GRT Avionics

The waypoint markers were added to the HX a year or so ago and they are great. What are they called? (I call them 'lolipops')

They provide both lateral and vertical guidance to the next waypoint on a flight plan. What else can you tell me about how they work?

Is there any point at which they are not providing vertical guidance? How can I tell?

Is there documentation about how they operate or how they can/should be used?

Thanks.

I think GRT calls them balloons. The vertical guidance is not set by tbe flight plan, but by what you enter as the desired altitude on the HX. On the GRT home page, there is a new reference to using the flight path markers on the HXr. Much of that applies to the HX.

Opps, wrong word. "flight path marker" is the bulls eye that shows where you are headed. You want to put that on the balloon. I should have said, the latest pilots guide for the HXr is posted, and it has a section on the balloons, much of which applies to the HX. Use caution if you are using a balloon for an approach, the balloon is centered on the airport, not the missed approach point.
