Not sure if this question was for me or what definitively you were asking but...
All of the LT options are correct (LT ETAs, LT etc) except for the DTA.....LT 24 This adds 1 hr on to your input set time. This would be correct were we to be on British summer time, we are presently on winter time which is same as UTC.
Thinking further... actually if we were in future on British summer time then you wouldn't add the extra hour either as I would select the local time into the box..... PJ
Good idea, but what to do, if you have for example multiply VRPs. Czech airports have Alfa, Bravo, Sierra etc. There are in different folders, but if you write it, how to select the right WRP?
