[0005] The positive thrust handle 1 is cylindrical, and the cross-sectional diameter is 37mm±0.5mm.

[0006] The distance between the take-off and landing unit mounting frame 3 and the rotation center of the positive thrust handle 1 is 31mm±1mm.

[0007] The installation angle of the take-off and landing unit mounting frame 3 is 32°±0.5°.

The pilot only needs to tap his index finger to trigger the takeoff and go-around switch. While avoiding accidental touches, it reduces operating actions, improves operational convenience, is more ergonomically designed, and improves flight comfort and safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 Schematic diagram of the forward thrust and takeoff and go-around operating devices;

[0012] Among them: 1-forward thrust handle, 2-forward thrust rod, 3-takeoff and go-around unit mounting bracket, 4-takeoff and go-around unit, 5-pressure plate. DETAILED DESCRIPTION

[0013] The present invention will be further described below with reference to the accompanying drawings:

[0014] like Figure 1 As shown, the positive thrust and takeoff and go-around operating device mainly consists of a positive thrust handle 1, a positive thrust rod 2, a takeoff and go-around unit mounting frame 3, a takeoff and go-around unit 4, a pressure plate 5, a bushing 6, screws, a pin shaft and a gasket.

[0015] The positive thrust handle 1 is designed to be cylindrical in accordance with the requirements of CCAR25R4 Section 25.781 on the shape of cockpit control handles. After two rounds of ergonomic evaluations by pilots, the current cross-sectional diameter of the positive thrust handle is 37mm, which meets the pilot's operational needs.

[0016] The positive thrust rod 2 is a component for transmitting the control force load. The upper end is connected to the positive thrust handle 1, and the lower end is connected to the transmission mechanism of the throttle control panel. The takeoff and go-around unit mounting bracket 3 is installed on the positive thrust rod 2.

[0017] The takeoff and go-around unit mounting bracket is installed at the waist of the forward thrust lever 2, 31mm from the rotation center of the forward thrust handle 1, at a 32° installation angle, and 16mm from the vertical centerline of the forward thrust lever 2. The takeoff and go-around control unit 4's pressure plate 5 and screws are installed on the takeoff and go-around unit mounting bracket 3, allowing the pilot to complete the takeoff and go-around operation without making any obvious movements while holding the forward thrust handle.

[0018] Two outgoing lines of the take-off and re-flight operation unit (4) are connected to the related pins of the throttle stand connector. The superior system receives the take-off and re-flight unit signal, and the superior system transmits the signal to the drive control unit of the throttle stand after conversion. The drive control unit drives the throttle stand positive thrust rod to realize the take-off and re-flight operation of the aircraft.

[0019] The specific working principle is:

[0020] 1) When the aircraft needs to take off and re-fly, the pilot's index finger triggers the take-off and re-flight switch. The signal is transmitted to the superior system through the throttle stand connector. The superior system converts the signal and transmits it to the drive control unit of the throttle stand through the related pins of the throttle stand connector. The drive motor rotates, and the motor drives the positive thrust rod to move through the gear, reliably realizing the take-off and re-flight operation of the aircraft.

[0021] 2) When the aircraft does not take off and re-fly, the pilot normally holds the positive thrust handle of the throttle stand and controls the positive thrust rod. The design of the positive thrust handle, the installation position of the take-off and re-flight switch and the angle design avoid the accidental touch of the take-off and re-flight switch when the pilot normally controls the positive thrust.
