Find out why aircraft manufacturers did not provide accessibility for their helicopters.
You have probably already come across a flight operation in which an elderly man had difficulty getting onto the aircraft, or even a woman wearing heels who felt the risk of hurting herself while descending from the helicopter. The loss goes beyond the lack of safety, these passengers will probably avoid using a helicopter in the future, as they felt real discomfort both when meeting the aircraft and when leaving and sometimes this even happens in a very conscious and decisive way in the mind of the passenger.
The limitation of accessibility for people with reduced mobility in helicopters was a problem that reduced the target audience and restricted the versatility of the helicopter exclusively for people with total mobility or on stretchers with no mobility at all.
But why manufacturers didn't provide accessibility to such an important audience and even with great commercial potential, the answer is even more rhetorical than we can imagine, there simply wasn't a solution that could deliver the necessary accessibility with the essential characteristics, of extreme lightness, flame-retardant material and ergonomic dimensions for disembarking that matched the dimensions required to be taken on board.
But why wasn't this product developed sooner? Carbon fiber is a very strong and light material, however for distributed pressures. If you apply a specific force, such as tightening a screw, to the carbon fiber, you will see it cracking easily.
