BUG Instant blackout

this is an old bug but it got really on my nerves today.

Sometimes there is just no linear progression in the blackout effect.

I pull and the black "circle" is not even half way when, suddenly: BLACKOUT.

This happens with every module and is the cause of far too many crashes.

It happens with any aircraft actually. More specifically, I've had it happen regularly with F-15, Su-27 and Mirage 2000 above 8 g. But also F-86 and Mig-15 at 7-8 g, and even in the P-51 (don't know how many g).

No track, I was in MP...

I've had it in mp too. I was pulling quite high g's then all of a sudden I blacked out without warning. This wad in a m2000c.

G-LOC behavior was changed some time ago, maybe already a year ago. If you pull lots of G sharply you will get sudden G-LOC with very little warning if any at all. If you pull G more gradually you will get the tunnel vision before G-LOC. Not sure if this is intended or not but it's definitely a bit annoying as there's no indication of G other than the G-meter and tunnel vision. The AGSM breathing only tells if you are above 4 G.

It is a genuine issue. Confirmed. The behavior is strange. Sometimes you just pull full stick and the pilot passes out before the vision is even half black.

Confirmed by whom exactly?

The tracks are needed so that proper analysis can be carried out. That makes your comment totally redundant, wouldn't you agree?

From the real life F/A-18 manual:

"Rapid aft stick movements, with or without G limit override, commands a very high G onset rate. This can cause immediate G-LOC without the usual symptoms of tunnel vision, greyout, and blackout. Consciousness may not return for more than 20 seconds after G is restored to near 1 G."

You can interpret this as you wish but I think current G behavior is pretty accurate. Apply G slowly and you're fine.

My take on it is that it is a warning: rapid stick movement can cause rapid unwanted G onset and instant blackout if you are unprepared. I.e. be careful with that stick.

When you're about to pull a high g turn you know what you're getting into, take a breath, tense your muscles, and pull. In that case I don't think you could experience an instant blackout.

I have aerobatic flight training, which includes a fair deal of theory and practice on how to take on medium/high g loads, and I haven't heard of instant black out. Quite the opposite actually.

For a small aerobatic pilot like myself, going from 1 to 7-8g quickly is not the problem. The problem would be to hold those 8g for a number of seconds. Luckily in a small Extra 300 there's not enough energy to apply 8g for more than maybe 1 or 2 seconds, then it rapidly decreases.

However, say I was a passenger, and the pilot suddenly pulls an 8g turn, I would probably black out much more quickly.

In our beloved sim, you could ideally push a button to "breathe & tense your muscles" before pulling. But that would be impractical and my hotas is already fully mapped.

I prefer our virtual pilot to be "always ready".

Also, it would be great to have something better to get a "feel" of how much our virtual pilot body is suffering. Maybe better and more varied sounds of the pilot grunting, so we have some cues to relax pressure before it's too late.

+1 for more 'pre G-LOC' effects.
