Embodiment approach

[0056] According to some preferred embodiments of the present invention, the method may also include:

[0057] In takeoff thrust control mode, in response to retracting the throttle stick below the mode switch detent (e.g. figure 1 retract the throttle stick from right to left to the left side of the mode switch position as shown in , the aircraft switches from the takeoff thrust control mode to the normal thrust mode, and the normal thrust mode defines the corresponding thrust power and aircraft attitude mode ;

[0058] In the normal thrust mode, the throttle lever follows the operation of the engine in the second gear range of the throttle console, and the second gear range is the interval from the slow stop stop position of the throttle console to the mode switching stop position.

[0059] Further preferably, the method may also include:

[0060] In the normal thrust mode, in response to the operation of pushing the throttle stick beyond the mode switching position, the a...

Abstract

The invention discloses a method and system for controlling the navigational speed and attitude mode of an aircraft. The aircraft comprises an engine and a thrust control device which can control theengine to operate and is provided with an accelerator platform and an accelerator rod. The method comprises the steps that when the aircraft is located on the ground, in response to the operation of pushing the accelerator rod to exceed a mode switching clamping position, the aircraft enters a take-off thrust control mode, corresponding thrust power and the aircraft attitude mode are defined in the take-off thrust control mode, and the mode switching clamping position is arranged in the accelerator platform; in the takeoff thrust control mode, the accelerator rod follows up in a first gear interval of the accelerator platform according to the operation of the engine, and the first gear interval is an interval from the mode switching clamping position to a front stop position. According tothe method and the system for controlling the navigational speed and the attitude mode of the aircraft, through the follow-up accelerator platform device with the set or fixed mode switching clampingposition, the improvement of the control reliability and the convenience degree is facilitated, and the flight safety risk is reduced.

Description

technical field [0001] The invention relates to the field of aircraft body design, in particular to the control of aircraft speed and attitude mode, and in particular to a method and system for controlling the aircraft speed and attitude mode. Background technique [0002] With the development of aviation technology, especially the technology related to automatic flight control, the aircraft can perform automatic or semi-automatic control of the speed and flight attitude at all stages of flight to assist the pilot to control the flight of the aircraft. However, there are still many deficiencies in the current existing solutions in terms of specific control methods related to the relative control of the aircraft's speed and flight attitude. [0003] As we all know, the pilot needs to control the thrust of the engine by manipulating the throttle console device during normal flight control. In short, a throttle console device in an existing aircraft generally includes a thrott...
