The FAA doesn’t “help”. You submit what the FAA wants and if it is not sufficient (with the FAA it usually isn’t) they kick it back telling you it does not meet FAA requirements. Then it is up to you to guess what the FAA wants and resubmit. This back and forth can happen several times. Why else does it take over 18 months to get a certificate approved! As I said before the FAA needs to be taken out of the space/rocket business other than airspace allocation for launches before the FAA drowns the private rocket launch business in bureaucratic red tape!
