Added the L parameter now also to the RouteMapT and RouteMapF-pages. It is now possible to define the value directly from the initial pages (view/find) and it is no longer needed to add the parameter manually to the URL.
To explain the RouteMapF.asp page a bit further, here is an example:
This page is to find a suitable airport within a given time frame.
Let's assume, you have Superjet with a base in Chengdu, China (CTU) with an empty time frame of 360 minutes (6 hours) in the schedule. Assuming, that the turnaround time for the aircraft is 60 minutes you can fly a maximum of 150 minutes (360 mins - 60 min turnaround divided by 2) from your origin airport. So you would enter the following parameters on the find page:
Speed of your aircraft: 830 km/h for a SuperJet
Time: 150 mins
Bandwidth: 60 mins (determines the thickness of the donut)
Circle 1: 10 km (to have it out of the way)
Circle 2: 20 km (to have it out of the way)
Line width: As desired, I chose for the example 0.7
You will see the above screen. The red "donut" shows you the airports that you can reach within that time frame. The red lines show the routes that you already serve, while the airports without lines are potential new destinations that you can use to expand your network.
Does that explain it enough?
