All the code calculating the blackout is in Nasal/redout.nas. Adding a delay should be pretty easy.

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.

Agreed, and there is something annoying about blackout and HUD, when you can't see anything due to blackout effect, the HUD remains visible as nothing were happening... For sure that's not realistic at all :-) Alexis - 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=100&url=/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

Well, these parameters, can be customized.

Now when using any modern fighter with G-Suit , we get the same black-out than we have with aerobatic Aircraft. Which is wrong.

[Flightgear-devel] black out behavior
Hi, Ever since I switched to the CVS version of FlightGear I wondered whether the black-out behavior really is that realistic . Although I never experienced it I couldn't imagine this would happen in real life, at least not with an anti-g suit. In an excerpt from a nasa document describing a simulation involving black-outs I got the following piece of text: > blackout simulation: > The algorithm used a direct relationship between the algorithm of the > load factor a(n) and the algorithm of the time to blackout; the > simulation used 300 sec to blackout at 5g and 10 sec to blackout at > 9g, with simulatoed tunel vision during the interim period. Maybe this will help to make it more realistic.
