BTW: this code put into $FG_ROOT/Nasal/aircraft.nas would write an
aircraft specific value into autosave.xml. Not the operation hours,
though, but just the time fgfs ran with that aircraft.
var hobbs_store = nil;
settimer(func {
isletter = func(c) { c >= `a` and c <= `z` or c >= `A` and c <= `Z`}
var aircraft = getprop("/sim/aircraft");
if (!isletter(aircraft[0])) {
aircraft = "_" ~ aircraft;
}
hobbs_store = props.globals.getNode("/sim/time/hobbs/" ~ aircraft, 1);
if (hobbs_store.getType() == "NONE") {
hobbs_store.setDoubleValue(0);
}
hobbs_store.setAttribute("USERARCHIVE", 1);
}, 0);
setlistener("/sim/signals/exit", func {
hobbs_store.setDoubleValue(hobbs_store.getValue() +
getprop("/sim/time/elapsed-sec"));
});
