|you will mainly use the autopilot to control the aircraft (since it has a real FDM it's kinda hard to control), and we would definitely recommend one with a developed autopilot (the 777s are really excellent with everything and has a good autopilot with all features you want). I don't fly in aircraft a lot, and like only three times with an autopilot, so I can't recommend any other aircraft with good autopilots. But one option with the 777 is that you could potentially use Nasal to dynamically edit routes that the aircraft just flies – not much work there. Another approach would be manually adjusting the autopilot parameters (like heading hold, bank angle, and stuff like that) through Nasal feedback algorithms for aircraft that don't have a.route manager. You could also couple this with the XML autopilot (now called "property rule") system to have real PIDs, easy lowpass, etc.<br/> | |you will mainly use the autopilot to control the aircraft (since it has a real FDM it's kinda hard to control), and we would definitely recommend one with a developed autopilot (the 777s are really excellent with everything and has a good autopilot with all features you want).

|there are two aspects to Nasal: that of interaction with itself and with the property tree. For your purposes, the property tree is going to be your communication with the wider FlightGear code. Nasal also can use its own mechanisms to interact with different things (file system, route manager, fgcommands, ...). In interest of the web browser analogy, XML in FlightGear is like HTML. Specifically it is responsible for setting up much of the property tree that FlightGear's subsystems act off of. David Megginson (creator of FG's property tree) once said that "XML should provide the nouns, Nasal should be the verbs" (or something, that isn't a direct quote) – so PropertyList XML is really good at providing data that Nasal can work off of. For like the fox2.nas script, this means that ideally all of the specific data about the missile would be taken from Nasal and stored in an XML file (which would be loaded by the Nasal file and the data would be copied over). | |||
