Modern aircraft are investing and becoming more reliant on automation for efficiency and safety. Nevertheless, the Human interface has a potential of causing both positive and hazardous incidences if mishandled or misunderstood. It may lead to aircrafts undesirable development which eventually it leads to difficulties in the application of the conventional flying techniques.
Positive impacts
They are various attributes involved with these interfaces: the interface can relieve the pilots of the repetitive yet non-rewarding functions less suited for humans. They invariably change the role of the pilot in the deck into a monitoring role. Excellent interfaces reduce work overload and free people attentions into focusing on more important matters (Taylor, 2017). The diagnostic feature and the system monitoring displays do support and allow for the maintenance of pilots and the staff through understanding the state of the aircraft. The interfaces have also shown to improve the comfort of passengers; it reduces the weather minima and has a positive impact on the establishing of flight path control.

Hazard and related issues
Within the flight crew, the main issues which may lead to risk include the fact that the traditional, cognitive and manual flying skills may face a sudden decline due to lack of practice on the aircrafts. The situation further exacerbates if the operator discourages or limits the usage of manual modes. They are also much-unexpected automation behavior like the un-commanded disengagements due to system failure (Van Marwijk, 2011). Another hazard is perhaps pilot’s distraction by the interfaces, and this leads to adverse consequences. The safety issues that arise due to dependency on the interface include the fact that if the interface fails to connect, then the burden left to pilots become slightly beyond their capabilities. Finally, is the lack of clarity, when the alarm goes off it only indicates the problem and not solution.
