Wind Vector

Always stay on top of your winds aloft with this small feature that hides next to the altimeter.   

What is it?

The wind vector is an estimate of the winds that the aircraft is flying through. It’s located to the right of the altimeter baro setting and is calculated using GPS ground track, ground speed, and heading and true airspeed data provided by the AHRS.  

It consists of two main parts- a vector arrow with velocity and direction, and a headwind/crosswind component. At its simplest, it is an arrow with a velocity number next to it. The wind blows from tail to head. The velocity is given in the speed/distance units chosen for the EFIS system. In addition to the vector arrow, a magnetic compass direction can also be displayed.  

To turn on the wind vector:

  1. Press MORE > Set Menu > Primary Flight Display
  2. Scroll to Wind Indicator Mode. Choose  OFF, Vector and Digital Speed (shown at right, top), or Vector and Digital Speed/Direction (adds magnetic wind direction to the above display, shown at right, center).

Headwind/Crosswind Component

The headwind/crosswind component gives headwind (H) or tailwind (T) first and left (L) or right (R) crosswind second. To turn on head/crosswind component:

  1. Press MORE > Set Menu > Primary Flight Display
  2. Scroll to Digital Head/Crosswind Display and turn it ON or OFF.

NOTE: If insufficient data exists for calculation of winds, the wind information is not displayed. Accurate winds require accurate magnetic heading and airspeed data, which are enhanced by performing proper calibration of magnetometer and pitot/static systems as detailed in the HXr Installation Manual (also the HX User Manual, Rev. C, Section 9).

The Flight Path Marker is slightly right of the aircraft centerline because of the crosswind from the left, indicated by the Wind Vector.
