The maximum value of the angle of turning of the nose gear large jet aircrafts, is limited to A. 20° B. 30° C. 45° D. 60°

The correct answer is A. 20°.

The nose gear of a large jet aircraft is the wheel at the front of the aircraft that allows it to steer. The angle of turning of the nose gear is the maximum angle that the nose gear can turn from its straight-ahead position. This angle is limited to 20° to prevent the aircraft from tipping over.

Option B is incorrect because the maximum angle of turning of the nose gear is 20°, not 30°.

Option C is incorrect because the maximum angle of turning of the nose gear is 20°, not 45°.

Option D is incorrect because the maximum angle of turning of the nose gear is 20°, not 60°.
