During normal nosewheel steering, what angle does the nosewheel typically deflect?

• A. 4°
• B. 8°
• C. 12°
• D. 15°

Answer: (B)

Normal nosewheel steering in a small tricycle-gear airplane uses a modest nosewheel deflection to provide steering control on the ground without risking tire scrub or excessive loading. The nose wheel is designed to deflect only a small amount, about 8 degrees to either side. This angle gives a practical turning radius at taxi speeds while keeping steering forces manageable and the tire and gear system from being overstressed. If the wheel turned more than this, the tires would scrub more, steering feel would become less stable, and there could be more wear or potential damage to the nose gear or fusalage contact risk. Smaller deflection would make turning too sluggish and require more rudder input, while larger deflections aren’t how the system is designed to operate. So, the typical nosewheel deflection during normal steering is about eight degrees.
