For now they have to be in the schedule. Not a priority
I don't have any data to base percentage on. FSACARS doesn't supply it. I could fudge it, it's a possibility
Too complex. And there's no stoppage - you can conceivably have n number of classes for y number of aircraft, or x number of flights. I said average to indicate that across all classes, tickets will be an average across all classes. It's not a priority to drill down to that level of detail when across most VAs, it's not a requirement. Many VAs use FSPax to dictate seats and classes.
You can also indicate these stats (since that's all they really are), on a page. In the end, the system will derive an average (as it does for many values). This doesn't diminish the perceieved realism (maybe just to you, but this isn't build just for you). Everyone I have asked has no problem with this (haven't heard otherwise from anyone else either)
There's an EXE in that zip. I'm not going to open it. Don't post EXE files.
Anyway, the tools are there to create a route map that's as sophisticated as you want. You can do it through the API rather easy (watch the tuts). I've seen someone create a route map, using flash, completely using the API, pulling the routes and airport data (I don't remember who did it now)
Use existing forums
Bid criterea are possible, but again, the complexity in creating a rules system, I don't have the time for that. Notes are also there for a reason, you can note MTHF flights, and instruct to bid only based on certain criterea. You have the ability to accept/reject pireps for those not following rules.
Again, this doesn't diminish any perceieved realism, just tests the ability of your members to follow rules.
Central control for fuel prices is coming, as well as the load factor.
BTW, there are expenses, which you can add (monthly and per-flight, per flight can be all your landing and handling fees), and all other expenses can be drilled down (or up) to a monthly cost. If you read the docs, you can very realistically simulate real world expenses.
Taxes are planned, along with equipment purchase costs, and depreciation of value on assets. This can still be done monthly.
Features that MOST VAs won't use, I don't have the time to add. I'll check a few of those things out though. Thanks!
