Operand meaning

[Sibre3]

I got a question about operand function- Is Controlling Position. It would seem to correspond to NAV_CTL_POS. But I couldn't work out the limits of that condition.
I want the boolean state to change when the airplane is holding position or loitering in all navigation modes. Example. Loiter, RTH loiter above the home location, fixed wing landing and RTH spiral climb.
Will this function accomplish the requirement?

Yes, it corresponds to NAV_CTL_POS. Which means INAV is controlling the position.

That would be true for position mode, cruise, course, RTH, waypoint, and geozone.

It sounds like pretty much you want to know if the target position is approximately equal to the current position.
In other words, the current distance to the target location. I'm not sure you can do that with the programming framework.

That was the plan. But not possible from what you're saying.

Yeah probably not. Not directly anyway.

So maybe time to go up a level or two - what are you trying to accomplish by this?

You could do similar indirectly - checking if it's in loiter mode is straightforward, then check if it's in RTH and near home. Maybe check if the distance to home hasn't changed much in the last few seconds.
