What is the maximum allowable nosewheel angle when gross weight exceeds 490,000 pounds and taxi speed exceeds 20 knots?

• A. 10
• B. 15
• C. 20
• D. 25

Answer: (C)

The maximum allowable nosewheel angle when the gross weight exceeds 490,000 pounds and taxi speed exceeds 20 knots is 20 degrees. This specification is crucial for maintaining control of the aircraft during taxi operations, especially under the conditions of high weight and speed. At these parameters, an excessive nosewheel angle could lead to loss of directional control or excessive tire wear, which is critical for safety and operational efficiency. Understanding the limitations around nosewheel angle helps in ensuring that pilots operate within the aircraft's defined envelope, particularly when it involves heavy loads and higher speeds, which could amplify the challenges of ground maneuverability. Thus, knowing the precise limits contributes directly to effective handling and minimizes the risk of incidents during taxiing.
