[2] In 2006, Airbus was quietly polling airlines to see about the viability of a perch seat,[1] which it had created in 2003.
The design was expected to start undergoing safety trials in the 2011–2012 time frame.
[7] The Ryanair design would have passengers perched on a narrow shelf, with their weight taken up by their legs, and their back against the seatback, strapped in, with additional shoulder restraints similar to roller coaster overhead restraints.
