For those who cannot handle realistic cutout an option for simplified cutout could be implemented and everybody would be happy instead of dumping down the sim aspect of the game for all.

What do you believe to be realistic cutout ? By that I mean cockpit indications, sounds and at what G should the symptoms commence ?

I think it's just fine.

...and I am a flying for half the beast for half the Hurri

Luthier had stated a long time ago that their records indicated the cutout should commence at 0.5g, but they reduced it to 0.1g as far as I can remember. I think somewhere between these would be a better compromise.

This has been debated in this forum at length. As far as at what G does the cut begin at that is documented at 0.1G i.e a 0.9G reduction from 1G flight...i.e. getting close to 0G*. The RAE flew a bunch of instrumented aeroplanes to determine onset thresholds as part of a study aimed at curing the issue. Here is a page from the report. Its available in the UK National Archives as AVIA 13/234 :

[*Edit replaced -1.0G with 0G]

Err not quite. G meters are accelerometers and in straight and level flight indicate 1G. As you start pushing they go towards 0G on the scale. Here is a G metre in a Yak 52 sitting on the ground i.e. at 1G.




0.1G would have the needle just above the 0 mark. Anything less than 1 is a negative acceleration.

My typo in previous post (since corrected) that means the G meter would be just above 0G reading 0.1G when the negative G cut starts.

May be a slight mvmnt frwrd of the pilot head each time the fuel flow is cut when the speed is high (>200mph) ?
