Systems and methods directed to evaluating and enabling enhanced glide slope angles are provided. The method includes, in a control module, identifying a designated glide slope angle (D_GSA) based on a designated approach procedure; receiving and processing sensor data and navigation data; and, generating an adaptive glide slope angle (A_GSA) and an associated final capture altitude (FCA) based thereon. The method includes determining whether (a) an altitude constraint applies at the FCA, and determining whether (b) a level segment exists at the FCA. When (a) and (b) are concurrent, the method enables modification of the designated approach procedure with the A_GSA; and, the method prevents modification of the designated approach procedure with the A_GSA when there is no concurrence of (a) and (b).
