just read that again Nick....where is the requirement to check one engine landing performance ? What you refer to defines the maximum distance to the alternate. Nothing else and they should be set numbers in your companies OPS SPEC that goes into your PART A. The requirement for a take off alternate is simply weather and nothing to do with the reason for the return. Instead of just reading regulations think about the reasoning behind them. An engine failure requires land at the nearest suitable airport which is why distance is important.
