Just to be pendantic.. ;-) wgs-84 is an oblate spheroid and an equipotential gravity model which is what I think we all meant by "round". I would image FSX also uses it, if not then this a definite plus
for you math types, it can be modeled using 2nd order Bessel functions for orbital mechanics/navigation JW > I think FSX uses a round earth model and non-flat runways as well. > > David > > On Apr 22, 2010 9:29 PM, "Curtis Olson" <curtol...@gmail.com> wrote: > > Here are a couple things off the top of my head ... > > - FlightGear is currently powering several FAA certified pilot training > devices (www.atcflightsim.com) > > - Flightgear uses a wgs-84 round earth model so you can fly from your real > aviation charts and hit all the intersections and radials and headings > right > where they should be. > > - FlightGear has all the stars in the correct place in the sky for the > current time and location as well as the sun and the moon and the planets, > and the moon with proper phase ... you probably didn't know that Durk. :-) > > - FlightGear's runways are not exactly flat ... just like in the real > world > they follow the lay of the land and there can be substantial differences > in > altitude from one end of the runway to the other. > > - FlightGear's autopilot code has been used to fly real UAV's autonomously > in the real world ... > > - FlightGear has some of the most realistic and complete helicopter flight > dynamics available in PC sims. > > - FlightGear has an awsome V22 Osprey model that is a total blast to fly > once you get the hang of it. > > - FlightGear supports multiple monitors on a single PC.
