An aircraft ram air channel assembly having: a first ram air inlet with a deflector protruding from the aircraft outer skin, the deflector guiding an air flow into a first ram air inlet channel; a second ram air inlet having a cross-sectional area flush with the outer skin, the second inlet being coupled to a second ram air inlet channel and arranged proximate to the first inlet upstream of the first inlet; and a flap pivotable about an axis between first and second operating positions. The axis is upstream of the first and second inlets and extends perpendicular to the air flow. The flap in its first position projects into the second inlet channel to control air flow through the second inlet into the second inlet channel, and in its second position projects into the air flow to prevent foreign objects from entering the first and second inlets.

1. A ram air channel assembly for an aircraft, comprising: a first ram air inlet having a protruding portion which protrudes from an outer surface of a section of an aircraft outer skin, wherein the first ram air inlet is coupled to a first ram air inlet channel,a second ram air inlet having a cross-sectional area arranged flush with the section of the aircraft outer skin, wherein the second ram air inlet is coupled to a second ram air inlet channel and arranged proximate to the first ram air inlet at a predetermined distance from the first ram air inlet upstream of the first ram air inlet,a flap which, at least in sections, is pivotable about an axis relative to the section of the aircraft outer skin between a first and a second operating position, wherein the axis is arranged upstream of the first and the second ram air inlet and extends in a direction substantially perpendicular to a direction of flow of an air flow passing the section of the aircraft outer skin, anda control unit for controlling an operation of the flap, the control unit being adapted to control the flap into its first operating position when the aircraft is flying at cruising altitude,wherein the flap in its first operating position allows outside air to flow into the second ram air inlet channel and projects into the second ram air inlet channel in order to control the air flow through the second ram air inlet into the second ram air inlet channel, and in its second operating position projects into the air flow passing the section of the aircraft outer skin in order to prevent foreign objects from entering the first and the second ram air inlet,wherein the first ram air inlet channel is configured to be coupled to a first outside air consuming system of the aircraft and the second ram air inlet channel is configured to be coupled to a second outside air consuming system of the aircraft, andwherein the first and the second ram air inlet channel are formed separate from each other such that the first and second outside air consuming systems can be supplied with outside air independently from each other without a connection being provided between the first and the second ram air inlet channel. 2. The ram air channel assembly according to claim 1, wherein the first and the second outside air consuming systems are selected from the group of a fresh air generation system of an aircraft air conditioning system, an emergency ventilation system, a system for unpressurized bay ventilation, a heat exchanger, and an auxiliary power unit. 3. The ram air channel assembly according to claim 1, wherein at least one of the first and the second ram air inlet channel, in an inlet region thereof, is provided with a linearly inclined wall portion. 4. The ram air channel assembly according to claim 1, wherein the protruding portion of the first ram air inlet has the shape of a scoop air inlet. 5. The ram air channel assembly according to claim 1, wherein the control unit is further adapted to control the flap into its second operating position during take-off and/or landing of the aircraft. 6. A method for operating a ram air channel assembly according to claim 1, the method comprising the steps: controlling the flap into its first operating position when the aircraft is flying at cruising altitude, andcontrolling the flap into its second operating position during take-off and/or landing of the aircraft.
