for question 5, your pilots will have to use FSPAX, Xacars, Kacars, FSFK or FSACARS(not supported but still can be used). Question 4, yes you have to import the navdata.sql file into the navdatatable. Question 3, you have to learn the times of each airport and country and figure out the time that corrasponds to the tiime in the UK then make the calculation that way. Also use the distance and average the time, as the time can fluctuate.for question 2, dont paint the stock 737 and 747 use the posky 747 and 737, they are the best freeware and look the most realistic. Also use the ifdg MD11 as that is the best that I know of. Question 1, it is up to you, pilots can use them or plot their own route. There is no way of forcing them to use the route you provide. Also make sure you are not using free hosts, as phpvms+free hosts = not very good. Free hosts tend to have certain functions turned off, that phpvms needs.
