I was just doing some fiddling with an aircraft configuration and just wanted to know what the parameter "flight director available" means under the autoplilot section.I have noticed some display 0 and others 1.I have tried both figures but have not noticed a difference in flight characteristics.Also should the default vertical speed entry under this same section match the entry in the airfile?For example one aircraft may show 700 in the cfg, yet under the autopilot settings in the air file the entry is 800.Sorry guys I am just a novice .Any assistance appreciated.Dimitri.

The flight director available flag simply tells the sim to supply data to the flight director IF the aircraft has an attitude indicator that features a flight director. You won't notice any difference in the way the aircraft flies...All entries in the aircraft.cfg are either "scalars" to use against the .air file entries, or are used instead of the .air file entries.

Thanks Bill for the information.Regards,Dimitri.
