@OK465;

The A/P pb can then be engaged, even though ACTUAL speed (CAS) is below ACTUAL VLS. VLS is neither displayed nor indicated on the FMGEC landing phase PERF page.

Agreed!

But there is one more set of variables (includes CAS > VLS) to be confirmed before the A/P will actually engage, and that is not met. The logic presented by A33Zab clearly shows that with regard to the A/P the CAS/Pitch/Roll condition is the final inhibition - irrespective of FMGEC, other than when Pitch Angle Protection is active in Normal Law.
