Webbspeed of sound is 340.3 m/sec but at an altitude of 15 kilometers where the temperature is down to 216.7 K the speed of sound is only 295.1 m/sec. This difference indicates that an airplane flying at this altitude encounters the speed of sound at a slower speed, and, therefore, comes up against compressibility effects sooner.

A simple hinged flap reduces landing speed to 81 mph. A split flap reduces it to 78 mph. A slotted trailing-edge flap brings the landing speed down to 75 mph, and a double-slotted flap to 70 mph. cindy johnson dancing nurse photos
