   Airspeed can be cross-checked by power setting, attitude, and
   vertical speed.  Not as accurate, but good enough to get me through
   my "emergency", landing without an airspeed indicator, in my
   checkride.  And something I cross checked when I got ice on my pitot,
   while I was waiting for the heater to catch up.
