Does anyone know if the EASA notice is based on some new input (presumably from early readout of Ethiopian FDR) ?
If not I think this is draconian and frankly unwarranted - they could at the very least allow en-route flights to operate normally as the issue - if there is actually one - is in the takeoff phase.
On a different topic can anyone explain how an automation system (regardless of brand/purpose), let alone on a modern airliner, can be certified with only one control source ?
