Check out your AFM (Flight manual) from which the Airbus procedures are derived. Airbus do not differ from the AFM - so when the TRE or whomever decides to be different to Airbus/Boeing they normally end up being different to the Flight manual.
Be very interesting explaining that your position as a Company TRE..etc gives one the authority to overrule the certifying authority - in the airbus case the European Aviation Safety Agency.
