This paper proposes a distributed collaborative time difference control algorithm based on speed regulation and distance compensation, which addresses the challenge of achieving the target operation point within a preset time difference range for coordinated flight of two aircraft in general aviation. After in-depth research and analysis, this algorithm is developed. This algorithm prioritizes the use of variable gain speed adjustment, allowing for flexible adjustment within a range of ±15% indicated airspeed (IAS). When the speed adjustment reaches the extreme value but still cannot meet the coordination requirements, the leading aircraft triggers the adaptive waiting program and enters the waiting area to execute the waiting flight action, in order to achieve the effect of distance compensation and ensure that the time difference between the leading and trailing aircraft is always maintained within the preset range. At the same time, research is being conducted on distributed control systems based on electronic flight bag (EFB) to build a real-time information exchange and collaborative decision-making platform. This platform supports the integration of real-time trajectory data from Automatic Dependent Surveillance-Broadcast In (ADS-B IN), which presents the obtained aircraft position, speed, heading and other information to pilots in digital form, significantly enhancing their situational awareness ability. The platform also supports real-time visual guidance instructions for pilots, such as acceleration/deceleration, entry and exit waiting points, based on collaborative time difference control algorithms, to comprehensively assist in the safe implementation of dual aircraft collaborative operations in navigation and promote the advancement of dual aircraft collaborative operations to a higher level.
