CrashGordon Posted July 30, 2009 Report Share Posted July 30, 2009 I just imported some routes, and it would appear that the calculated distances are a bit excessive. For example the distance from PHNL to RJAA is 3886 miles, but the system is calculating 17944. It looks like the problem occurs as one crosses the international date line.

Administrators Nabeel Posted July 30, 2009 Administrators Report Share Posted July 30, 2009 Math was never my strong suit. I used an algorithm I found, but seems like that's causin probs. Any ideas on a good one to use? Quote Link to comment Share on other sites More sharing options...
CrashGordon Posted July 30, 2009 Author Report Share Posted July 30, 2009 That depends on how far I can dig into a web site that provides distances between airports. ;D The algorithm only fails where east meets west. Then, it appears to provide the distance going back all the way around the world. It's not the end of the world since it can be edited, but I thought you should be aware of it. BTW, I really like how the "import schedule from csv" feature works. I hadn't realized that if the airport wan't already entered, it would take care of that, as well.

Administrators Nabeel Posted July 31, 2009 Administrators Report Share Posted July 31, 2009 Yup, but try not to rely on that for obscure airports, and I'd add in the major ones at least. The script could hang up depending on your script execution time, but since it will overwrite existing schedules, you can keep mashing F5 until it finishes. The other is an interesting problem. I will have to research that. Thanks! Quote Link to comment Share on other sites More sharing options...
CrashGordon Posted July 31, 2009 Author Report Share Posted July 31, 2009 I keep the lists I'm loading reasonably short. I only learned of that feature when I did one of my (in)famous,"What happens it I do this?", routines. : ;D I had already added most of the airports we'll be using for the near future. I'm working on a spreadsheet that allows me to enter the aircraft's cruising speed and the distance route generation produces to provide the flight time, and (if I enter the departure time), the arrival time. that last part is still being ironed out. Time/speed/distance is a simple equation, but adding a fudge factor for 250 kts. below 10,000 ft and time awaiting takeoff, etc. is proving interesting. : Quote Link to comment Share on other sites More sharing options...
Administrators Nabeel Posted August 1, 2009 Administrators Report Share Posted August 1, 2009 Is the CSV file helping you out with that import? Quote Link to comment Share on other sites More sharing options...
CrashGordon Posted August 2, 2009 Author Report Share Posted August 2, 2009 The CSV file is very helpful when I want to create a lot of routes quickly that use different aircraft at different times of the day, but doing the same route. It is very easy to switch aircraft and change times. I can create 20 routes from one hub to 20 destinations using aE170 at 9AM, a B738 and noon and an A321 at 3PM, just by cutting and pasting.the flight numbers, aircarft and times. I added about 500 routes that way. Different pilots like different a/c so even if they are going to the same place, they get to fly what they like. Of course, when I want to get creative, I do them one at a time. ;D Quote Link to comment Share on other sites More sharing options...
