Embodiment Construction
[0079] The technical solutions and beneficial effects of the present invention will be described in detail below with reference to the accompanying drawings.
[0080] like figure 1 As shown, the present invention provides a method for optimizing and guiding an aircraft level change procedure, comprising the following steps:
[0081] Step 1, the crew selects the aircraft to change the target altitude and the reference target aircraft, and submits an application for the change of altitude to the controller, and prepares to execute the altitude change procedure after obtaining the approval;
[0082] Step 2, build the weather model, particle model and performance model required for the aircraft to change the altitude;
[0083] In the above step 2, the construction method of the meteorological model is:
[0084] 1a, according to the temperature deviation and barometric altitude, determine the atmospheric temperature T:
[0085] T=T 0 +ΔT+β T ·H p
[0086] Among them, T 0 =2...

The invention discloses a method for optimizing and guiding an aircraft level change procedure (IN-TRAIL PROCEDURE, ITP). Then prepare to execute the level change procedure; build the weather model, particle model and performance model required for the aircraft level change; plan the aircraft level change guidance procedure with the goal of the shortest time; plan the aircraft level change with the goal of the least fuel consumption Guidance program: output the altitude guidance profiles of the two change methods to the crew ITP equipment, the crew selects the change method according to the purpose of the change, and loads it into the flight management system for automatic execution. This method takes into account the reasons for the flight crew to request an altitude change, solves the defect that the current ITP concept cannot reflect the flight crew's need to change the altitude, and improves the intelligence and economy of aircraft operation.
Description
technical field [0001] The invention belongs to the field of civil aircraft avionics, relates to the fields of airborne monitoring, cockpit display and the like, in particular to a method for optimizing and guiding an aircraft altitude change procedure. Background technique [0002] The IN-TRAIL PROCEDURE (ITP) is a new application under the ADS-B IN surveillance technology, which acts on the cruise phase in oceanic and remote areas. When the crew needs to cross the altitude, it will receive and process the ADS-B signal of the aircraft in the surrounding airspace, select one or two aircraft as the reference aircraft under certain criteria, and submit the altitude change request of its own aircraft to the controller. , and then complete the height level change procedure. The ITP operation can assist the crew to achieve the goal of effectively reducing fuel consumption and improving flight safety and flight efficiency on the premise of ensuring a safe flight interval.
