Ok guys here we go again, this time i pinched a couple of posts off Dave's thread about engine out, and want to ask Ron to explain this situation at the end..

Now make sure everyone understands that we(Brian and I ) are talking about low level stuff here, as he said real low....
Now this just happened to me yesterday, its blowing about 30kts fairly constant, ok now im just flying around doin my thing,now because the wind is so strong im being abit cheeky and pull it it into a hover just above the trees to start of cattle no problems, as the wind drops off abit im slowly moving to far forward, so and THIS IS THE IMPORTANT BIT, ok im hovering at about 30kts ASI, so i open the tap increase it to 40kt ASI before i start to turn, by the time im in the turn it is 50 kts ASI, now normally full tap and 50 kts this thing climbs like a rocket, but all day yesterday, with the motor screamin and between 45-50 kts ASI turning down wind it would drop like a rock, and i made sure a few times that the ASI was up to make sure of this so i could come back and ask, and low and behold the subject was already on.
So can any one please explain to me why this is happening, and if you think im full of it, get on a plane and come over here and i'll prove it to you..
I'm not picking anyone here its just that Ron has said that it dont matter up wind or down wind if you keep a constant ASI, and i'm saying it does matter, and like Brian said we do it often enough to know when the machine is just not performing like it should....
Also the flying down wind thing needing more throttle is back on again to, dont know why but it does, about 300 rpm more
I'll be in and out for a few days so i might not get back to answering for awhile,, but i will be back

Theory is great stuff and most of the time it works very well, most of the time, when you fly low and I mean low as in zero feet agl to 100 AGL you are operating in an area that is subject to the turbulence caused by the wind blowing over terrain, trees hills etc then you throw in the effects of whirly wirly or dust devils, heat thermals and or hot weather, you bring in a lot of variable's that DO NOT conform to the theory we have learnt.
I do understand that a lot of you guys here might have trouble getting your heads around the fact that I have spent a lot of time in a gyro and a thousand hours or so in a FW, mustering and so have been subject to a few things that changed my mind on flying to the laws of theory, particularly when flying close to the ground.
I use the term 'downwind turns' cause thats what they are but to be technically correct, they should be termed "low level downwind turns and the effects that diferent conditions can have".
I'm going to get howled down for saying this but I have expereinced conditions [again, at low level] where it has been impossible to do a 'downwind turn', in fact I have on a couple of occassions, had to skim along at 10 to 20 feet AGL, not at full throttle but at a a power setting that should have had the gyro climbing at 300 ft per minute but the gyro would not climb and most certainly, had a turn been tried, would have seen me with a wrecked gyro. You dont find these conditions every day but they are there and if you are not vigilant, you will get caught, hopefully, you will hit better air and be your gyro suddenly starts to fly like it should.
Even FW get into trouble [down low] once in a while, its officially called 'pilot error' but when you read the pilots story, it generally says the aircraft did not seem to be operating at full power.
Anyway, I'm taking the heat off everybody else at the moment and I still have plenty of stuff to keep you shaking your heads for a while longer so stay tuned to reality gyro flying down low working stock.

Brian, flying that low to the ground, you are most certainly letting ground reference influence the way you fly. Again, if airspeed is kept constant, turning downwind or flying downwind is the same as flying in NO wind.
Maybe low to the ground with trees and buildings, all the wake turbulence may make it more dangerous to do some manuvering. But I still stand by my statement that if airspeed is kept in check you can fly as normal in any direction no matter how strong the wind is.
GUSTY WIND is a whole other animal though..... The wind is not a problem, but the gusts can be, but thats not the point.
Now make sure everyone understands that we(Brian and I ) are talking about low level stuff here, as he said real low....
