He has discussed the topic. He gave the advice that the OP should talk to the AFCO as they are the subject matter experts and would be able give him the gen, instead of a username on the internet possibly giving him wrong info.
He could have also advised the OP to use the search function as this topic will have been discussed on ARRSE before.
