Absolutely - and I really don't want to get into an efficiency debate about Nasal (or, even worse, C++!) My concern is about maintainability - coming back to the 'nav-loc' example, this is a very general function, which the C++ code is supposed to provide. Working around C++ bugs or omissions is Nasal just seems unfortunate to me - it shows that on the C++ side 'we' (the C++ developers) need to be more responsive to requests from the Nasal/aircraft author side. (And yes, more frequent release would help) A related observation is that there is not much of a FG-sepcific Nasal 'standard library' for this kind of thing, so huge amounts of copy-and-paste goes on between aircraft. Sometimes there's five or ten copies of a given Nasal function in CVS, across different aircraft. If something is in C++, my hope is that people will prefer that to writing their own version. This is partly true for the autobrake case - by defining the properties in C++, it forces people to use a standard interface for the feature/instrument. If things are pure Nasal, authors *tend* to use their own property scheme, so that only the core (C++ properties) end up being generic and standard. This doesn't need C++ to fix, of course - just a better standards body to agree what properties and names are used.
