Two days ago, Brian in the US reported to me that the “Heading Bug” on the HSI gauge developed for Just Flight’s Arrow III, Turbo Arrow III and Arrow IV is malfunctioning.

The “Heading Bug” doesn’t change accordingly when the “Heading Bug Knob” is turned. It only works when the autopilot is engaged with a flight plan and an activated approach. If the flight plan or the approach is removed, the “Heading Bug” will stop working instantly. The faulty situation applies to the HDG gauge as well.

I then checked and confirmed the case is valid, but the error is actually caused by the Arrows and not by my gauges.

The gauges and their “Heading Bugs” work as usual on Just Flight’s Warrior II and all other aircraft.

After further investigation, I found a similar case was in fact reported to Just Flight earlier in February by another user, and the error was later fixed.

Frankly speaking, I didn’t aware of the case at all since the bug didn’t come from my gauges.

Anyway, the issue is back with the Arrow’s latest version.

I have reported the issue to Just Flight already and their technical support has responded and is working on it now.

An update or a hotfix, I believe, should be coming soon.
