Cautions are always designed to occur prior to warnings during steady-
state flight. There are exceptions such as initiating turns into terrain or
initiating a descent when close to terrain. Under these conditions a
Warning may be received without a Caution.
In some cases, a terrain alert may be issued while flying toward an
obstacle. This will occur when terrain beneath the obstacle is within the
terrain alerting buffer. Terrain alerts always take precedence over obstacle
alerts. If an obstacle is within the alerting area it will show on the display.
