SD 3.8.2.72
iPad 4 mini

Situation: 3 Airports A, B, and C in one line.

Planned route is A to C with B set as alternate.

When overflying B, SD switches unwanted to approach for airport B and I had no chance to switch to approach for airport C!

Approach tools was not only useless in this approach, it also led to high workload when I tried to solve this unexpected situation without success.

How can I set the approach tools to the airport I want to land?

That's pretty much exactly how it works already.

I think you are describing an edge case where you're overflying your alternate in pretty much a direct line before you get to your destination? What is the problem with removing your alternate when you know you're going to your destination, at which point SkyDemon would offer you all the normal approach tools? ‌‌

OK, it's a workaround!
Nevertheless it would be advantageous if the alternate remains in the pilot log until landing at the destination is assured...

I don't know if it was an edge case.
Airport B was LKCB and airport C was LKKV.
Is far as I remember, the wrong LKCB approach was persistent active until I reached VRP B of LKKV.
