Hi guys (Jim?).Simple question. No doubt a simple answer.What is the point of putting the anticipated speed and altitude in the "Flight Plan Entry" pop-up screen?The fields are there, so I populate them, but I can't see how either affect what the flight plan is?Nothing seems to happen if I leave the boxes blank? Still get my route....Thanks.TimNZWN

Hi Tim,The altitude is used to calculate the average winds for the flight.The speed is used to calculate the time of the flight.Hope this helps,JimActiveSky Sales and Supporthttp://www.hifisim.com/images/asv_dev_team.jpg http://www.hifisim.com/images/asv_proud_supporter.jpg

Thanks Jim, knew there had to be an easy answer!!CheersTim
