[Flightgear-devel] autopilot system

2003-02-27 Thread Mehmet Velicangil
My question is about the variables that are used in the autopilot system. As far as I can understand the target heading is calculated by the angle between the aircraft and the waypoint with the proper heading and the rate of change of angle times the distance between the coordinates which ar

Do you use any program to calculate the coefficients of rolling, pitching,yawing moments and the drag, lift and sideforce coefficients. The conf file of Cessna seemed so complete containing all of those coefficients. I am trying to change the aircraft properties for different types of airpla

2003-03-11 Thread Mehmet Velicangil
I have downloaded a matlab-simulink program that uses flightgear interface. For a flight dynamics model it requires external fdm so I command from that program and visualise in flight gear.  My question is how can I change the flight dynamics model to the external type. I read that batch fil

Firstly I want to thank you for your help in my understanding of the aerodynamic structure of the aircrafts. I have two questions about the aerodynamics model firstly I have a program that calculates lift and drag versus attack angle coefficients for a given parameterised airfoil and is it

If the heading mode is FG_HEADINGWAY_POINT does autopilot block use a similar procedure like in VOR or ILS navigation by using a rolling motion to intersect waypoint in a pre-determined heading or does it use the angle difference between its current heading and the heading calculated by t
