This project is about a study to investigate factors and essential elements in developing and managing airspace safely and efficiently. International Civil Aviation Organization (ICAO) had reported accidents and incidents involving aircraft since 2010. In 2018, ICAO stated that states did not have adequate procedure to monitor safety standards, resulting in higher risk. ICAO has identified problems relating to accidents and incidents which must be rectified. ICAO has also specified that every state is required to have a policy to manage airspace to cope with increased number of aircraft. This is to reduce any loss from air transport as much as possible. Thailand has a monitoring system under the Universal Safety Oversight Audit Program (USOAP-ICAO) in compliance with ICAO standards by overseeing all essential points relating to the Civil Aviation Decree 2015. It is of great importance that the decree is followed to provide support and improvement in safety standards in general. Prior to the emergence of Covid-19, every country including Thailand experienced a continuous increase of flights, leading to several delays for departures and arrivals. Both Suvarnabhumi and Don Mueang Airports were particularly affected with more incidents reported concerning safety issues. Air Transport is vital for every country, and it is expected that there is going to be a return to an increase in air traffic soon along with the blueprint for the development of air transport in the next 15 years. It is the intention of the researchers to study important elements in managing air space safely and efficiently, using qualitative and quantitative methods. Information was obtained from professionals in aviation such as airline pilots, domestic and international, aviation service providers including air traffic providers and engineers. This study includes data at national and international levels. An important part of this study is the use of Factors Analysis. This study discovered that:
1. Communication in aviation is an important variable in providing service and management for all air traffic as well as distributing information and aviation news.
2. Navigation System is important for providing information, developing, and managing air space, using aircraft with new technology in accordance with ICAO plan for managing flights at present.
3. Surveillance is required for aircraft flying in areas which cannot be followed such as runway and aircraft approaching each other in areas with high terrains.
4. Air Traffic Management System is essential for designing procedures for take-off and landing procedures, applying new technology, ‘Performance Based Navigation’ and data base for geography and obstacles.
The analysis from this study, using simulation which significantly affects the air space with maximum safety and efficiency include Aviation Communication, Air Traffic Service System, Navigation System and Surveillance respectively.
