I just received this excellent question via email regarding the coverage area and thought I would share the answer I wrote with the forum as I think it might be valuable to a wider audience.
The question:
Do you all have future plans for expansion to maybe ZSE or ZAN? I'd love to fly 737 or heavies with a known staffed, professional ATC. I think it'd be well worth the monthly fee- or even if you could staff some of the international airports in the surrounding regions.. I'm just thinking ZLA/ZOA together might be a little small for fast movers
The answer:
If we find that we're getting strong traction from the sim enthusiast market and there is demand for pilots to stretch their legs over a wider area, then we'll look into it.
It costs [a bunch of money] to staff each facility. That's [many, many] additional subscriptions just to break even, and doesn't include the expense of actually developing the procedures for each facility.
"High quality ATC" is something that takes a long time to develop for each facility, so the decision to open a new piece of sky is not something we can make lightly.
I have plenty of time flying online in a wide variety of planes. My observation is that there's actually close to 0 work to be done during the enroute phase of flight. All the action is really in the departure, climb, descent, approach and landing phase. I would argue that once you go beyond a 1hr end to end flight, there is a diminishing return on the time invested in the flight (in terms of education/training). For that reason, I feel as though having ZOA/ZLA with 200+ public use airports and 600x400nm of airspace should be a reasonable environment for just about any pilot. A flight from KRDD to, say KSAN or KNYL will take at least 90 mins in a 737.
Now, I agree that the time might come where you start running out of class Bravo airport city pairs, however, if you broaden the list to include Class C and Class D fields, you could come up with a massive list of potential flights to do on the network.
Step down into a 280kt turboprop, and the airspace becomes much 'bigger', too. Just a thought!
I absolutely understand your request, and once we launch, we'll see how things go. I'm open to it, but it's a very tough decision to make.
What is most likely to happen is that if we do expand, it'll be over on the east coast, simply because that is the second largest concentration of GA pilots in the country, and this is primarily aimed at real world student pilots, instrument students and rated pilots who are looking to raise their game and stay sharp.
I hope this helps!
