Hello to all people who actually fly planes out there, I got a question:
When flying to or from some airport, how do you determine the maximum weight the runway can bear for your aircraft? Do you use PCN/ACN data or are there other means? I'm asking because for exsample the PCN data for KJFK (from http://www.worldaerodata.com) collides with the maximum weight for a 747 configuration, from http://www.airnav.com and I'm pretty lost.
It'd be great if someone could shed some light into this.
