The CRiSTA project was started based on the request for a multi-functional cabin rest area. Initially the problems/issues being addressed by the project were defined as: crew fatigue during long range flights, increased numbers of medical emergencies by ageing passengers and the wish to fulfill cultural needs on board. During our investigations it became clear that these problems/issues are actual and have become more relevant for the A320 neo for which we are designing this multi-functional cabin rest area. The A320 neo has a longer range than its predecessor and airlines will start to use it for trans Atlantic flights. This causes unions to urge airlines to allow for decent crew resting on these flights. Furthermore a medical incident could have a big impact on catering and passenger comfort during a long range flight in case it would need to be handled in the aisle. Finally things like baby care also become more urgnet during the longer flight in the narrow body aircraft.
Our multi-functional cabin rest area should make sure that the well being of both crew and passengers is taken to higher level on the long range narrow body flights on the A320 neo. As a society we want our air travel to be safe and comfortable and these are the main topics CRiSTA addresses. Next to this we are confident that with the medical and communication equipment we intend to incorporate in the area we can also decrease the amount of diverted flights and fuel dumped, which is also an important factor for society.
The overall objectives have been defined as:
- allowing for real long range capability of the A320 neo aircraft
- giving the airline flexibility to use the space they way it fits their business model best
- enabling the highest possible degree of medical care on narrow body aircraft
- enabling the use for cultural needs, like praying, meditation, infant care etc.
After design, construction, shipping and testing we found that to make a viable product out of this demonstrator several changes will be required based on the following outcomes:
- The foldable bench is not suitable for use with passengers that are not mobile and cannot be used for CPR.
- It would be better to add an additional High Comfort Cabin Attendant Seat (HCCAS) instead of the foldable bench.
- Resting with two crew members at once is challenging as the space is very limited and there is no privacy.
- The extended workdeck will not be used as it takes time to set up (a general problem for multi functionality).
- The crew really likes the space, but is not eager to share the space with passengers.
- Hygene wise there are concerns to use the space for baby care.
Concluding, to create an actual product out of this demonstrator additional research and development will be needed as on all three main topics (crew resting, medical and passenger experience) have at this moment major concerns. The space is too expensive to use only during the very limited time of resting during the flight.
