Would it be possible to convert base Airbus/Boeing models to their enhanced versions (fitting whatever form of winglets, essentially) as is often done in the real world?
Still no range & payload chart available from Embraer.
Yes, it would depend on the base model and ideally would only vary by the winglets. Very large families of aircraft pose a bit of a challenge due to how many variants were made.
Hi @Priller , really appreciate the work you’re doing here, but wanted to flag up an issue with performance, at least as conventional wisdom would dictate.
On Paine, both the A319Neo and A220 are on performance V1.5, however, when you run the two aircraft through the evaluation tool, the A319 Neo light is either matching or in some cases beating the cost per seat and the fuel consumption of the A220. This doesn’t feel right, given pretty much no real world airlines are opting for A319Neo over the A220 - almost always (in publicity statements) because the A220 is markedly more efficient.
Could this be investigated when you get chance? I’m sure if this was the situation in reality, the A220 wouldn’t be anything like as popular/the 319Neo would be substantially more popular.
I’ll take a look at the A319Neo & A220 performance numbers to verify and I’ll address if I find anything.
As far as the Aircraft Type Evaluation tool might be a @martin question and how the tool works. Available Seats appears to be based off of max certified pax and the tool gives me 3 different prices for the same route with no way to control either. I’ve been in the habit of using the Performance Check Tool for so long that I don’t use the Aircraft Type Eval tool when comparing aircraft. Too many variables that I’d rather figure out myself. Maybe @martin will fancy it up for us sometime in the future.
“more efficient” in terms of fuel consumption or “total costs”? Because the latter is a whole different story and nothing Priller can do anything about
As far as the aircraft type evaluation is concerned, both. The A220 uses more fuel, and is sometimes overall less efficient (or more often, approximately equal) per seat than the A319NEO light. This doesn’t feel quite right, as the A220 is famously more efficient than the A319, to the extent that Airbus is said to have killed their own product in acquring the C series program.
Because I don’t typically work with aircraft data all that much (thanks to Priller ), could you be more specific and provide some concrete routes and the exact aircraft variants you’re comparing? Then I could have a quick look and try to get a feel for it.
Sure thing - I was looking at the A319NEO light vs A220-300 on a number of European routes from BRU, of varying lengths (eg: BCN, HEL etc). As I was considering my fleet strategy going forward, I was comparing on a variety of different length routes and the outcome was always very very similar (often within $1 per seat and almost always with the A220 consuming more fuel). My usual strategy with the type evaluation is simply to have 0 year old aircraft and standard seats input, as I’m very much comparing which aircraft will best suit my operation as a new purchase.
From what I can tell the changes wont be massive but it’ll be as close as I can get it performance wise. There were some changes between APMs and the A220s had some minor changes to weights so I updated them to the config current with the latest A220 APM from Nov 2025 (The latest one currently published).
