For sure that's not realistic at all :-) Alexis Coming back to the Erik, Alexis remark and my crazy first answer. Won't it be possible, to include in the Cockpit view parameters the additional parameters delay which gives the delay for 5g blackout and 9 g blackout ? and why not, if we want or not want, to have the Hud visible or not during blackout/redout ? That delay depends on the pilot :) (physical condition) Regards -- Gérard http://pagesperso-orange.fr/GRTux/ J'ai décidé d'être heureux parce que c'est bon pour la santé.

All the code calculating the blackout is in Nasal/redout.nas. Adding a delay should be pretty easy. Please go ahead. and why not, if we want or not want, to have the Hud visible or not during blackout/redout ? That's probably a side-effect of where the redout is applied in the scenegraph. I'll take a look once I've finished 3D clouds. -Stuart Send instant messages to your online friends http://uk.messenger.yahoo.com - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

May be, it could be delivered with the updated F-8E (new JSBSim) , probably not before next year (will depends on free time). I guess that somebody else could have done the Nasal/redout.nas modifications before. and why not, if we want or not want, to have the Hud visible or not during blackout/redout ?

Erik I have not the answer :( , so, having access to an external parameter/property ( evaluated and given by the Model Aircraft developer) which modify the conditions/values of black-out would be the best. Now when using any modern fighter with G-Suit , we get the same black-out than we have with aerobatic Aircraft. Which is wrong.

Cheers Oups, Oups, Oups, I did not take care of the Cockpit View parameters, which are new to me when we are not there a long time we are faulty ( so i am ). Well, these parameters, can be customized. My apologize and many thanks to the developer Cheers -- Gérard http://pagesperso-orange.fr/GRTux/ J'ai décidé d'être heureux parce que c'est bon pour la santé.
