'Energy Lines'

[Ian Molesworth]

Hmmm. 

Password 141000 is one digit too many.

The LXnav Installation manual link on the downloads page links to a document titled 'V8x User manual' which has installation details and very little else.

There doesnt actually appear to be a user manual that i can find.

Is the 'energy lines' post on FB a con? 

No documentation about for it and a few questions posted without answers!

The yellow arrow is alive and well on my S10

Great!

Can't get any sense out of my V8. And without a manual its a bit challenging.

Will this work on the S80?
And what is it supposed to do?

Yes, it will work on an S80.  In uses the average and current wind vectors to calculate the difference between the two.  In other rods put the two wind arrows tail-to-tail, and draw a line from the average head to the current heat.  That is the most likely direction of local lift, so in an initial climb turn in that direction.  On cruise near convergence, deviate in that direction.  It does NOT require Hawk.  Pretty ingenuous IMHO.  I just wonder how long it could have been hiding in there, used by some, but not others.

[cdeerinck]

The code is 141000 in the V8x.  Not sure about the others.  Ask LX support then report back here.  It’s free, not for sale.

Cumulus has the best info…

The code 141000 is one digit too long.  Enter 14100.  If you're like me, you will have trouble figuring out how to advance the cursor in the password page of the V8.  Thanks to Uros I can tell you that a long press of the bottom button will advance the cursor.  I flew with it yesterday.  As yet, I haven't found it to do much, but it's only one flight.  Having to display the wind page on the vario to see it is a really bad setup for me.  I use my vario as my chief altitude indication and want to be able to see the data blocks I have displayed there both in cruise and climb.  If had two V8s I could keep one on the wind page, but I don't.  I asked Uros if they plan to display it on the 9070 screen as well, but got no response.  When I did look at it yesterday I had the yellow arrow head nervously rotating and an occasional arrow shaft that would appear and then immediately disappear.  I also found that my climb audio had been kicked back over to vario instead of Hawk and that Hawk had been reselected for one of the factors that determines average wind.  I have been using Hawk audio in climb happily for a while now and it is my preferred setting.  I deselect Hawk as an average wind parameter because when it is selected average and instantaneous wind are almost always exactly the same.  It's possible I'm being foolish here, but I want to see a difference between average and instantaneous wind to help identify small scale convergence.  With it set that way, I have seen differences in readout between average and instantaneous wind in areas of convergence around the coastline and Lake Okeechobee.  I had updated my profile in the 9070 the morning that I enabled the yellow arc, so it is possible that the settings changes were caused by the profile change, but you might want to check your settings after entering the password.

Sloppy from LXNav.

I posted about the long password .... no answer.

And the lack of manual with homefully the means to advance the cursor ...... no answer.

And still no official text on what you are looking at and how to use the info.

Ian - And yet you have  all the answers you need here, from various people posting:

1) Password, drop the last 0

2) Advancing the digit, long press on the down arrow

3) Official documentation: I posted what Paul posted on Cumulus, showing an excerpt from the manual.

I am perfectly fine with LX focusing their efforts on development, instead of spoon-feeding every customer support issue.

I guess it depends on if you want a solution, or if you prefer to just complain.

We all took the extra time to post here to help people out, and help relieve the effort required by LX.

Also, not lost on me is that they aren't selling this, but rather gave it out for free.

Hi,

I just hosted a very nice HAWK Webinar and Toni and Uros from LXNAV chatted a little before the meeting about the new yellow arrow for energy lines.  

There were 2 major corrections:

 - The new feature requires HAWK, so it works only on S10, S100, V8, and V80 varios or systems with HAWK enabled.  It does not work on S8 and S80 varios because they don't support HAWK.

 - The feature has been in the software/firmware for a while, but LXNAV recommends updating to the latest released or beta version.  There will be a checkbox to use to enable the feature in a future firmware version.  For now, enter password 14100.

Best Regards,

I have flown with the yellow arrow two days now.  I wonder if something isn't right with my setup.  I had to reenter the password today to enable it, which seemed odd. In flight it doesn't do anything.  The yellow arrow head twitches nervously around in circles, occasionally and very briefly sprouting a tail which disappears as quickly as it appeared.  It never points at anything.  I tried adjusting the Hawk average wind settings, but found no improvement.  It's a cool idea if it works.  But there has to be a way to display it on another screen.

What were your grey and blue Hawk wind arrows showing?  If the instant and average winds are not diverging significantly then the yellow arrow won't have anything to indicate.  As far as I can see, in graphical tems the yellow arrow just connects the tips of the 2 wind arrows so in that case one can imagine the yellow arrow would flicker off and on with minor changes in the instantaneous wind.   I haven't flown with it yet but it sounds as if there ought to be some damping applied to the yellow arrow

I entered the password in my V80, got a confirmation that an Easter egg was enabled, but nothing happen. When I change modes in my V80 to the wind screen I get a message that wind is not available. I understood this feature does not require hawk, which I don’t have, as my hardware is 3rd gen. Perhaps it only works on 4th gen?

The Energy Lines feature does require HAWK.  You can see details here:

Hi Ramy,

I had the same problem. The solution for me was, the feature worked when I am in the air. One have to enter the password every time the V4 powers up again. So if I want to use the feature, I enter the code. Sometimes I forget on the ground and I do it airborne. So far it works ok for me. 

Cheers

Hi,

The new energy lines feature only works with HAWK.  HAWK is required.

At this time, the feature must be enabled using the 14100 password after every power-up.  It will be a setup menu setting in a future version.  It will then remain on though a power-down.

Best Regards,

My S100 showed HAWK's yellow energy line pointer yesterday, but I did not enter a password.  I can't recall if I entered a password when installing the update, but that was weeks ago.  I certainly did not enter a password yesterday.

Hi David,

I'm sure you're correct.  That being the case, it must be only the V8 and LX90x0 systems that don't yet have the energy lines feature working through a power-down.  A customer noticed the situation a few days ago and LXNAV confirmed that it needed to be enabled after every power-up.

I've flown a couple of long flights now with the yellow arrow. I've yet to see anything useful.  One problem is that the yellow arrow is always too short to even tell which way it is pointing, even as thermals are approached.  If they put a 3X multiplier on the arrow value, I might be able to see what's going on.  Another problem is that it's almost impossible to see the yellow arrow when white background is selected.  If you switch to black background, you can see the yellow arrow but then it becomes hard to see the other arrows that are dark colors. Maybe they ought to give the yellow arrow a black outline or something.

Yep,  I only just found out why I never seen the yellow arrow on my V8/9070 - it never crossed my mind that it would have to be enabled every flight

[David S]

Having now upgraded my S100 to software version 9.52, I no longer have the yellow arrow for energy lines.  Entering the password did not help.  The password page displayed the message "Easter egg enabled" but still no yellow line.

David,

I got the same message, haven’t had a chance to fly, planning tomorrow.

[Glenn Betzoldt]

I got the same thing?

[Adam Sayer]

I found the Energy Lines is now an tick box option in the Menu, Display -> Thermal (I think)

It was unchecked by default on the 9.52 firmware

At the bottom of the V8 INDICATOR page there is a check box for wind energy arrow.
