The invention relates to the monitoring of the landing flaps on an airfoil (2) for an aircraft (1), and to an aircraft (1) having such an airfoil (2). The airfoil (2) has a wingbox (3), a support (5) which is mounted relative to the wingbox (3) such that it can rotate with respect to a flap rotation axis (7), a flap (4) which is attached to the support (5) and rotates with respect to the flap rotation axis (7) during rotation of the support (5) relative to the wingbox (3), a movement mechanism (8) which is coupled to the support (5) in order to set an angle position of the flap (4) with respect to the wingbox (3) and a measurement apparatus (18) for detection of the angle position of the flap (4). The measurement apparatus (18) has a rotation sensor (19), which is arranged on the support (5), and a four-element coupling transmission (22, 24, 26, 27) which couples the rotation sensor (19) to the movement mechanism (8).

1. Airfoil for an aircraft, comprising a wingbox,a support which is mounted relative to the wingbox such that it can rotate with respect to a flap rotation axis,a flap which is attached to the support and rotates with respect to the flap rotation axis during rotation of the support relative to the wingbox,a movement mechanism, which is coupled to the support, for setting an angle position of the flap with respect to the wingbox anda measurement apparatus for detection of the angle position of the flap, the measurement apparatus having a rotation sensor, which is arranged on the support, and a four-element coupling transmission which couples the rotation sensor to the movement mechanism. 2. Airfoil according to claim 1, in which the movement mechanism comprises a spindle, a spindle nut, which is coupled to the support, and a drive, and the four-element coupling element is coupled to the spindle nut, the drive rotating the spindle about its longitudinal axis in order to set the angle position of the flap, such that the spindle nut is moved along the longitudinal axis of the spindle and thus rotates the support about the flap rotation axis. 3. Airfoil according to claim 1, in which the four-element coupling transmission comprises a first lever arm and a second lever arm which is connected in an articulated manner to the first lever arm, the first lever arm additionally being connected to the rotation sensor at a sensor rotation point, and with the second lever arm being connected in an articulated manner to the movement mechanism at a connection point. 4. Airfoil according to claim 3, in which the second lever arm is connected in an articulated manner to the spindle nut at the connection point. 5. Airfoil according to claim 4, in which the spindle nut comprises a universal joint, by means of which the second lever arm is connected in an articulated manner at the connection point and to which the support is attached such that it can rotate with respect to a rotation axis. 6. Airfoil according to claim 5, in which the four-element coupling transmission forms a quadrilateral whose sides are formed by the first and second lever arm as well as the connection paths between the sensor rotation point and the rotation axis, and the connection point and the rotation axis. 7. Airfoil according to claim 6, in which the quadrilateral is a parallelogram. 8. Airfoil according to claim 1, in which the flap is a landing flap. 9. Airfoil according to claim 1, comprising a further support, to which the flap is attached and which is mounted with respect to the flap rotation axis such that it can rotate relative to the wingbox, a further movement mechanism which is coupled to the further support for adjustment of the angle position of the flap, and a further measurement apparatus for detection of the angle position of the flap, the further measurement apparatus having a further rotation sensor which is arranged on the further support, and having a further four-element coupling transmission which is coupled to the further movement mechanism. 10. Aircraft having at least one airfoil according to claim 1. 11. Aircraft having at least one airfoil according to claim 9 and having an evaluation device, which is connected to the two rotation sensors, for evaluation of signals which originate from the rotation sensors. 12. Aircraft according to claim 11, in which the evaluation device forms a differential signal from the two signals from the rotation sensors, and if a limit value is overshot or undershot, deduces an incorrect operating state of the flap, and/or of at least one of the two movement mechanisms.
