Final answer:
The statement is false. Pressing and holding the nosewheel steering button a second time with the wings spread and locked will not select the high mode and display NWS HI on the HUD.
Step-by-step explanation:
The statement in the question is false. In an aircraft, pressing and holding the nosewheel steering (NWS) button a second time with the wings spread and locked will not select the high mode (±75°) and display NWS HI on the HUD (Head-Up Display). This is because the NWS button is used to activate and deactivate the nosewheel steering system, which controls the direction of the aircraft's nosewheel during taxiing. The high mode allows for a larger steering angle, but it is usually engaged using a different method or switch, not by pressing the NWS button again.
