An Introduction of China National FOQA Program CAST 2017-04-24
Why we do? To enhance predictive safety management, flight quality monitoring serves as a vital method for safety assurance, which has won wide recognition among the world aviation industry. CAAC began to sponsor research on FOQA techniques in 1993 Implementation of FOQA project in 1997
Why we do? CAAC issued Regulations on FOQA Management in 2000 CAAC issued civil aviation safety directive to implement industry standards of FOQA items for Airbus and Boeing aircrafts in 2007 CAAC issued CCAR-121-R4 in 2010 CAAC issued AC for FOQA in 2012
Why we do? Safety challenge must be faced The continuous rapid growth of China Civil Aviation The limited management resources A/C No. will be 3000 2016 Turnover : 95.9 Billion- TonKm, growth Rate >12% VS. Inspectors Safety Information Tools
Why we do? Problem must be solved Less use data Only FOQA individually No safety trend analysis based on industrial data No information platform sharing CAAC Airlines
Why we do? New technology should be used WQAR Advanced communication, network and computer Technology Big data analysis WQAR Communi cation Network Computer Airlines A Airlines C Airlines B Airlines D
China National FOQA Program Our Goal: CAAC FOQA Station will provide data support to improve CAAC safety policies, standards and regulations by analysis of technical trends, case study and other study.
China National FOQA Program National FOQA Program WQAR Installation CAAC FOQA Station
WQAR Installation WQAR installation is required for all aircrafts operated in CCAR 121 from 2017 It is encouraged to update WQAR from 2G to 3G cellular CAAC provides national financial support to airlines before July 31, 2017
WQAR Installation CCAR-121 Commercial Airlines:49 Commercial aircraft:2990 More than 10000 flights per day Volume of QAR data is closed to 80TB/year

2. 数据分析应用场景设计 CAAC FOQA Station Reports: Daily report: Red class exceedance from 08:00 (-1 day) to 08:00 Special risk report: released on demand Event report: such as Tail Strike, Engine Fire, etc. Seasonal report Research report: such as GPWS, Dual Input, etc.
CAAC FOQA Station Red Exceedance Analysis From Nov,2016 to Feb,2017 81 Red Event was detected. The Main is: TCAS RA Warning: 49 Pitch High Takeoff: 5 RTO: 4 GPWS Pull Up: 4
