Figure 4-3: Mounting cutout sensor unit
The sensor unit needs to be aligned with the aircraft axes by the following margins:
-
Yaw axis: +-1°. Misalignment leads to inaccurate wind indication during longer straight flight
segments without moderate changes in airspeed and heading.
-
Roll axis: +- 3°. Misalignment leads to permanent offset of the roll angle indicated by the artificial
horizon (AHRS), and potentially falsifies wind indication during longer straight flight segments.
-
Pitch axis: +-7°. Alignment can be adjusted and chosen within a relatively wide-angle range with
no noticeable effect on wind indication. The mounting pitch attitude of the sensor unit will be
indicated as
“
zero pitch
”
on the artificial horizon (AHRS).
The sensor unit must always be mounted so that the labeled side of the device is
“
up
”
. A vertical
mounting is not possible.
The sensor unit can be mounted in four different yaw orientations, indicated as A, B, C, D on the top
side of the sensor unit. If the sensor unit is installed with direction A pointing in the DOF (direction of
flight) no further action is required upon installation. If the sensor unit is installed in the directions of
B/C/D, the DOF must be set in the menu once after installation, as explained in chapter 6.3: Setup
Menu
under “Align DOF”.
Three-dimensional CAD-models of the units and the cutout of the display unit are available at the RS
Flight Systems website.
As waste heat is dissipated via free convection, leave at least a 5 mm gap from the aluminum surfaces
to any other object. Forced cooling is not necessary.
The installation must be in accordance with the appropriate guidelines approved by the respective
aviation authority. The person installing the device is responsible for compliance with all applicable
legislation.
