Problems solved by technology
In previous flight tests, the pilots mainly controlled and maintained the airspeed according to the airspeed instructions. In fact, the efficiency of this control method is not high. At the same time, the test pilots must have high driving skills and a high degree of concentration to meet the requirements

Embodiment Construction
[0012] The principle of the present invention: when the power and configuration of the aircraft are determined, the entire process of manipulating the aircraft is to first change the attitude of the aircraft, then change the aerodynamic force acting on the aircraft, and then change the airspeed. That is to say, when the power and configuration of the aircraft are determined, the pilot can achieve precise control and maintaining airspeed by precisely controlling and maintaining the aircraft attitude. However, the attitude indication accuracy of the integrated display system of the Yun 12F aircraft is too rough, and the pilot cannot achieve the precise maintenance of the aircraft attitude. In response to the above problems, an "additional scale" was designed to improve the accuracy of the aircraft's comprehensive display system.
[0013] The present invention will be described in detail below in conjunction with the accompanying drawings of the specification.

The invention discloses an additional scale method in a flight test, and belongs to the technical field of flight tests. When the power and structure of an airplane are determined, the whole airplane operating process comprises the steps that the attitude of the airplane changes at first, pneumatic force acting on the airplane changes and then airspeed changes. In other words, on the condition that the power and structure of the airplane are determined, a pilot can achieve the purpose of precisely controlling and keeping the airspeed by precisely controlling and keeping the attitude of the airplane, however, the attitude indication precision of a shipment 12F airplane comprehensive display system is excessively rough, and the pilot cannot precisely keep the attitude of the airplane. In order to solve the problem, an additional scale is designed to improve the indication precision of the airplane comprehensive display system. The method effectively improves the test flight quality and efficiency of airspeed calibration test flights.
Description
Technical field [0001] The additional scale method in the flight test of the present invention belongs to the technical field of flight test. Background technique [0002] In the airspeed calibration test flight of the Yun 12F aircraft, the pilot is required to accurately control and maintain the airspeed. In previous flight tests, pilots mainly controlled and maintained airspeed based on airspeed instructions. In fact, the efficiency of this control method is not high. At the same time, test pilots must have high driving skills and high concentration. To meet the requirements. Summary of the invention [0003] The purpose of the invention: The invention is mainly to improve the accuracy of airspeed maintenance and reduce the mental pressure of test pilots. [0004] The technical scheme of the invention: the additional scale method in the flight test, the method adopts the following steps: [0005] The first step is to accurately measure the pitch and attitude indication scale on t...
