    Altitrack issue

    My Altitrack has started behaving erratically. The battery is fine so it's not that. The digital readouts on the back are OK, but the analog needle on the face goes (consistently) to the wrong place, about 4,700ft, when I turn the unit on. If I remove and replace the battery, the needle ends up consistently around 16,000ft. If I reset the unit the needle goes all the way around the face and ends up consistenly in the wrong place. I have discovered that the following sequence gets the needle to the zero: reset, turn the unit off, turn it on again. It then stays correct for the rest of the day, but after it shuts down, the next morning when I turn it on the needle goes back to 4,700ft ?????

    Pilot7 canopy

    Has anyone experience with the Pilot7? And if so, what do you think of it, and the various fabric options?

    Do Canopies Naturally Turn Upwind?

    Sorry, that is just evasion. An object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The path over the ground establishes the motion and speed, and the wind shear sets up the unbalanced force. Do the math.

    Do Canopies Naturally Turn Upwind?

    Explained in great detail in the thread previously linked. And you never answered this question: "What happens if you are flying on a heading of 360 in a 150kt wind from 090 and rapidly descend into a layer of 20kt wind from 090? No autopilot, hands off the controls." Break out your E6B which you probably last used 18,500 flight hours ago and do some vector algebra. And don't forget Newton's 1st Law.

    When was the last time the wind was constant all the way from opening altitude to the ground?

    NEWTON'S FIRST LAW. Think about it. You may have thousands of flight hours, but Newton has yet to be proved wrong in non-relativistic or non-quantum situations.

    . Nothing to do with that. The vertical tail causes the nose of a plane to turn into the relative wind. So if the relative wind is coming from the side, the plane will turn towards that side.

    But planes aren't designed that way. They have large vertical tails.

    But what if its a crosswind and the wind speed abruptly changes?

    You got a laugh out of me, John. In that link you provided, you say (in bold) I wouldn't expect it to be much of an effect Now I could say that physics is unaffected by expectations, but how would that serve the discussion? The correct takeaway for me is to know that you agreed with me, (or that I agreed with you, since you created that post 10+ years ago). A small effect continuing for a long time can have a large outcome. Just because the rate of turn is small doesn't mean that a large turn won't be achieved after several minutes.

    Sometimes your turn of phrase is a little oddly antagonistic. "Physics is unaffected by feelings" sounds like an attack on what Seth wrote. He could have written, "I don't know whether..." and you could have written, "But physics knows!" Yet we're kind of on the same page, agreeing that there should be an effect based on our understanding of the physics... but we're not sure how much. Others may have different opinions on the size of the effect, based on their observations. This was all discussed at great length in the thread to which I provided a link in post #9 of this thread.

    Physics is unaffected by feelings. Since no-one has made a measurement of the magnitude of the effect, no-one knows. What we DO know is that Newton's 1st Law says there will be some effect.

    A canopy most certainly DOES know when it moves from a block of air moving at one speed to a block of air at a lower altitude moving at a different speed.

    The assumption that the canopy is flying in a homogeneously moving airmass is a convenient fiction. In reality the wind velocity is different at different altitudes, introducing a discernible directionality into the system and a descending canopy will respond to this.
