  Maybe the hot tip would be to use the sound of something grinding.
  In the alarm business, I had a "glass break simulator" that was
essentially
  a digital recording of breaking glass.  That was quite an attention
getter.

 Or use the sound of the pilot swearing.
Or a Radio Shack piezo buzzer (smoke alarm.)  In fact it is so loud that I
mounted it in a sound attenuation box.
It is actuated when flap setting is greater then 40 degrees and gear is up.
