This recommendation covers the life cycle of a product and is part of the NAAE General Aviation Recommendations (RG.Aero). The programme management activities described in RG.Aéro 000 40 relating to the programme management specification explain the management of the activities required to cover the scope of RG.Aéro 000 50, given that a product to be produced requires a programme. The aim of this recommendation is to establish a link between the RG.Aéro or other existing standard documents in order to specify and harmonise the rules to form the basis of the documentation system relating to any product during its life cycle.
