State of Air Band and 8.33 KHz Channel Spacing in the US

[smcbmt]

The radio Reference article on the Air Band refers to the lack of use of 8.33 KHz channel spacing in 2012. Has it changed much over the past 12 years. Any need to bother to search with the 8.33 KHz step?

Here in the US? No. No need.

Hi, I’ve been wanting to ask since a long time… “no need” for same country flights, but what about international flights between North America and Europe, for example ?
How pilots deal with the 8.33 and 25 KHz spacing difference with their plane’s radios ?

Equipped aircraft can use conventional 25 kHz steps and 8.333 kHz steps. Thankfully it's not that big of a deal at all.

Here is a video of how it is typically presented to pilots, in this case on an Airbus a320. Notice how at the 15 second mark when he turns the inner knob it is going between 25 kHz channels and in-between it also uses the 8.33 kHz steps.

Not if you are only interested in air traffic control. There are a few other users on 8.33 kHz channels.
I don't think anything has changed since I posted this:

8.33 spacing questions

I was wondering if anyone here has an xls file with the 8.33 spacing from 108.000 to 137.000 that I can compare to what I did. I tried using something I found online but I am not sure its correct. It did say that with the 8.33 spacing I should get 2280 channels and I did get 2280 channels with...

It is coming. 2027-8, would be my guess for test sites.

Rumor has it they're all going around Palmdale.
