What are some things that can be added or done to a typical small aircraft to improve comfort and/or safety? For example, I saw some other posts that said some folks will replace weather stripping for sound reduction in the cabin. As for a safety feature example, I just learned what a tail skid is and how simple it is as well. On that same note, what are some additional easy add-ons or modifications one can make to make their aircrafts more comfortable and/or safer? Thanks for reading!
