Large data Age: Mining flight data value

The big data age has come.

Airlines also have a large amount of data, only flight data can contain Qar (Fast access Recorder) data, run the data and flight plan data, and so on, the data scale is huge. However, to master these huge data information is only the basis, the meaningful data will be specialized processing, mining its value to help airlines business decision-making purposes.

Since 2011, Shandong Airlines has attempted to integrate the flight data of Qar, operation and flight planning, and set up a comprehensive platform for comprehensive utilization of flight data. 2013, the construction of the system was completed. Mountain Airlines use the platform to monitor the use of temporary routes, reasonable arrangements for temporary routes. 2013, the annual shortened flight distance of 862,000 kilometers, save flight time 1276 hours, save 2870 tons of oil. The comprehensive utilization system, which is the product of the massive flight data produced by the flight, is a breakthrough in the use of flight data by airlines in the big Data era. This platform allows flight data to be successfully "Cross-border" from security to benefit.

Mining Qar data value

Comparatively speaking, the airline uses more data is the QAR data. Qar data is the airline's most valuable data asset, and it fully records the thousands of parameters of the aircraft during the flight. Therefore, the domestic airlines have invested a lot of money and energy for the installation and upgrade of QAR equipment and to carry out the application research of QAR translation data.

Since the 1970s, airlines in developed countries have been using Qar recorded flight data for flight quality monitoring, which has been more than 40 years old. In the safe operation, the Qar data played a huge role, the corresponding application is increasingly mature. Through the real, accurate, high-density records of airborne Qar data, it can fully reflect most of the conditions in the process of aircraft operation, through monitoring, inspection, can be nuanced to find pilots all irregular operation, and timely correction, so as to avoid the occurrence of flight accidents. The Qar data is helpful to improve the operation safety margin, carry out the forecast of running trend, and improve the flight technology of pilots.

And Qar data in the "benefit" aspect of the role, but it is entering the 21st century only gradually caused by domestic airlines attention. Of the Qar data in more than 1000 parameters, about 80 are closely related to the operational benefits of the flight. By decoding, collecting and processing these 80 parameters, the airline's valuable data wealth is formed. These data include engine fuel flow, APU fuel flow, APU use time, etc.

"At present, there are 260 flights per day, 380 flights, 740 flight hours, each year produces a 550G of mass Qar data." "The head of the Shan Hang Information department told reporters," in the past, the traditional production data statistics of airlines only include wheel-block flight hours, air flight hours, take-off and landing sorties, new refueling, original oil storage, retained oil, aviation fuel consumption, and so on, the statistics are relatively extensive, can not be accurate to each flight stage, also can not reflect the aircraft in the ground Through the effective utilization of the QAR data, we can sum up the law, find the problem, correct it in time, make the statistic analysis more detailed, break through the traditional statistical analysis method, and close to the front of the business, so as to achieve the goal of improving the control ability. ”

After the Qar data is refined, it will directly become visible "benefits". The mountain airlines actually already from the Qar data deep excavation application, tasted the sweetness.

In-depth

Open a new era of mass data application

For a long time, there are two major problems in the data utilization of mountain air Qar. One is the lack of powerful QAR data decoding analysis tool. With the rapid increase in the number of mountain fleet, as well as the new configuration of Qar equipment, the original system, whether in terms of function, efficiency and storage of large amount of data, are far from meeting the existing needs. Second, the Qar data source is isolated and can not be effectively integrated with other important data such as FOC (Operation Control Center), flight plan and ACARS (aircraft communication Addressing and reporting System).

For the integrated integration of Qar, FOC, flight plans and other data, and in-depth excavation of the use of QAR data, to enhance energy conservation and efficiency of mountain navigation management level, 2011, the establishment of the company by the shares of the Ministry of Finance to take the lead in the relevant departments of the flight data utilization System project team, With the Beijing voyage through the information technology company to promote the implementation of the system.

In data acquisition, the 65 aircraft had installed wireless Qar, and proposed in addition to CRJ models, all new imported aircraft must be installed wireless Qar. Wireless Qar power can be recorded, this advantage can help airlines have the air and ground of the complete data records, the formation of valuable data wealth. At present, 72 aircraft in the mountain, more than 90% of the aircraft have installed wireless QAR. In addition, the flight data decoding personnel insist on 24 hours a day on duty, timely detection of missing data, timely measures. If the wireless Qar data is missing, you can use the Qar data, FDR (flight data recorder) data to supplement.

Based on the comprehensive data, the flight data comprehensive utilization system is built by mountain navigation. The system is a data platform that fully utilizes the existing Data Resources Construction Foundation. Based on the QAR data and the flight plan data, the system realizes the precision monitoring function of flight plan, and realizes the function of spatial analysis, trend statistic and fuel time cost analysis with the integration of FOC operation control data, and integrates with ACARS data to make up the deficiency of the time data of the QAR data without switch hatch. The integrated data platform changes the isolation of data sources and provides a comprehensive data platform for Mountain Airlines.

The comprehensive utilization system of flight data integrates many kinds of data, provides the advantageous tool for grasping the flight production rule, and simultaneously monitors the flight production status, makes the mountain navigation in the industry front-end in decoding data utilization.

The integration of the data platform to build, so that mountain airlines into the flight production of a large number of data use a new stage.

Effectiveness

Initial economic benefit

Based on the trial operation and formal operation of the comprehensive utilization system of flight data in 2013, the comprehensive utilization system of flight data is of great value in detail management, spatial optimization statistics, computer precision monitoring and APM engine performance monitoring.

In particular, it is worth mentioning that the use of the platform to monitor temporary flight routes, reasonable arrangements for temporary routes, the whole year shorten the flight distance of 862,000 kilometers, save flight time 1276 hours, save 2870 tons of oil. The comprehensive utilization system of flight data has contributed to the improvement of airline economic benefits.

On the integrated platform of the comprehensive utilization system of flight data, the company does not simply divide the flight into several stages, like most airlines in China, instead, it divides the flight into more detailed 15 stages, including flying, starting, slipping, takeoff, takeoff, initial ascent, climb, cruise, descent, proximity, the least recent, Landing, landing slip-run, sliding into and over. The division of the 15 stages and its computing logic are at the forefront of the industry, which is helpful to the fine management of the airlines.

In the field of spatial optimization statistics, the system uses independent innovation algorithm to realize the automatic judgment and statistic of the temporary route, the correct rate can reach 92.4%, save the labor cost greatly, improve the work efficiency.

In the aspect of computer planning precision monitoring, the air consumption coefficient is adjusted by the mountain Airlines after analyzing the depth of the comprehensive utilization system of flight data. Only to adjust this data, Mountain Airlines Boeing 737-800 Fleet can save 2 million yuan per year for Mountain Airlines. In the field of APM aircraft engine performance monitoring, in the past, in the calculation of the planned refueling capacity, according to the actual refueling amount of additional consideration for 5% of the engine attenuation, and APM on-line, by calculating the engine performance attenuation of the impact of fuel consumption, can further accurate aircraft refueling capacity. Mountain Airlines adjusted the data to 2.5%, saving more than 500 tonnes a year. In the area of data statistics, QAR data Replacement Task Book Aviation Oil information can reduce task book input workload, temporary direct route use reduces the audit workload, greatly improve the work efficiency, replacement of staff efficiency.

The implementation of the comprehensive utilization system of the flight data of the mountain Airlines has accumulated valuable data wealth for the mountain airlines and brought economic benefits to the mountain airlines. More importantly, this platform provides us with accurate business support, which will help to achieve the goal of fine management in the end.
