  • Page 61 HAWK system was developed by Prof. Heinrich Meyr and Peng Huang in cooperation with LXNAV. It features a completely new approach towards measuring the three-dimensional wind vector. A conventional vario measures the vertical movement of the glider (vario) based on an energy conservation principle.
  • Page 62 Rev #1 Version I9.33/S9.34 January 2025 Wind field estimated by HAWK. spatial coordinates (x, y, z) and the time t. The wind field is described by very complex mathematical equations. For our purposes, it is sufficient to use a greatly simplified model. We assume that the wind vector comprises two elements: a slowly varying component and a rapidly varying random disturbance.
  • Page 63 Rev #1 Version I9.33/S9.34 January 2025 In picture above, the variometer shows a value of 3m/s. This value corresponds to the slowly changing part of the model. The rapidly changing, random part corresponds to the fluctuations of the pointer around the mean. The pointer fluctuations are Gauss­ distributed, see right picture above.
  • Page 64 Rev #1 Version I9.33/S9.34 January 2025 Let us choose a value wind variance = 0.1, which looks plausible. Qualitatively, if we select a very small value of wind variance = 0.001 the algorithm will average the estimate since it considers large deviations ∆d as highly unlikely and suppresses them. We next consider the opposite case and select a much larger value wind variance = 0.5.

If we fly with a large side slip, the glider‘s climb rate is smaller than flying with zero sideslip in the same thermal. The Netto TEK and the Relative TEK vario are derived quantities by adding fixed constants to Vario TEK.
  • Page 66 Rev #1 Version I9.33/S9.34 January 2025 Segment A: Sideslip angle and Netto difference. In a nutshell: The agreement between TEK and HAWK vario during stationary circling of the glider is particularly good. This changes completely when we analyse segment B and C. Picture below shows two segments B and C of the same flight of the ASG 32.
  • Page 67 Rev #1 Version I9.33/S9.34 January 2025 In segment C the sideslip angle is decreased to ­6.2 degrees. The string is slightly pointing outside, as usual. We first analyse segment B where the sideslip angle is ­12 degrees. The glider climbs with 1.8 m/s (2nd row in Table 1).

If the unit is installed in the glider with more offset, HAWK algorithm might not work properly. If installed device is not perfectly aligned with glider longitudinal axis it is essential to do a pitch alignment, which can be done in Setup>Hardware>AHRS menu.
