the pilots are in a state of vigilance which requires a certain level of arousal to be effective.
the pilots should divide attention to scan instruments individually.
the pilots are experiencing cocktail party effect.
the pilots do not need to scan the instruments, since their attention mechanism can monitor all instruments simultaneously.
This question presents a notable challenge, initially seeming to have two plausible answers. Let's break down each of these options:
- "The pilots are in a state of vigilance which requires a certain level of arousal to be effective."
- "The pilots should divide attention to scan instruments individually."
To begin, it's essential to distinguish between divided attention and selective attention.
Selective Attention: This type of attention involves continuously sampling incoming information to determine its relevance to the current task at hand. Certain stimuli, such as our names or callsigns, have a strong ability to capture our attention. Selective attention allows the individual to prioritize and process the most important or relevant information and helps him/her to concentrate on a particular stimuli.
Divided Attention: Divided attention refers to the ability of our central decision-making system to distribute its focus among multiple tasks. For example, a pilot flying a visual approach must divide their attention between maintaining the correct approach path and regularly checking instruments for critical information like airspeed, altitude, and engine performance.
This specific question mentions that pilots are engaged in instrument monitoring. It's safe to assume that automation is in use, meaning the pilots would mostly be employing selective attention.
It's worth noting that the initial feedback did not specify which option EASA considered correct. Therefore, we would greatly appreciate any additional feedback on this question.
