Why no Yaw in Telemetry?

Posted by Stevod on June 14, 2017 at 6:59am

Hi guys,

As Pitch, Roll and Yaw are three basic parameters that every pilots get taught about at flight school, I'm surprised it doesn't appear in any of the telemetry readings from the EMU-COPTER. Is there something different about drones that means it is less relevant than for fixed wing aircraft?

I have found the heading and course telemetry, which I assume are the actual compass bearing of the aircraft, and the course that has been laid in, respectively (as the two may be different e.g. due to spline way-points causing a different heading from the plotted, straight line course). Am I correct?

Thanks.

David

    In a multi-rotor, Roll is similar to Yaw as an indication of compensation

    Hi David, you are right. UgCS shows only heading and course in telemetry. Nobody asked us to show yaw.

    For copters yaw isn't vital parameter parameter at all because it can fly in any directions. For fixed wing drones yaw is controlled by autopilot to compensate side wind. I don't have much experience with fixed wing drones but it seems that it's not very important to see numeric yaw value - you can always estimate how big is yaw using arrow indicators of heading and course.
