According to the interview survey, I noticed that flight crews (i.e. pilots and dispatchers) today perform in-flight re-planning manually. Since then, I have been thinking about whether the manual process is an issue.
I had a chance to speak with some dispatchers. They claimed that the manual decision-making process may not be an issue because they generally make the right decision regarding safety.
However, as an engineer, I think that the advent of new communication and technology (e.g. sharing weather information between aircraft in flight) will bring more information into the cockpit in the future; therefore, flight crews may be faced with information overload. This could prevent them from making quick decisions, which leads to potential human error.
Since I am not a pilot (or dispatcher), I may be wrong. So, please let me correct if I am wrong. Also, it will be appreciated if you can share your opinions on this.
