Final answer:
The VNE (Velocity Never Exceed) is an established maximum airspeed for an aircraft. When exceeded, the airspeed indicator will alert the pilot by turning red and return to normal once the aircraft slows down below the VNE value.
Step-by-step explanation:
When the aircraft's indicated airspeed exceeds the VNE (Velocity Never Exceed) value, the pointer and readout will turn red to alert the pilot of the condition. The colors will return to normal (usually white or green) once the indicated airspeed has been reduced below the VNE value.
This critical speed is established by the aircraft manufacturer and exceeding it can lead to structural damage or failure. Therefore, the color change serves as an immediate visual cue to the pilot that the safe operational limits of the aircraft are being compromised.
The visual indication of exceeding VNE, turning the pointer and readout red, is a vital safety feature in aircraft. This speed limit, set by the manufacturer, safeguards against structural damage or failure. The immediate color change provides a clear and urgent visual cue, alerting the pilot to the compromised operational limits and prompting corrective action to ensure the aircraft's safety and integrity.
