Pulling G's

[Mauler]

However, pull 2g for 30 seconds and you will black out!

In a balanced 60 degree turn you are experiencing 2g. So we'd all black out doing our PPL test after 30 seconds of this? Nope.

This has not been clarified yet. I often pull extended 60 degree turns and not once have I experienced any adverse effects.

I'll try!

The simple, (short), answer is that "you" are already more conditioned to pulling "g" than you realise. Your body is feeling the effects of the increased "g" load but it is able to aclimatise and adjust itself without a concious effort from you. This would normally not be the case for someone who has very little or no flying experience.

I was careful to make it clear that my response to the original question, ..... "what does it feel like to pull "g" in an aircraft" .... was not a difinitive discussion on the topic. It is a very complex subject, way beyond the scope of a couple of lines here. I addressed the article to someone who, I presumed, has very little or no experience of flying, e.g. a low-time pilot or a "ride along pax" or a "softness" or something.

There are some other thoughts on this matter which I will do some work on before I post.

Quite enjoy the "sensation" of "pulling g".

First time I experienced a loop in a harvard was very funny, the intercom was not working and I could not hear what the pilot was saying. We entered a shallow dive, I did not think anything of it, except that the power did not come back.. the next moment an enormous elephant snuck into the cockpit and sat on my chest... I faded away for a couple of seconds, I was completely unprepared... As we went over the top my senses returned and I felt weightless. The elephant had left.. but as soon as it had left it returned. I was again, slowly fading away.

Since then I have flown many aerobatic sorties and ejoyed all of them. Being prepared for the maneuver helps alot in enjoying the experience.

Unbelievable how this guy slips in and out of consciousness. Almost as instant as switching a light switch on and off

Going back to Thelsa's post about Cmdt. Jones flying him and a few others in a near-empty C130, in the Caprivi, surely he was playing with you guys in the back! Especially levelling out at 20 000' or whatever, there would have been no need whatsoever to make the transition from climb to cruise anything but a smooth one -- unless you were playing with your pax!



PS: ...but, you see, you <remember> it, don't you? You'll <always> remember it now...

After reading the posts about the RV7 which went down at Brits today, I thought it would be useful to newer members to 'Bump' this thread on 'Pulling Gs'

I am aware that the exact cause of the accident at Brits is not yet determined. Apart from medical / mechanical causes, the most likely cause is the effect of 'g'.

Noelotten,
Somehow, I missed the earlier part of this discussion until now..... In one of your earlier posts, you provided a huge amount of insight into the "G" effects. (Thank-you) I was also alarmed at one of the no-no factors being high / low blood pressure...... I never really thought of that before.

I suppose it would be fair to say that "G" exposure would put a higher strain on the heart and increased BP......For individuals susceptible to developing an Aneurysm, could this possibly be a trigger?

Maybe some of the Avcom medical professionals could shed some light.

NIce thread, thanks Noel. I, for one, am going to be watching this thread closely... *clicks-subscribe-button*

If you are worried about aneurysms negative Gs are the thing to avoid

Very sad los of yet another aviator!
Is a normal PPL medical sufficient to be allowed to do aerobatics?
Snoopy thank you for the link!

PJL

PJL,
A good question! May I suggest that you re-direct it to the "Pulling G" thread where we can debate this further? A lot more information about 'G' can be added for all to learn from.

Couldn't have been so bad, he was chewing more than Alex Ferguson right up until he passed out.

I woul've thought chewing gum and blacking out could lead to him choking ?

Noel, thanks for your post. Question I have - If you had a twin, and he was not subjected to the same G-forces your were, would he/she be older or younger than you...

Uhhhhh! .... Not sure what you want to know!

Are you asking if my 'imaginary' twin will <be> older or <look> older than me?

I am assuming you are not testing me on my understanding of the 'Theory of Relativity'.

Would he <be> older than me? If he was born before me he would be 'older' than me and if born after me, he would be 'younger' than me! And no amount of 'pulling G' would change that!

Would he <look> older than me is another matter altogether!!!!! If you pull too much 'G' when you are young you end up with bags under your eyes, sagging belly and a triple chin! ...... Nooooo!!!! I'm talking cr@p! That comes from eating too much!

I look the way I look because I had the 'right' <denim> genes! (Attached is a recent photo of me.)

I hope this answers your question. If it doesn't I'll try to come up with a better explanation.
