ERAM is multichannel, which is why we do the failover between A-channel and B-channel during APL and OS CUTO. If I remember the SSMs right, we do the update on the B-channel first and once it has been approved by TechOps, A-channel is then updated.

Everything is built to provide a fallback in cause of failure, including the OS updates when they come in.

How are the interstitial ads handled in an OS such as this? Is the ad running time factored into the control system on the kernel level? Do the operators have a realtime safe button press to "skip ad" in high traffic situations?

When privatization is in the news, we like to joke, "I have a Venmo username to send $20 for a practice approach, advise when ready to copy."

Or, "Airlines123, ten miles from POINT, fly heading 360 until established on the localizer, cleared ILS Runway 1 approach. This approach brought to you by <advertiser>."
