Mr. James Padden:

I will not repeat what has been said but in the UK we were angling to keep primary legislation as flexible as possible because this is an industry that will keep innovating quickly. As far as we are able to take broad powers, I would advise the committee to do so and put the detail into secondary regulations. It would agree about some of the ratings around mass and similar characteristics. Aim at top speed but do not worry too much about power because speed can be limited.
