Flight figures updated

Testers take note: I've just made some changes to the figures used for flight calculations, so some of you may find that your carbon footprints have leapt up a bit (mine has)!

I was originally using DEFRA figures for aviation emissions, but they do not take into account the extra effect of releasing greenhouse gases at high altitude, which is estimated to be around 2.7 times higher! I've found some better figures, so hopefully the new numbers will reflect better the actual climate impact of flying. I've also added the ability to select your class of seat. First class seats take up around 3 times the room of an economy seat, so if you choose to fly this way, your emissions will be 3 times as high!

I'm trying out a new graphing engine this afternoon, and if it works, then hopefully I'll be able to release flights across the entire site later on today!

Air travel in testing

It's been a while coming, I know, but air travel has finally been uploaded onto the site. At the moment, it's only open to testers (if you want to become a tester, let me know). It needs a bit of use before I can confidently release it generally, but rest assured that it won't be long now. Also, in the same update, there are a bunch of changes to the profile page and calculation engine. It now takes into account up to a whole year of data if you have it, and it handles inactive accounts (i.e. old cars) much better, so in general the figures should be more accurate. You can also see a list of your top actions on the profile page, so they are a bit more accessible and obvious. I hope you like the updates, and as always, please send feedback through the forum!
