MoeKitsune Posted November 3, 2023 Share Posted November 3, 2023 Currently fuel prices for many short-range aircraft is bizarrely high, making realistically-priced routes impossible for them. I know the E-Jets, the Q400, and the CRJs have this issue, but there may be more. I saw on the discord that a new fuel model is being worked on, but considering the A320 has sensible fuel prices I think the root cause is a config error so that might need a look at before the new model is implemented. 2 Quote Link to comment Share on other sites More sharing options...
MoeKitsune Posted November 3, 2023 Author Share Posted November 3, 2023 Seeing as the possibility of unit issues was said in Discord, I think that if fuel units are supposed to be in gallons, maybe these planes have their liter number used instead. Would explain the ~4x increase in fuel cost of a 737 over a320 as a US gallon is around 3.8 litres 1 Quote Link to comment Share on other sites More sharing options...
sviridovt Posted November 4, 2023 Share Posted November 4, 2023 It's actually stored in weight, so in Kg (not ideal, not sure why I implemented it this way as it was years back). There are conversions involved in saving fuel costs so definitely an error prone process. I have to go through and check for errors. Might refactor this to a more sensible unit as part of fuel update. Quote Link to comment Share on other sites More sharing options...

No issues, I'll look into it some time this week, working on an issue with my development server at the moment. Quote Link to comment Share on other sites More sharing options...

I prefer to keep this unit. Quote Link to comment Share on other sites More sharing options...

That's probably why it is in weight as I was (am) quite a fan of flight sims so it was natural, but most sources use volume (liters, gallons etc.) when citing fuel capacity as well as fuel prices are typically volume based, hence to avoid errors it would make sense to use that.

Marco1887 Posted November 18, 2023 Share Posted November 18, 2023 (edited) Hi, I don't think the fuel price balancing is the only problem here. Sometimes I can't follow the flight financials. I link the latest case below. E.g. my route has a load factor of 100% and a net income of -200k. I increased the ticke price and the net income increased to -1k at 100% load factor. I increased the ticket price again and the the net income changed back to -200k at 100% load factor. https://prod.airsim.world/flights/research?orig=PEK&dest=DAC Edited November 18, 2023 by Marco1887 1 Quote Link to comment Share on other sites More sharing options...

The recalculations are weird until the flight updates. Quote Link to comment Share on other sites More sharing options...
Marco1887 Posted November 20, 2023 Share Posted November 20, 2023 I will have an eye on that Quote Link to comment Share on other sites More sharing options...
Marco1887 Posted December 6, 2023 Share Posted December 6, 2023 Ok, here is something: I set a scedule on a route, ticket price and IFS Profile. I updated (blue box) reloaded the page (blue box gone) and the loadfactor was 13k/13k in Eco and 0/2k in Busines Class. I didn't check the Supply/Demand ratio so I decreased the business class ticket price, updated (blue box) and reloaded the page later (blue box gone). After that the loadfactor was 8k/13k and 0k/2k. I did not change the ticket price for the eoc but the ticket sales decreased by 5k. Quote Link to comment Share on other sites More sharing options...
Marco1887 Posted December 6, 2023 Share Posted December 6, 2023 Sorry for double post, but I#m not allowed to edit my previous comment. Next weird fact: The Net Income was around 900k when the loasfactor was 13k/13k. After I decreased the ticket price for eco the loadfactor is 13k/13k again and the net income is now 1300k (business still 0/2k due to more supply than demand) 1 Quote Link to comment Share on other sites More sharing options...
sviridovt Posted December 8, 2023 Share Posted December 8, 2023 hmm, I wonder if it's still updating in the background but removed the box too early, these are the kinds of shenanigans I would expect if that were to happen. Quote Link to comment Share on other sites More sharing options...
Marco1887 Posted December 14, 2023 Share Posted December 14, 2023 I think I can proof your thesis. I recently edit an other route. The blue box disappeared and my profit was -11m$. I increased the ticket price and, after the blue box disappeared again, the profit was +14m$. I decreased the ticket price back to the privious price and reloaded the page about 10 minutes later. Now the profit is +4m$. Quote Link to comment Share on other sites More sharing options...
