What is the maximum speed for landing gear being down and locked?

The maximum speed for landing gear being down and locked is crucial for safe flight operations, as exceeding this limit can lead to structural issues or unsafe landings. In most aircraft, the specific maximum speed while the landing gear is extended, often referred to as Vlo (landing gear operating speed), is defined in the aircraft's operating manual.

In this case, the correct answer indicates that the maximum permissible speed with the landing gear down and locked is 220 knots. This figure is significant because it allows pilots to maintain a safe margin while approaching for landing, ensuring that any necessary adjustments can be made without risking damage or failure of the landing gear system.

Understanding the correct maximum speed ensures that flight crews can operate their aircraft within the safe limitations set by the manufacturer, promoting safety and operational effectiveness during critical phases of flight. In contrast, speeds beyond this limit could lead to various forms of aerodynamic stress which are potentially hazardous.
