Re: [Flightgear-devel] English Electric Lightning no longer runs
Hmm - some kind of Nasal issue then? Any kind of error message? Vivian No error messages , it just stops with an Windows crash report. The dos window is, as usual, filled with the usual stream of annoying messages from traffic manager and navaids. At the moment I am looking at the electrical nasal code, but it could turn out to be the result of applying power to some system or instrument. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

Problem now solved !! In Lighning-electrical.nas, line 378 if(bus_volts 114){setprop(instrumentation/radar/switch,on );} Setting this to on crashes Flightgear on both my computers here. I can do the same by setting the property from the Browse Internal Properties menu. During my checking I have modified most of the Lightning's nasal files, especially the electrical file. These modifications were aimed at inserting missing nasal var statements. Also I have changed the battery charge integrator time constant as it was using milliseconds instead of seconds, and the battery was even worse at holding charge than my old laptop running down 1000 times faster than it should do!

Finding out whether this is due to the electrical switching logic or to some related effect in one of the aircraft systems is my next step. With the switching inhibited the afterburners seem OK.

Re: [Flightgear-devel] English Electric Lightning no longer runs
Alan Teeder wrote Using latest CVS on windows . The EE Lightning aircraft starts OK, all controls and views seem normal, but when the engines reach about 60% rpm Flightgear crashes. This fault is quite new and was not here about one month ago. For many month now I have been unable to run Flightgear in debug mode as it crashes in soundmgr_openall.cxx at line 486 :- if ( sample-is_file() ) free(sample_data); Erik is aware of this, but nobody else has reported this particular problem. This crash occurs before the cockpit view appears. Unfortunately this means that I can't find much about the cause of the crash. So far I have had a good go at the Lightning nasal files. The electrical system had no var statements, and one or two were missing in the others. All this to no avail. According to the lightning-electrical.nas file, the electrical generators should cut in at 58%, and this is my only clue. Does anyone have any clues?
