I’ve actually typed several replies to this thread, deleted them and then came back a few hours later or so later to rethink. From a personal perspective, torn. I’m saying this not only from VATUSA/VATSIM experience, but two decades of experience with online gaming organization management that often encountered the same double edged sword.
First, the positives. The concept is a solid one. Create a system allowing pilots to view when ATC will be online. Intent to increase participation, increase traffic and create an all-around positive development for the community. What’s not to like? Which is where it gets into the concerns...
Even today people do not necessarily review events posted on popular websites such as VATTASTIC (where they are spoon fed). I know I’m not alone in having witnessed an event in progress, massive traffic in an area, a flag posted for the advertised event and see someone ask in the chat box “What’s happening in (insert airport here)?” Person can’t even be bothered to click their mouse twice to look up the information. Is that a majority? No, but leads into a point others have raised…
VATUSA is not viewed by many pilots flying inside US airspace as a "popular public website" critical to flying online. This is no different than the fact a solid percentage of folks don't visit a local ARTCC website to review procedures before flying in their region. I question how valuable the resource would be from a practical standpoint.
Third, and this is two decades of online gaming organization management coming in. We can say whatever we want, but if the schedule isn’t going to be binding then it shouldn’t exist. Pilots will be within their right to complain people are on a schedule but not there. They won’t dive into the forums or our community websites to voice their frustration. It will be on UNICOM or chat systems and never present the opportunity for our leadership to reinforce the non-binding nature of the schedule. Not to confuse, I’m not saying it should be binding. I see a benefit, even if someone decides last minute to sign on they could at least advertise how long they plan to be online. But life happens and as most adults know, IRL takes priority compared to an online hobby that isn’t paying the power bills. Yet, sadly many on the network do not always display proper maturity in thinking. Just ask the controllers dealing with pilot complaints about why they are signing off after working a 4 hour event.
Finally, actually pulling from Matt’s comments, without a requirement it is doubtful controller participation levels will be what would be needed to turn the resource into something pilots would actually seek out before signing onto the network. When almost every ARTCC is making cuts monthly due to inactivity of controllers, we are talking about adding an additional layer of expectation voluntarily. If the resource isn’t being actively used, it creates a perception (truthful or not) about a lack of activity within VATUSA from those who spend perhaps 10 seconds a month on the website.
So I remain torn. I see potential for a centralized location advertising when people plan to be on. However, it gets complicated when folks don't always know their schedules, getting controllers to actually use it cannot be mandated, getting pilots to actually view it will be barrier to change and there are limits to how expectations about the system could be managed within the broader community.
