1. An apparatus for entering a flight plan into an aircraft navigation system, said apparatus comprising:
- an acoustic sampler adapted for sampling a microphone signal and generating an acoustic signal;
a waypoint identifier adapted for generating an identified waypoint from said acoustic signal and said flight plan; and
a navigation interface adapted for incorporating said identified waypoint into said flight plan and for transmitting and receiving navigation data to and from said aircraft navigation system,said acoustic sampler being further adapted to generate a speech flag signal indicating portions of said acoustic signal corresponding to combinations of pilot speech and cabin noise and portions of said acoustic signal corresponding to cabin noise only,said waypoint identifier being further adapted to generate said identified waypoint using said speech flag signal.
