- The page says the comparison uses the same 162 starts for both versions, across three runway ends with 54 starts each.
Field notes
The page separates navigation performance from landing performance, reporting position estimates at the approach start before discussing touchdown results. Its comparison retains the earlier version’s figures rather than replacing them; it also warns that the available flight clip comes from a wider campaign and shows that earlier version, not the tests summarized here.
