The Apollo GX automates your DME-Arc procedure. As you near the start of the DME-Arc rather than a typical arrival alert, you are prompted that the next leg is a DME-Arc and that you may use Arc Assist.
The desired track shown on an Arc Assist page is relative to the arc, not to the flight plan legs. The DME-Arc is always perpendicular to the present radial and it shows the desired track at the current radial if the aircraft was on the arc. It is the desired no-wind heading if established on the arc.

Approach Basics (GX50/60) RAIM RAIM stands for Receiver Autonomous Integrity Monitor. It is a way a GPS receiver can verify when the signals it is receiving from one or more of the satellites are useable. It does this by using more satellites than are required for a position solution.

What does it mean when I get a “RAIM not available” message? If RAIM is not available, your Apollo GX may be capable of continuing to provide good accurate IFR navigation. What you have lost is the ability to tell if a satellite is sending bad data.
Page 222
RAIM becomes available again. This can be accomplished by cross-checking your GPS position against that of other navigation instruments. Even during times of no RAIM, if your Apollo GPS determines that it cannot provide an accurate position due to poor satellite availability or geometry, it will flag the navigation display as invalid.

Manual Flight You are flying a section of an active flight plan from Plan Leg SLE to BTG to OLM. As you approach the Portland Selection area, you are given Radar vectors to the West of your Example course. ATC then tells you: “Fly heading 360, resume own navigation, intercept V287 to OLM, then as filed...”...

Unnamed bearing/distance waypoints: Idents for unnamed turn points, intersections, or bearing/distance waypoints (other than VHF navaid distance/bearing), that are not coincidental with named waypoints, are constructed by using the ident of the nearest navaid together with the distance (rounded to whole miles). If the distance is less than 100 nm, the distance follows the navaid ident.
