An assembly for an aircraft includes a variable area inlet (62, 78) for an aircraft propulsion system (22). The variable area inlet (62, 78) extends along a longitudinal centerline (34, 90). The variable area inlet (62, 78) includes an inlet structure (80), an inlet door (82), an inner inlet passage (84), and an outer inlet passage (86). The inlet door (82) is configured to axially translate from a closed position to an open position along the longitudinal centerline (34, 90). The inlet door (82) is configured to close the outer inlet passage (86) when the inlet door (82) is in the closed position. The inlet door (82) is configured to open the outer inlet passage (86) when the inlet door (82) is in the open position. The inner inlet passage (84) extends into the variable area inlet (62, 78) from a leading edge (92) of the inlet structure (80). The outer inlet passage (86) extends through the inlet structure (80) to the inner inlet passage (84).
