DFW Instructors 300/350 Practice Test

An amber square with amber diagonal lines on the EICAS (Engine Indication and Crew Alerting System) signifies that the landing gear is not in a safe position, meaning it is neither fully retracted (up) nor fully deployed and locked (down). This indicator warns the flight crew that the landing gear is in an ambiguous or unsafe state and requires their attention. This alert serves a crucial purpose in maintaining safety during the flight, alerting pilots to a potential issue with the landing gear system that could prevent a safe landing. When pilots see this indication, they are prompted to check the landing gear position and take any necessary corrective action. The other choices do not convey the situation accurately: indicating that the gear is up or down and locked would provide a reassurance that the landing gear is in a confirmed state, while stating that the gear handle position is correct does not address the underlying issue highlighted by the amber warning.
