As much as I can see that this would be a major roadblock for many people wishing to build hours here, I am surprised that it took them this long. Its not an answer to all the security problems but it will provide another block to attackers, unfortunately it will also be another hinderance for people of honorable intentions.
Would someone wishing to get a licence here be able to use the hours that they flew previously for the requirements? Or do they have to start from scratch? I am unfamiliar with the old and new regulations, as I dont have my FAR/AIM handy.
