How Monitoring, SOPs and Clear Communication Catch Deviations Before They Become Critical

Hey everyone and welcome back to this A320 Knowledge article.
Human beings, by nature, are prone to errors. In aviation, the stakes of these mistakes can be exceptionally high. That’s why effective monitoring is crucial: it serves as a safety net, allowing us to detect and correct deviations from the intended flight path before they become critical. But achieving this requires a disciplined approach, adherence to Standard Operating Procedures (SOPs), and clear communication among crew members.
In this article, we’ll dive into the importance of monitoring in aviation, how to manage distractions and complacency, and how the role of a non-handling pilot is integral to maintaining flight safety. By exploring these concepts, we can better understand how proper monitoring can be the difference between a routine flight and a potentially dangerous situation.
Let’s dive right in.

Why monitoring matters: the fine line between safe and unsafe
In aviation, human error is inevitable, but crew error can be the result of poor monitoring, communication lapses, or missed cues. Studies show that the majority of public transport accidents stem from crew error rather than individual pilot mistakes. That’s why monitoring: the act of continuously observing flight path parameters and communicating deviations: is critical. Without effective monitoring, there is a higher likelihood that minor, unnoticed deviations could escalate into major safety risks.
Imagine the handling pilot deviating from the flight plan or SOP without informing the non-handling crew. The non-handling pilot may not be aware of the change and, consequently, could fail to alert the handling pilot of any risks that arise. This breakdown in communication is a common cause of incidents. When the handling pilot deviates unintentionally: such as flying at an increased airspeed because of unexpected turbulence: they must verbally notify the non-handling pilot and clearly explain their intention to deviate from the plan.
Monitoring requires discipline and alertness. If both pilots adhere to SOPs, the non-handling pilot can trust that the handling pilot is flying in a predictable manner. If deviations are necessary, they must be communicated thoroughly. This ensures that everyone is on the same page, reducing the likelihood of mistakes caused by misunderstanding or confusion.
The dangers of optical illusions and unseen deviations
One of the more insidious challenges pilots face during an approach is vertical deviation. While lateral deviations are easier to detect: such as drifting off the centreline of the runway: vertical deviations can be nearly impossible to notice, especially when visual cues from the environment play tricks on the eyes.
Environmental factors, such as sloping runways, nearby terrain, city light patterns, or weather conditions like precipitation or varying visibility, can distort the pilot’s perception of the approach. This creates optical illusions that can cause even experienced pilots to misjudge their position. When the pilot becomes visual with the runway lights, they instinctively feel the urge to land, even when conditions dictate otherwise. This can cause the aircraft to sink dangerously without the pilots realising it.
A major part of preventing this scenario is mandatory monitoring during every approach. The non-handling pilot should read aloud the flight instrument parameters to verify the actual flight path. This ensures that the aircraft remains on the correct approach path, regardless of the deceptive external cues. The human brain, after all, will always want to land when the runway is in sight, but monitoring the instruments allows the crew to keep emotions and instincts in check.
Preventing crew error: the difference between pilot and crew error
“Pilot error” and “crew error” are terms that describe mistakes made in-flight. While the former is usually attributed to a single pilot’s actions, the latter involves a failure of the entire crew to function effectively as a unit. More aviation accidents are caused by crew error than by any other factor, making it essential to understand the causes of these errors and how to prevent them.
Crew error often results from a breakdown in communication, lack of attention, or failure to adhere to procedures. For instance, if one pilot becomes distracted or fails to monitor instruments properly, it can lead to misjudgments or missed cues that could compromise flight safety. The responsibility for preventing crew error rests with every crew member, but the non-handling pilot plays an especially critical role in maintaining vigilance and ensuring that no steps are skipped.
