None, the Boeing Checklist does not have it.
Our outfit put one in specifically for (and only for) RNP AR operations to cover a single GPS failure due to the complexity of the RNP AR we fly and the size of the hills on approach and the length of time we are below area MSA.
The legacy checklist from the 200 series did have a recall check in the approach checklist but I am unsure if it was Boeing or Customer initiative.
