Hi Lou: Ok I'll try.I'm also a learner and have to often ask for help myself. FIRST OF ALL MAKE A SAFE COPY OF YOU 727 FILES AND FOLDERS BEFORE DOING ANYTHING TO THEM!!!!!!!!!.....I CANNOT STRESS THIS ENOUGH!...

Then go to your cap727 100/200 (?) folder under simobjects/airplanes in your main FSX folder,double click the 727's folder All the folder containing textures,aircraft.cfg,ai;.air file are in there Find your aircraft.cfg file and double click on it; It should open in "notepad" If it doesn't change the program to open it to notepad
Scroll down to the [GPSW] section and overwrite,make the nessesarry changes and save it, by choosing under file "save" Then go and test. Like you I get the callout "don't sink" which is ilogical upon descent to the runway; But I think this is a setting FSX is set for? That's why I suggest ticking off " Crashes and damages from the setting window in FSX. There's still lots of work to be done to the cap727- Look at Markos' and my posts. I just managed to install v2.4 for the sake of the weather radar...My favorite or I should say the one that gave me least H.A. was v2.2

Good luck
