newbe questions

hi mi new o this site and im just trying to figure out how it works. when i look at a map of my local airport and it shows some planes in the area are those actually live or is there a delay from the time it is really over a city till the time it shows up opn the map? also is there any way to set up the map so it is constantlly updating with out having to hit refresh?

Please read through and then see if you have unanswered questions.

~6min delay. My maps update but I’m not sure the frequency, every minute or so.
