Press the EDIT button and start editing the value. 6.1.1.1 QNH* Using this feature, it is possible to offset the altitude datum which could have changed due to pressure changes during the flight.
Page 37 Rev #56 Version 9 May 2024 Safety Mc When this setting is used, final glide is calculated using independent Safety Mc value. This value can be set in this menu or in quick access menu like Mc for speed to fly. All final glide calculations will be calculated by this Safety Mc value.
Page 38: Altitude Source
Rev #56 Version 9 May 2024 Safety Mc-offset Sometimes it is convenient to have some additional safety, which depends on distance to target. Therefore, we have introduced Safety Mc-offset. This value is automatically added to your selected MacCready value and then sum of Mc and Mc-offset is used to calculate final glides, whereas speed to fly is calculated by Mc only.
Page 39: Soaring Start
Rev #56 Version 9 May 2024  MacCready uses the Polar data and MacCready setting to calculate speed to fly and climb rate.  Vario uses the last four thermals average to compute climb rate and uses this value to calculate speed to fly.

Page 81: Altitude Warning
Rev #56 Version 9 May 2024 Airspace warnings are the most complex ones. An airspace warning is activated by two triggers; the first warning (orange) will be given when a projected position of flight for period, which is defined in the Time item, is computed to cross an airspace zone. The second warning (red) will be raised when a projected position of flight is computed to cross an airspace zone and the glider is already in the buffer zone in the vertical or horizontal directions.
Page 82 Rev #56 Version 9 May 2024 If the projected altitude is greater than the set altitude, an altitude warning will be raised. Altitude warnings will be raised in all modes and dialogues just as for airspace warnings. Altitude warnings can be dismissed for 1 minute, 5 minutes or disabled. Altitude warnings can be set for approaching from below a defined altitude or from above a defined altitude.

Rev #56 Version 9 May 2024 7 is entered twice for minimum weight. CG envelope will look like one on the picture above to the right. If you wish, you can also enter optimal range, which is not specified for Arcus M glider. 8.2 Glider speeds Glider speed should be read from flight manual or from place cards inside the glider.
Page 210 Rev #56 Version 9 May 2024 Remaining water will be calculated once DUMP button is pressed or if water switch is connected to the system. For Arcus M main tank capacity is 14 litres, fuel consumption is around 25l/h. Dump rates for water as stated in flight manual for Arcus M is 3.5minutes for full tanks, which give a rate around 60l/minute.
Page 211: Hawk
9.1 Introduction 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 212: Wind Model
Rev #56 Version 9 May 2024 9.2 Wind Model The HAWK requires a mathematical model of the three-dimensional wind vector. Figure below shows wind field estimated by HAWK. The wind vector d(x, y, z; t) depends on the three Wind field estimated by HAWK. Spatial coordinates (x, y, z) and the time t.
Page 213 Rev #56 Version 9 May 2024 For an intuitive understanding of the model, we limit ourselves to the vertical component. We are used to interpreting the rate of the variometer by the movements of the pointer. For this reason, we look at the increment over a time interval of 1 second. In picture above, the variometer shows a value of 3m/s.
Page 214: The Potential Climb Rate
Rev #56 Version 9 May 2024 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.
Page 215 Rev #56 Version 9 May 2024 During circling most pilots fly with the string slightly outside. The HAWK calculates the sideslip angle. The large majority of pilots fly with small sideslip angles of less than 4 degrees. Before we demonstrate the effect by an example, we recall some properties of the conventional TEK vario.
Page 216 Rev #56 Version 9 May 2024 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 217 Rev #56 Version 9 May 2024 We first analyse segment B where the sideslip angle is 12 degrees. The glider climbs with 1.8 m/s (2 row in Table 1). The vertical wind (Netto HAWK) equals 4.4 m/s. The Vertical TAS (sink rate) is estimated as 2.9m/s. Based on the vertical wind triangle, the summation of these two values equals 1.5 m/s.
Page 218: Dynamic Behaviour
HAWK system, a HAWK option must be purchased. Please contact your local dealer or LXNAV directly to get your HAWK option. Once you receive option file from us refer to Chapter 13.2 for installation procedure. HAWK system can also be tested free of charge for a period of 3 months. Please visit www.lxnav.com...
Page 219: Levelling Ahrs
Rev #56 Version 9 May 2024 9.7.4 Levelling AHRS It is absolutely necessary that the plane is aligned with the longitudinal axis defined in the manual of the glider. Any misalignment leads to systematic errors in the HAWK algorithm. HAWK algorithm can compensate ±10° of the pitch offset. If the unit is installed in the glider with more offset, HAWK algorithm might not work properly.
Page 220: Restarting Hawk
Rev #56 Version 9 May 2024 9.8 Restarting HAWK 9.8.1 Manual restarting HAWK can be restarted at any time. To ease restarting the procedure must be quick and simple. For this reason three restarting methods have been introduced in the top hierarchic level, see the screenshots below.
Page 221: Flying With The System
Rev #56 Version 9 May 2024 10 Flying With the System To get the best out of the system it is important that some preparation is done prior to take- off. Trying to configure the instrument or set a task while flying is very hazardous especially in a competition.

The system will always take the correct time as start time. If for some reason you miss the start message you may always start the task by pressing the START button.
Page 228: Maximum Start Speed And/Or Maximum Start Altitude
Rev #56 Version 9 May 2024 Character “B” will be displayed before the MacCready value which indicates that the final glide is in below altitude mode. The lower number shows the difference to the set altitude. Negative values mean altitudes below set altitude.
Page 229: Event Start Procedure
Rev #56 Version 9 May 2024 The arrival altitude to start is not based on MacCready, the glider nor the wind settings. It is calculated based on energy difference during flying straight. This gives a very precise estimate at what altitude you will arrive at the start. Speeding up will result in greater energy loss and the arrival altitude will decrease;...
