Hi Jim, Thank you very much for your prompt response. Yes, maths was never my strongest subject. I mucked it up in both paragraphs! It's furtunate then that I command an aircraft in the fs9 world only. Thanks again. Nick

Hello Folks, I have some questions about Historical weather data in ASE. This question relates to Online Historical Data. If I select a GMT hour for a particular date, does the weather then 'play back' the METARs until the flight finishes? So for example, if I select 29 August 2011 GMT 0100 to start and my flight is for 3 hours, will the weather at the destination be what ever it was at GMT 0300? I have in the past been using the Offline Static Data and, using the example above, would have selected "Multiple Dates/Times" and then downloaded 29 August 2011 0100; 29 August 2011 0200; 29 August 2011 0300 and 29 August 0400 (in case of any holding instructions...). I really want to clarify if the way I have been obtaining my historical weather data is the correct way or whether there is a quicker way of obtaining the METAR I want. It may or may not be relevant, but I have downloaded SP3. Regards, Nick
