FLTA vs TAWS?

The Honeywell system has some shortcomings from my point of view, in particular the inability to tell it about airfields not it its database. Consequently every time I land at my airstrip I have to disable it - then remember to re-enable after takeoff. There are other locations I fly to with the same issue, and it's very disconcerting to get a "PULL UP!" call on final. The 440 apparently has the ability to enter user-defined waypoints in a manner that automatically suppresses the callouts within a radius.

So, my question is, if I were to remove the KGP560 TAWS and enable the 440's FLTA, what would I lose (other than a few pounds?)

There are 4 differences between the IFD FLTA and a KGP560 EGPWS:

1.  KGP560 is a certified TAWS system, the current version of the IFD (Release 10.1.0.0) is not a certified TAWS;

2.  The non-TAWS version of the IFD does not have Premature Descent Alarm (PDA) feature that a certified TAWS does.

3.  The non-TAWS version of the IFD does not have the Excessive Sink Rate feature that a certified TAWS does.

4.  The non-TAWS version of the IFD does not have the Negative Climb Rate after Takeoff or Go-Around that a certified TAWS does.

By way of reference the other two features that make up a certified TAWS system are the FLTA capability and the 500' call out capability.   Those are in the IFD now and will never be removed or face a $ up-charge.   The missing three features and TSO approval tag will have the $ up-charge when they are available.

It surely does! Good catch.
