Abstract

processo de sincronização dos motores de um avião, de acordo com uma lógica de ativação que possui um estado desativado (20), um estado armado (22) e um estado ativado (16), no qual: a passagem (36) da sincronização do estado armado para o estado ativado é operada através sucessivamente um primeiro e depois um segundo estado intermediário (38, 39) da lógica de ativação; e para qualquer passagem da lógica de ativação do segundo estado intermediário (39) para o estado ativado, são efetuados: uma tomada em consideração, em cada motor, do estado de ativação da sincronização, e uma troca desse dado entre os motores, sendo que a passagem da lógica de ativação para o estado ativado de um dos motores impõe que as condições de segurança e de ativação do outro estejam todas preenchidas; e se um dos motores passa para o estado desativado, o outro também, e para cada motor a passagem (36, 42) da sincronização do estado armado no primeiro depois no segundo estado intermediário seja operada automaticamente quando uma primeira parte e depois uma segunda parte das condições de segurança e/ou de ativação estão preenchidas.
