5. PHASE TWO: FORMAL APPLICATION. Upon satisfactory completion of Gates 1–4, the certificate holder may proceed to Phase Two. This phase involves the certificate holder submitting all their formal documentation (as required in Gates 1–4) to the FAA as outlined in Gates 5 and 6. The FAA will evaluate and validate the certificate holder’s documentation. Upon satisfactory completion of Gates 5 and 6, the certificate holder may proceed to Phase Three.

Based upon the certificate holder’s proposed AMOC, the certificate holder will develop and submit a proposed data collection plan and a data analysis plan for review, evaluation, and validation. The data collection plan will outline the resources and methods for collecting all measurements. The data analysis plan will describe the method(s) for analyzing the data and how the results will be applied to evaluate the effectiveness of the FRMS. At this stage, the primary focus for the FAA will be to determine that the data collection operation can be safely conducted. Secondly, the FAA will evaluate the effectiveness of the data collection plan and the data analysis plan. The certificate holder will revise, as necessary, their operational procedures for data collection, which will be reviewed and evaluated by the FAA prior to authorizing the certificate holder to collect data. The certificate holder will also revise the operating manual to direct flightcrew members, schedulers, dispatchers, personnel holding operational control and persons having direct management oversight of these areas to comply with the FRMS operation procedures whenever the FRMS is applied to a flight or series of flights.
