Final answer:
Switching off A/SKID and N/W STRG disables the anti-skid system and nose wheel steering on an aircraft, affecting braking efficiency and ground maneuverability.
Step-by-step explanation:
When you switch off the A/SKID (Auto Skid) and N/W STRG (Nose Wheel Steering) on an aircraft, it leads to significant changes in the control and safety features of the plane. Turning off the A/SKID disables the anti-skid system, which helps prevent the wheels from locking up during braking, especially under harsh conditions such as a wet or icy runway. This can result in reduced braking efficiency and potential tire skid during landing or deceleration on the ground. Moreover, turning off the N/W STRG means that the pilot will not have control over the nose wheel steering, which is crucial for maneuvering the aircraft on the ground during taxi, takeoff, and after landing. Without nose wheel steering, the pilot would have to use other means such as differential braking or the rudder to steer the plane on the ground, which can be less effective and more challenging.
