Flighttest of the new LXNAV HAWK wind and variometer indicator

Could someone please confirm or deny that this is all possible due to inertial sensor input and massive computation?

I have one. But my algorithm is better, quicker and I spend less time looking at my dash in a fat fingered attempt at experience and currency instead of another instrument feigning better tech.. just go fly and figure out how to thermal.

I see that the central part of the vario displau is now used to display these large wind arrays.
But what about the integrated vario and netto data usually displayed there ? These data are absolutely necessary to my opinion.

Nice explanation. Thanks. What is the difference, in terms of measured wind, between HAWK and the "standard" wind calculation of S100? Since a while now, S100 introduced a third page where we can see the 2 large wind arrows.

Please say the hawk option isn’t a subscription

Hello Rudi, I already have the LX - AHRS installed, what happens when Hawk is installed on top? The LX AHRS is it still active, is there a second menu icon for the Hawk AHRS or is the Hawk based not only on the Hardware but also on the LX-Nav AHRS-software ? And if it is based on it, why to pay twice for the AHRS function ?

I have to test it, but it seems to be interesting

Hi Rudi,
If building a new panel from scratch is there any point having a mechanical vario and TE tube if HAWK is installed?

I tried the DEMO yesterday, and found out a very large difference in vario average in the first 2 circles, then in steady climb the difference was little: 4.5 versus 2.5 m/s at the beginning of the thermal (very turbolent) and then 3 versus 2.8 m/s.
About the wind, since you can not see the HAWK and NOT-HAWK wind at the same moment, you can not compare, but since it was a windy day, I could appreciate the quick change in calculated wind, and it was really correct! you can see it at best when flying on a ridge with multiple orthogonal ridges decreasing into the valley, and the wind is not really 90° with the main ridge. The climb was where the HAWK expected, this means the wind was ok.

I have to try it better, and understand the parameters to be set,

a pity for the price, will not buy it this year for sure.

Thanks for the video. I just installed the demo version and was wondering how to interpret the indications. Now I have a better idea. Cheers

Flachland-Flug 4,5h mit HAWK-Demo-Lizenz: Einstellungen: Vario und Sollfahrt Anzeige und Audio : HAWK. Ich habe sehr große Unterschiede zwischen dem roten und blauen (HAWK) Zeiger auf dem V8 gesehen. Mein Fazit: HAWK hat mich kein einziges Mal bei der Thermiksuche in die Irre geführt. Dies wäre öfter der Fall gewesen, hätte ich dem üblichen roten Vario-Zeiger vertraut. Für mich stellt das HAWK-Vario einen positiven Generationssprung dar. Offene Frage für die HAWK-Demo-Lizenz: AHRS ließ sich nicht kalibrieren.....Ist dies bewusst so, bei der HAWK-Demo-Lizenz?

Glider pilots have never had accurate real time wind direction and speed. So now we need to figure out how to use that information. The manual for the Anemoi Wind-Indication-System (similar to Hawk Wind) says that real time wind information can be used to detect/confirm the core center of a thermal. And also for finding lift in Rotor under Wave. I think wind direction might also suggest whether to turn left or right to thermal when lift/sink causes an uncommanded roll. Might also be good for finding the small section of a convoluted ridge line that is producing lift. I've found that in mountains/hills, the wind direction changes depending on your location relative to the terrain. Might also good for finding convergence lift, especially on blue sky days (no clouds).

I like this instrument because it requires a new skill to interpret and exploit. Maybe there are new soaring techniques to discover.

WRT Hawk, I wonder if LXNav will figure out how to use sound to convey important wind information. I could live without the audible vario sound. I mostly use the averager on my S7 and body sensations to thermal. In gusty conditions, the beeping is not great because of the lag and I'm not sure that I need it.

It will be easier to read the wind info at a glance once Up=heading on the display. One thing I like about the Anemoi instrument is that it's small size allows it to be positioned near the top edge of the instrument panel, make it easier to read at a glance.

