Persons aboard an aircraft in flight need to maintain a correct seating posture. For the passengers, it is a matter of comfort, which is part of the entire flight experience. However, for the flight crew members, they need to be seated in a way that not only ensures comfort but also reduces fatigue from being seated in the same position for a considerable period of time. The ergonomic seat design should allow the pilots to operate the aircraft efficiently too.
The Ideal Ergonomic Aircraft Seat
- A headrest to support the neck and skull.
- A Lumbar-Dorsal-Support (LDS) to support the waist/ lower back area.
- When the upper body is in an upright position, the seat backrest must meet the back of the user.
- As different people have different heights, users should be able to adjust the height of the LDS to allow the LDS to support the waist/ lower area.
- A hollow backrest that inclined rearward to accommodate tall users and allows room in space-constrained situations (eg. Light propeller aircraft)
Advantages of Utilising Aircraft Seat Ergonomics
- The users are seated comfortably for better flight experience.
- The users are able to sit down and get up from the seat easily and quickly (Especially important during emergency evacuation).
- Flight crews are able to see the surrounding outside the flight deck clearly without having to lean forward for better view.
- Flight crews are able to view the flight instruments more clearly and easily due to their closer distance from the instrument displays
- Flight crews are more alert due to a good seating posture (Especially important for the flight crews, who need to stay vigilant at all times during the flight)
- Prevent users from feeling tired easily due to a uncomfortable seating posture (Especially important for the flight crews, who need to stay vigilant at all times during the flight makes controls easier)
- An ergonomic aircraft seat increases space in the cabin
- The probability of backbone injuries is reduced, especially during scenarios when pilot has to be ejected from the aircraft during emergencies
- To prevent health implications such as Deep Vein Thrombosis (DVT)
