The passenger experience while boarding an airplane can be low. To improve the experience a light guiding system was developed which allocates and displays the passengers luggage space in the overhead bin. The allocated space is guided by a light strip in front of the display that blinks when a passenger comes close to
their allocated luggage space. A test was done with groups of 18 passengers to compare the traditional way of boarding with the new way of boarding and the experience was significantly improved. The system has potential, but more studies with larger groups and in a real flight are needed to check if this effect is still there.

This paper investigates whether spring-foam technology in an aircraft seatpan can reduce weight and at the same time provides equal or better comfort. Firstly, through literature studies and iterative design process a prototype seatpan was designed and developed using spring-foam technology. This was then tested against standard aircraft seat pan for comfort and discomfort; 22 participants were asked to sit in each seat for 90 minutes while filling out comfort and discomfort questionnaire every 15 minutes. At the end of each seating session, pressure map was taken of the seatpan. The results showed prototype seatpan having significantly higher initial comfort (~0 min.), and at the 35 and 50-minute mark than standard seatpan. Pressure map data showed pressure distribution of the prototype seatpan was found to be significantly closer to an ideal pressure distribution opposed to the conventional seatpan. In addition, the prototype seatpan had a significantly bigger contact area and lower average pressure suggesting a higher comfort. The seat-cushion weighs 20% lower than conventional seat-cushion. The study indicates that a seat pan design using spring-foam technology can be lighter and more comfortable than conventional foam cushion materials.
