TLAR help
Can someone elaborate on the formula GAG=GAA(airspeed +/- wind)/airspeed
I'm a little confused on what GAA is and if it's just a constant number. I kind of derived it as being 30 degrees as a constant target of angle you want to the touchdown point (?). it works for Tom Knauff's calculation in his book with 50mph a/s and 30 mph headwind, and using 30 for GAA. but when I reduce it to a 5 mph headwind the resultant doesn't come within the cone. Am I missing something here? ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =----
