CNv Discussion / Re: CNv Task - What Observation Zones Are Used?
« Last post by nallison on October 05, 2020, 09:39:44 PM »
Hi Evan,

Thank you for your helpful reply. 

I now understand that CNv turn point OZs are a combination of both the 500 m radius cylinder and the 90 degree sector, a.k.a. the Thistle.

I did see this in the ClearNav forum topic "FAI badge and record turnpoints READ ME" but wasn't sure if it also applied to the Variometer.

<snip> ClearNav combines these Observation Zones into an "FAI thistle" which shows both the photo sector and the 500m radius cylinder.  As soon as you enter either of these observation zones, CN will update the "Destination" box to the next objective in your task.

Thank you,
Neil

You're correct.  At present only FAI specification start & finish lines (1 km) and turn point sectors (5mm radius barrel, 90 degree sector) are supported.

Integration with Other Devices (Flarm & Vario) / Re: Flam Traffic on CNII

My opinion:  Relative altitude is far more useful than climb rate.  Rex knows all about it :-).  I do know we have a software engineer looking over some possibilities for further product development.  I have no info on specifics or timeline.

CN2 is great at plotting target locations and transmitting collision warnings.  Various small stand alone devices are better for details, such as relative altitude, climb rate, distance.  I have an LXNav Flarmview 57 in my panel, which does a pretty good job of providing the details, as long as your vision can cope with the very small fonts.

Quite a few pilots feel that the relative altitude of Flarm targets is one of the more important bits of information, they would want to see on the ClearNavII display. Do you think there is any chance the ClearNav folks would consider bringing it back, in future versions? Perhaps even having this user-configurable, so every user can check box in the settings, what data of Flarm targets he wants to see on his display? (I.e. contest ID, relative altitude, rate of climb).

Hi,

Please point me to the info that describes the Observation Zones used when entering tasks into the CNv XC as, I'm sorry, I've not found it.

I'm starting to fly a club glider that has a CNv XC with a CNvS.  Before I go to our local regional contest, I'd like to be sure I understand what type of Start, TP and Finish OZ the CNv uses when I enter a task.  I am guessing/presuming:
  • 1 km Start Line
  • 500m radius cylinder for TP
  • 1 km Finish Line
From what I've read so far I think that the OZ size and type are not configurable for the CNv?

Thank you for any guidance you can offer.

Kind regards
Neil

The relative altitude number was replaced with the chevron scheme about 2016.

The USB drive needs to be FAT32.  I've had good luck with SanDisk Cruzer USB drives in CN2.  Some other (mostly unbranded) USB drives simply will not work. 

If that doesn't work, it's likely time to call Williams Soaring.

The CN vario (actually ADC) does not use a folder structure like the ClearNav II moving map.  The CNv updater and desired files must reside in the top level of the USB device.  It is recommended to use one USB stick for updating CNII with the proper folder structure and a separate one for the CNv ADC.

Customer Support / No boot on USB port
« Last post by MarcDD on September 19, 2020, 02:11:28 AM »
Hello,
we've quite a complete CNVII installation, including both CNV & variometer.
I'd try to update airspaces, using the USB stick procedure.
I used a formatted stick, with the file tree and exe files, downloaded from ClearNav site.

The device never booted on the stick.

I tried with Fat 32 and NFTS USB sticks... no way.

Our installation shows a "2 boxes" organisation :
- CNVII associated to the front screen,
- an additional device (same format) is coupled at the rear,
- the front port for USB is linked with the rear box.

Can you help me solving that issue ?

Thank you very much

Marc
