{{FGCquote|1= | {{FGCquote|1= What FlightGear is writing to those files is not actual "visual" stuff at all, it's just "gibberish" in the sense of properties that are only meaningful to FlightGear itself, and its features, most properties are in fact aircraft specific. Imagine those files to be containers for binary FlightGear properties, i.e. things like altitude, longitude, latitude - but also engine settings, flap settings, gear status etc.So there's really just numbers stored there, nothing visual that would make sense to visually re-interpret outside a flight simulator environment like FlightGear.To actually replay even just a single aircraft specific animation in FlightGear, you would have to write a python script that 1) loads the aircraft, 2) looks up the 3D objects, 3) maps the properties to animations - and completely ignore anything related to scenery, because it's typically just aircraft specific stuff that is recorded.|2= {{cite web | url = http://forum.flightgear.org/viewtopic.php?p=206610#p206610 | title = <nowiki>Re: Replay Conversion</nowiki> | author = <nowiki>Hooray</nowiki> | date = Apr 21st, 2014 }}}} | ||
{{FGCquote|1= the format is basically seralied FlightGear properties, please see $FG_ROOT/Docs/flightrecorder.README - these are all just "numbers", the format is determined by FlightGear, and these numbers do not mean ANYTHING outside FlightGear, and even inside FlightGear it's really just the flight recorder subsystem that is able to open/process those files, read in the numbers and map them to the corresponding FlightGear properties - which in turn allows things to be animated/replayed over time JUST VIA FlightGear. |2= {{cite web | url = http://forum.flightgear.org/viewtopic.php?p=206610#p206610 | title = <nowiki>Re: Replay Conversion</nowiki> | author = <nowiki>Hooray</nowiki> | date = Apr 21st, 2014 }}}} | |||
{{FGCquote|1= i would like to use the flight data recorded during the flight in the .fgtape format. However, i don't want to watch the replay but compare the recordednumbers of the replay with i.e. an ideal flight curve. For this reason, i'd like to extract the data from the file to work with it. How can i proceed? Is it already implemented in a way?|2= {{cite web | url = http://forum.flightgear.org/viewtopic.php?p=231739#p231739 | title = <nowiki>Extracting flight data from recorded flights</nowiki> | author = <nowiki>CasJanM</nowiki> | date = Feb 9th, 2015 }}}} | {{FGCquote|1= i would like to use the flight data recorded during the flight in the .fgtape format.
