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?

Or, in the event the situation is as described - when you press make approach - have an initial pop up box which says

‘Do you want to make approach at
A destination airfield X
B alternate airfield Y’

I agree the system shouldn’t force you and lock you out of what you want to do, unless it has been manually instructed somehow that you’re diverting.
