## Chapter 2 Overview of Current Air Traffic Safety Measures

## 1 Conversion to Comprehensive Safety Management

## ☐ Introduction of State Safety Program (SSP)

Requested by the annexes to the Convention on International Civil Aviation which were revised in November 2010, the consideration of the establishment by the end of 2013 of the State Safety Program in the field of aviation with oversight safety degree indicators usage, focusing supervision on particularly unsafe elements, implementing Safety management training safety management training for operation businesses (air transport service operators, Airport operators, air traffic services implementers) is promoted.

## 2 Development of air traffic environment

## ○ Measures Against Runway Incursion

In order to prevent the reoccurrence of runway incursion trouble, counseling was received from external experts and countermeasures are promoted to cover the prevention of inconsistency between the guidance manual concerning control terminology for air traffic control and pilots, and pilot communication with air traffic control. The measures also deal with the “tangible” and “intangible” sides of improving systems that visually show and transmit the runway occupancy condition to air traffic control or the pilot.

## ☐ Promotion of prevention of bird strikes to aircraft

Bird strike Prevention Measures Review Committee consisting of the experts on the bird ecology and airline carriers held a study group considering the analysis and countermeasures of bird strikes. In fiscal year 2011, as a new measure, a bird strike database information was created to start sharing information among the bird-strike relevant parties. In addition, in order to develop a control method according to the ecology, for cases when an unknown type of bird crashes, the bird-type specification by DNA / feather by expert opinion is being promoted. Furthermore, at Tokyo International Airport bird sensing devices (such as bird detection radars) were introduced in order to promote the strengthening of the surveillance of avian ecology.

## 3 Ensuring Safe Operation of Aircraft

## ☐ Strengthening of Supervision of air carriers

Important check points were decided for every airline company, and along with frequently implementing technical and moreover systematical inspection of premises from a full-time examination structure, effective safety audits were implemented for airline companies such as expeditious premise inspections in cases of occurrence of trouble involving safety had occurred.

## ○ Implementation and Strengthening of the Transport Safety Management System

Based on the “Transport Safety Management System” introduced in October 2006, a safety management system was established by the operators, which was taken action for unification by management executives to on-the-site workers as a whole. The country carried out the evaluation for transport safety management to 87 companies by the end of December 2011 to confirm the status of implementation.

## 4 Ensuring Aircraft Safety

## ○ Improvement of Technical Standards of Maintenance and Examination of Aircraft

In order further to improve the safety of the aircraft, the information obtained from foreign governments to contribute to research and technology for aviation safety is collected and analyzed, in addition to providing information, which needed for aircraft operations, technical standards on the safety of aircraft and equipment on the basis of such information have been developed.
