Terrain Following and Terrain Avoidance (TFTA) supported by Synthetic Vision
In 2005, the FAA 727 was equipped with the Rockwell Collins team DELPHINS SVS
The system was used to fly Talon II missions along the Black Diamond training routes in New Mexico.
Special functions comprised 4-D guidance by means of both target speed cues on the SVS PFD and HUD, and indication of predicted location at the required time-over-target on the ND.
The guidance function was used to perform a simulated point in space approach down to 50 feet for a simulated high speed low altitude drop of cargo.
Off-path TF/TA guidance was provided using a forward projected path on the SVS display that locked at 500 ft above the terrain.
