Premature Descent, below glide path
TAWS PDA algorithm has determined the aircraft is below
glide path.
No communication with traffic sensor
The IFD is not receiving messages from the traffic sensor.
Contact a local dealer for service. This message is local if
independent traffic sensors are installed.
Traffic sensor has failed
The traffic sensor is reporting a failure or the IFD is
receiving invalid messages from the sensor. Contact a local
dealer for service. This message is local if independent
traffic sensors are installed.
The above alert is just an example. After "Traffic" will be
either "Low" or "High", then the bearing in clock direction,
then the distance in nautical miles. The long text omits
Low/High and instead shows target altitude in feet.
This is a traffic advisory with bearing information. Establish
visual contact with conflicting traffic in order to facilitate
avoidance maneuvers as necessary.
