Using signals available into an Enhanced Ground Proximity Warning System (EGPWS), approach monitor systems and methods compare approach speed, approach angle and amount of tailwind/crosswind to the pre-selected envelopes. When the aircraft approach speed, approach angle, or tailwind/crosswind is greater than the pre-defined envelope, the approach monitor system generates an aural/visual advisory indicating the violation. The envelope is set as a function of "height above runway elevation".
