tuning is a bandaid fix that doesn’t address the root cause. These guys would have been caught with a KX-170 that didn’t quite ‘clunk’ to the right frequency.

We had a memo come out against remote tuning after some sort of an incident. Never heard the details but it was no doubt something about being on the wrong frequency. Guys still do it while setting up multiple HF frequencies but I always double check it in the non-remote state. It just seems to be much easier to make a mistake for some while others seem to have no problem. I doubt your statement about the KX-170 is correct.

Really? You’ve never tuned a radio and had it 25 or 50 kHz off because you looked away too quickly when tuning it or it got left off a detent or got knocked and went the wrong way?

Like I say, it doesn’t matter if it’s manually tuned, remote tuned, or auto tuned, you need to verify it’s the correct frequency before you hit transmit and that you hear the correct response at the other end. I’m a fan of remote tuning because I can do it faster that way and it’s rare that I’ve punched in the wrong frequency.

Thanks for proving me correct. It may be rare but likely more frequent than normal.
