Final answer:
Stabilator indicators in aircraft might be replaced by modern avionics such as electronic displays or synthetic vision systems to communicate aircraft control surface status.
Step-by-step explanation:
The question seems to be related to aviation technology, specifically regarding a component of an aircraft's control surfaces. The stabilator, a movable horizontal surface on the tail of an aircraft, assists in controlling the pitch. If the stabilator indicators have been removed, they may have been replaced by an alternative system for monitoring and signaling the position and movement of the stabilator.
This could potentially be an electronic display, synthetic vision system, or other modern avionics that enhance the pilot's situational awareness and control of the aircraft. Without more context, it's difficult to determine the exact replacement, but advancements in avionics have led to more sophisticated instruments that convey information about aircraft attitude, position, and control surface status more accurately and intuitively than older mechanical indicators.
