Some features that have already been described in connection with other figures are not described again for the sake of clarity. For the sake of clarity, some features that are shown multiple times in the figures are not provided with a reference numeral, for example, the electrical contacts (reference numeral 29 in Fig. 1 ).

[0048] Fig. 1 shows a schematic sectional view of a base system 1 according to the invention. The base system 1 comprises a base flange 3 with a base base 9 and a tubular receptacle 7. The base flange 3, as well as the tubular receptacle 7 of the base flange 3, extend along a vertical axis 10 of the base system 1. The tubular receptacle 7 comprises a tapered region 15, which is arranged axially in a region of the tubular receptacle 7 adjacent to the base base 9. The base flange 3 has socket projections (in Fig. 1 concealed, see for example base projections 13 in Fig. 4 ) to prevent rotation of a handle adapter plate.

[0049] The base flange 3 is in the Fig. 1 designed as a force sensor. In the tapered area 15 of the base flange 3, sensors (not shown) are arranged, in the embodiment of the Fig. 1 Strain gauges are arranged. The sensors are configured to determine forces exerted on a control stick attached to the base system 1, for example, by a pilot's hand while controlling an aircraft. In particular, the sensors determine forces in the direction of a roll axis and a pitch axis, which are oriented orthogonally to the vertical axis 10 and orthogonally to each other. The sensors are covered by a sensor cover 21 and protected from the outside.

[0050] The base system 1 comprises a base nut 5, which surrounds the tubular receptacle 7 in the circumferential direction around the vertical axis 10. The base nut 5 has an interface 11 radially on the outside, which is designed for connection with a grip nut. Fig. 1 The interface 11 is designed as an external thread of the base nut 5. The base nut 5 has a fastening opening 31 for attaching a safety wire.

[0051] The base nut 5 is in the Fig. 1 secured by securing segments 19 against slipping from the tubular holder 7. The securing segments 19 are partially accommodated in a groove 17 of the base flange 3. The groove 17 is in the Fig. 1 for example, as an annular groove in the circumferential direction around the tubular receptacle 7.
