The FAA published a public consultation document Friday that will mean at least another 30+ days to the recertification process and probably longer.
It creates a requirement that the MAX, which was allowed to fly with one of its two flight computers inoperative because both had backups, is no longer able to do so.
The new system architecture requires both computers to monitor each other so one being inoperative is no longer acceptable.
It also mandates a far more comprehensive training system on flight simulators.
The paper is open to public response and depending on the feedback will help determine how much longer the recertification takes.
Even if there are no objections to the technical documents proposals, testing of the finalised system is to be carried out, “with a number of different flight simulators and a varied range of pilots” – this will help ensure that all eventualities have been covered and any unexpected pilot responses identified and resolved.
Meanwhile Boeing is pushing hard the concern it has to shut down production soon if recertification doesn’t happen in the new year. The story spread through dozens of news channels yesterday.
The FAA appears unmoved, determined to avoid the accusations of being under Boeing’s undue influence.
