It gives you a wind matrix of all altitudes for your airplane with associated fuel burn and ETE using the latest winds aloft averaging along the route. It's quick and very accurate as long as your airplane characteristics are programmed correctly which is easy to do. Ron ----- Original Message ----- From: bronnenmeier@GROBSYSTEMS.COM Sent: 08/24/11 02:36 PM To: lml@lancaironline.net Subject: [LML] finding the right altitude in a 4P Dear subscribers, One question bothers me for a while now and maybe someone can give me an answer on it. How do I find the right altitude with a head wind? Usually winds get stronger when you go higher - at the same time the plane goes faster when you go higher. If I think long enough I probably could come up with a solution calculating headwind components at different altitudes and comparing it with the 3 kts speed increase per 100ft (Craig Berland's number). How do you find your altitude without messing around for too long?
