How is a Primary failure indicated on the ECAM memo page?

A primary failure on the ECAM (Electronic Centralized Aircraft Monitor) memo page is indicated in amber with a box. This visual cue is crucial for pilots as it signifies a serious operational issue that requires immediate attention. The use of amber conveys that the situation is not critical yet, but it demands prompt action to mitigate any potential impacts on flight safety or performance.

The box surrounding the indication further emphasizes the need for attention, as it distinguishes primary failures from other types of messages or information that may appear on the ECAM. Understanding the color and format associated with various warnings and failures is essential for effective cockpit management and safety, thus reinforcing the significance of the amber box indication for pilots operating the A320.
