HAWK Vario, Wind and AHRS - Enable for LX80x0, LX90x0, S10, or S100   

Features:

• HAWK’s blue vario pointer is fast and closely matches the lift you feel in the seat of your pants.  
• Better than any other vario - ever!
• Ignore fake thermals caused by gusts
• How many times has this happened to you:
• You’re cruising. 
• You feel a bump.
• The red Total Energy vario pointer goes up.
• You stop to circle and find no usable lift. 
• It’s not a thermal.  It’s a gust.
•  With HAWK:
• The blue HAWK vario pointer remains flat.  HAWK knows it’s a gust!
• Never again waste time stopping to try a “thermal” that is really a bump from a gust.
• Greatly increase your cross-country speed (worth every penny of price)
• Know exactly what the wind is doing in real-time
• HAWK software uses accelerometers and GPS for:
• Fast vario which ignores horizontal gusts
• Fast wind data for optimizing flight in convergence and wave
• AHRS
  

The HAWK and AHRS sensors are built-into all V9, V8, V80, S10 and S100 varios. To use the HAWK Wind and AHRS functionality it is necessary to purchase this software enable key. The artificial horizon and airspeed and altitude items can be setup to display on any page on the LX80X0 or LX90X0 display using the LXStyler program - or using the controls on the flight computer. The artificial horizon also displays on the V8 and V80 vario's display and on the S10 and S100 vario's display.

HAWK Compatibility: 

• S10 and S100
  HAWK will run on all S10 and S100 units
• LX80x0 and LX90x0
  HAWK will run on all devices from 4th Generation LX80x0 or LX90x0 onwards and V8/V80 vario only.  The easiest way to check for compatibility with HAWK is to install the latest version (currently 8.04b) of the software and go to Setup->About.
  

Details are available in the LX80x0 or LX90x0 or S10, or S100 manual which is available here.

"Are you dreaming about having a real time wind indication in your glider? Do you feel sometimes in the mountainous regions or areas of convergence that the wind suddenly changes?”

Get real-time wind with HAWK

Real-time wind indication – 3D wind. HAWK option enables instantaneous wind readings on all 3 axes.

Measurement
HAWK uses sensor fusion and advanced digital signal processing to estimate the air mass movement.

3-dimensional wind triangle
HAWK applies an “extended Kalman filter” (EKF) algorithm that jointly estimates all three dimensions of the air mass movement.

Instant results
EKF estimates the wind direction and velocity instantaneously (horizontal and vertical). No more waiting!

No compensation, no compromise
No compensation needed, since it uses no law of energy conservation. More accurate netto vario readings independent of glider speed.

No false thermals due to wind gusts = No more “stick” lift.

Wind indication
Wind screen enables you to view the instantaneous wind on the blue arrow and the wind average on the white arrow .

2 needle vario
A red and blue vario needles at the same time. Red shows the value of computations of the TEK while light blue shows the value of the EKF.

AHRS
The results of the attitude estimate of the EKF can also be displayed as an artificial horizon.

HAWK Setup Tips

 IMPORTANT: For HAWK to work well, it is very important to calibrate/align the AHRS.  With the wings level and the tail raised to flight attitude:

• LX80x0 or LX90x0:
• Setup, Hardware, AHRS, and select "Level".
• S10 or S100:
• Setup, Hardware, AHRS, and select "Level", then press the lower-right button to select "Yes".
  

HAWK Setup for LX80x0 and LX90x0
