What is the maximum operating speed at which the landing gear is down?

• A. 130 KIAS
• B. 150 KIAS
• C. 180 KIAS
• D. 200 KIAS

Answer: (B)

The maximum operating speed at which the landing gear can be down reflects the safe operational limits to prevent structural damage and ensure optimal performance during flight configurations. The value of 150 KIAS is critical as it denotes the threshold speed at which pilots can safely operate with the landing gear extended without risking adverse aerodynamic effects.

Exceeding this speed with the landing gear down could lead to increased stress on the gear structure and could affect the plane's handling characteristics. Knowing the specific operating limits, such as this maximum speed, helps maintain safety and compliance during flight operations, particularly during critical phases such as approach and landing. Understanding and adhering to these limits is essential for effective aircraft management and reduces the likelihood of operational incidents.
