    The listed means of compliance have been found acceptable and 
historically successful, but they are not the only methods that can be 
used to show compliance. In some cases, highly sophisticated airplanes 
may require more accurate or substantial solutions. Accordingly, the 
FAA is proposing and requesting comments on AC 23.1419-2C.
