Airplanes do not receive OtA updates, nor does every system have a backup. Airplane software is developed to a very high safety standards, which mostly, but not always works. But this is not applicable here. A key part of airplane safety is constant monitoring and maintenance. If a component needs a software update, some technician will manually perform the update and do the required tests. This simply can not work in automotive.
