ConditionCondition

Pression pompe carburant basse — voyant LOW PRESSURE (main ou CTR).Fuel pump pressure low — LOW PRESSURE light (main or CTR).

ObjectifObjective

Distinguer pompe vide / panne / cavitation vs FILTER BYPASS ; ouvrir Urgence pour les étapes.Distinguish empty / failed / cavitation pump vs FILTER BYPASS; open Emergency for steps.

LOW PRESSURE à la mise ON ou au taxi → ne pas traiter comme « normal ». Vérifier quantité / switch / MEL avant départ.LOW PRESSURE on switch-on or taxi → not “normal.” Check quantity / switch / MEL before departure.

In FLT

CTR LOW PRESSURE souvent = CTR vide (attendu si scavenge / empty). Main LP avec fuel restant = panne pompe ou cavitation — suction feed possible côté concerné.CTR LOW PRESSURE often = CTR empty (expected if scavenge / empty). Main LP with fuel remaining = pump fail or cavitation — suction feed possible on that side.

≠ FILTER BYPASS — contamination filtre moteur, autre lumière, autre NNC (12.5).≠ FILTER BYPASS — engine filter contamination, different light, different NNC (12.5).
