<![CDATA[PROF mode in climb/Unable to maintain speed target]]>Hello everyone,

On my first flight now, close to maximum weight in the F100. During climb in the PROF mode, the aircraft seems to have quite a hard time keeping the speed constant. It will constantly fluctuate between +-10 knots, and the VS will deviate quite some.

Is this a quirk of the aircraft and its systems or is it something else i have not considered? 🙂

If you see that behaviour again, could I kindly ask you to raise a support ticket for this with Just Flight Support at the following link: https://www.justflight.com/support

The F70 & F100 Professional are complex products, so in order to give our support team the best chance at offering speedy assistance, could you please include any screenshots/videos of the behaviour with your ticket, as well as attaching the log file?
