According to the invention, passengers are supplied with a first fraction of oxygen-enriched air from independent supply means, in particular high-pressure cylinders (16), during a descent phase in which the aircraft descends from a normal cruising altitude to an intermediary diversion altitude. Moreover, compressed air is taken from the aircraft's own compressed air source in order to produce (in 2) a second fraction of said oxygen-enriched air, which is delivered to the passengers at least during a stabilised flight phase of the aircraft at an altitude close to the diversion altitude, above 5,500 metres.
Selon ce procédé, on fournit aux passagers une première fraction d'air enrichi en oxygène, à partir de moyens de fourniture inépendants, en particulier de bouteilles haute pression (16), pendant une phase de descente de l'aéronef entre une altitude normale de croisière et une altitude de déroutement intermédiaire. On prélève par ailleurs de l'air comprimé à partir d'une source d'air comprimé propre à l'aéronef pour produire (en 2) une seconde fraction dudit air enrichi en oxygène qu'on délivre aux passagers, au moins lors d'une phase de vol stabilisé de l'aéronef, au voisinage de l'altitude de déroutement, supérieure à 5 500 mètres.
