1. A water scooping apparatus for an aircraft, comprising:
an extendible tubular member having a first end and an opposite end, wherein the first end is pivotally attachable to the aircraft, the extendible tubular member being at least partially retracted when the water scooping device is in an inactive state and extending downwards from the aircraft at an angle when the water scooping device is in an active state;
a duct for fluidly connecting a water tank of the aircraft to the first end of the extendible tubular member;
a water scooping unit that is fluidly connected to the opposite end of the extendible tubular member, the water scooping unit being provided with an intake opening that is in fluidic communication with the extendible tubular member and that is arranged at a side of the water scooping unit that faces away from a sky when the water scooping apparatus is in the active state, the water scooping unit being provided with a plurality of surface-piercing hydrofoils, characterized in that the surface-piercing hydrofoils of said plurality of surface-piercing hydrofoils being arranged surrounding the intake opening in such a way that as seen in a direction parallel to a longitudinal centerline of the water scooping unit a first pair of surface-piercing hydrofoils is arranged upstream of the intake opening and a second pair of surface-piercing hydrofoils is arranged downstream of the intake opening, the surface-piercing hydrofoils of each of the first pair of surface-piercing hydrofoils and the second pair of surface-piercing hydrofoils being configured for generating an upward force when being moved through a body of water when the water scooping apparatus is in the active state that positions the water scooping unit with respect to a surface of the body of water in such a way that ensures water intake via the intake opening.
