FLTA Inhibited and Off Messages
Should a FLTA alert be generated, there are several courses of
action that can be taken and the specific scenario will dictate the
optimum avoidance maneuver. For example, sometimes the best
course of action is to immediately add power and climb, yet
sometimes the best course of action may be a small heading
change, especially in the case of a single obstacle off the nose.
The pilot in command must assess the specific circumstances
presented and take action to avoid flight into terrain.
