Abstract: The total system error (TSE) reflects that the lateral track deviation of performance-based naviga-tion (PBN) is mainly flight technical error (FTE). In order to ensure the operation safety of PBN, this paper first introduces the control and constraint of flight technical error (FTE), and then analyzes the influencing factors and characteristics of flight technical error from three aspects of human factors, atmospheric environment and aircraft performance. Human factors are caused by pilots' subjective factors, mainly including pilots' attention distribution, flight technology, flight strategy, etc., which are important components to control flight technical errors. In PBN operation, real-time monitoring of flight technical error should be carried out to reduce the influence of human factors on flight technical error, so as to ensure the track tracking and maintenance ability in flight.
