FSX and SDK

Hello people, Could someone more knowledgeable than I please answer a question with reference to FSX Standard. I would like to be able to use Airport Design Editor, but it tells me that I do not have SDK installed, I know that you get SDK in Deluxe versions, but is it possible to get SDK into FSX standard. And what else would be I need to install and display AI aircraft at certain airports . And if so, from where would be a good place to download and install from. Also being a bit cheeky, is TrafficX also available to download for free. ;)