If the Hawk responds more quickly than the TEK vario, does that mean it has "no" lag and corresponds exactly to "seat of the pants" or "feel", or is it rather "closer" to instantaneous response? My last coaching encouraged me to respond to "feel" and not the variometer indication, and made a great difference to my flying. So, will the Hawk give me an improvement, in your experience?

Watching the needles I see they are always very close to each other. Probably not enough to make any difference.

I flew with HAWK wind in weak thermal conditions a few days ago. Similar thoughts to Rudi regarding the TEK vario lagging behind HAWK.

Danke! Gut gemacht und sehr hilfreich!

Servus Rudi,
da du schon über Erfahrung mit dem HAWK verfügst möchte ich folgende Frage stellen:
Das Interessanteste wäre für mich die Relation des aktuellen Windes zur Flugrichtung. Kann man ein Flugzeugsymbol am Bildschirm darstellen und dann sehen aus welcher Richtung in Relation zum Flugzeug der Wind aktuell kommt?
Liebe Grüße
Manfred

Why would you still want to see the "conventional" vario indicater when you have upgraded to the superior one? It would confuse the hell out of me.

The license fee is BTW rather high. LX Nav is basically saying to its customers that their already expensive system came with underperforming software but for another 1000 euro you can finally have the full monty. I would be hesitant to spend this amount of money. And will the hawk software be included on new LX units or is still optional?

Hello, Thanks for the videos. I have a S80 and unfortunately this option is not available for it at the moment. Is it possible to display the wind arrow relative to the glider trajectory? It seems S100 displays the estimated wind direction relative to the north which is less practical...

Hallo Rudi, besten Dank für deine schnelle Antwort. Ich möchte noch eine Frage hinterher schieben: Bei Motorseglern, insbesondere bei Eigenstartern, besteht während des Motorsteigflugs keine genaue Vario-Anzeige. Deswegen nutzen einige Modelle eine "Hilfs-Konstruktion", in dem eine Umschaltung Vario auf den statischen Druck durchgeführt wird. In meinem jetzigen Flieger gibt es diese "Hilfs-Konstruktion" nicht. Nun meine Frage: Berechnet HAWK für den Motorsteigflug die korrekten Steigwerte oder sind die Steigwerte im Motorflug auch sehr stark gestört durch die Propellerwirbel?

Können die HAWK-Wind-Vektoren auch "Track-Oben" dargestellt werden?

How does this differ substantially from what has been available with the Air Glide vario for nearly a decade? Also, are you able to select either the TEK or the "real-time" response for your audio inputs? Thanks for your review!

A lot of airliner features now in your silent 2 electro! Amazing how far technology has come. Especially considering how small that instrument is….

Danke Rudi, für das nochmalige zeigen nach der schon sehr ausführlichen "Late Nicht Soaring" Bericht. Das ist wirklich ein Schritt in eine neue Generation und Entwicklung:) Aber ich bin mir selber noch unschlüssig über die Gebühr 1200€ für die Freischaltung...wobei ich dennoch die Entwicklung von Prof. Meyr sehr Wertschöpfe!

Very good my friend.
I wish you all the best.
Really it's amazing.

? Encourages a lot of head in cockpit?

Schön gemacht und gut erklärt! Nach der Präsentation des Erfinders am Segelfliegertag in LOGO letzten Herbst ein super Beispiel, wie das dann in der Praxis aussieht!

Ironically I just flew with the S100 and HAWK enabled for the first time today. It was incredible. In thermal and convergence flying: you can find lift lines and simply fly STRAIGHT INTO THE WIND! Then you stay on the lift line until it runs out. Absolutely incredible! Today I removed my TEK probe, and it will be stored in the trailer until the day the glider is sold. I'll never use it again!

Excellent! Well done!

AHARS is included, if you already have AHARS do you get a discount on the HAWK price?

Hi, gute Ergänzung zum Late Night Soaring topic von gestern, danke für die anschauliche Darstellung :-)

haha cool aber ich versteh noch nicht ganz wie jetzt alles tatsächlich gemessen wird, man braucht ja den groundspeed oder nicht?

Cool erklärt - DANKESCHÖN 😊
