Oxygen Panel “PBG”

[Burt]

Does anybody know if the PBG “Pressure Breathing for G’s work in the Viper ? I have been using it and it seems like it works alittle and shortens the blackout in high G merges ect.   I also use the 100% lever too.
I’m not sure if it’s just me thinking it works or not. Is it implemented yet ? Or will it be in the future. 
 

Thanks

From the manual:

Oxygen Panel
The oxygen regulation panel controls the flow of O2 to the facemask. The supply lever enables the system to be off, supply air in the on setting, or also include pressure breathing for G with the PBG setting. The dilute lever can be set to normal O2 mixture or 100% 02, and the emergency lever can set the system between emergency, normal, and mask test. At the top of the panel is a gauge that indicates the PSI of the O2 system.
