The biggest issue with this legislation is the one size fits all approach that has been adopted. I can understand that there are high intensity operations (such as regional flying) where it’s neither easy nor practical for pilots to be using PEDs in “Cruise”. Indeed if there have been incidents where safety has been compromised then I understand the need for regulation. Such intense operations involve so much work, it’s easy to forget who you are let alone have the time to do anything of a personal nature on the flight deck.
However, it’s painful to see that the FAA have not considered/chosen to ignore the other side of the coin where sector lengths of 3+ hours flying over water and desert are concerned.
