Purchased and installed the XP11 Falcon FA50 EX.  Love the aircraft, but was curious on why I do not hear any GPWS.  I also have dndesign Challenger CL30, which is also a great aircraft, but it DOES have GPWS.  Is there an option on the Falcon to use this?

Thanks,
Rob

You could try editing the plane in planemaker. Do make a backup of the plane first, if you are not familiar with plane maker, or if you want to revert some settings to the original.

Open the plane in planemaker, go to Expert > Special Equipment, and try checking "has airliner aural warning system". You can also check the "verbal 500 AGL callout equipped".

When you are done editing the plane, go to File > Save. Close plane maker and start X plane, then see if that worked.
