Final answer:
The question regarding at what angle the spoiler light will illuminate cannot be answered without specific aircraft reference. Spoilers are crucial for controlling the aircraft's lift and roll, and the spoiler light indicates their deployment beyond a certain angle.
Step-by-step explanation:
In aviation, the spoiler light is an indicator to the pilots that the spoilers have been deployed on the aircraft. The correct answer to when the spoiler light will illuminate is not provided in the options A) 5 degrees, B) 10 degrees, C) 15 degrees, D) 20 degrees. Typically, the actual angle at which the spoiler light illuminates can vary depending on the aircraft's design and the manufacturer's specifications. Therefore, without specific reference to the type of aircraft or the manufacturer's guidelines, it is not possible to give a correct answer.
The functionality of spoilers is critical for controlling the roll of the aircraft or for helping to reduce lift during descent and landing. When spoilers are extended, they disrupt the airflow over the wings, which in turn reduces lift and increases drag. In the cockpit, the illumination of the spoiler light alerts the pilot that spoilers have been deployed beyond a predetermined angle
