In certain situations, non-compliance with ICAO regulations cannot be avoided. Aeronautical studies are therefore necessary to ensure that the safety of flight operations has not been compromised.
An aeronautical study is an analysis and assessment of the safety of all flight operations at an aerodrome in relation to other operational processes. It consists of following steps :

  • System description
  • Hazard analysis
  • Risk analysis
  • Combined overall assessment of contributing risk factors and possible solutions

 

 

 

 

Aeronautical Studies consider all associated factors, including traffic volume, Orientation, airspace, weather, airport configuration, surface Movements and the use of the service by operators. The type of studies can require only minor adjustments or it can be required to an examination of the impacts of replacing an airport control service with another form of service, introducing a new service, or terminating a service completely. 
The Aeronautical Study process provides a systematic methodology for analyzing complex issues using a risk management approach. Risk analysis includes the identification of exposures to risk, and the identification and evaluation of alternative strategies for reducing or eliminating losses. Perception and communications issues that affect risk decisions are also fully assessed.

 

 

 

United ATS qualified team performs Aeronautical studies with the following methodologies :

  • Perform WGS- 84 survey for the Area of Study according to Data quality and integrity required by ICAO Doc.9674.
  • Evaluate Annex 14 OLS, Control of obstacles, shielding principles application and other consideration (ICAO Doc 9137 Part 6).
  • Evaluate Instrument and Visual Approach procedures and All PANS-OPS Procedures as per Criteria of ICAO Doc. 8168.
  • Evaluate the effect of Navigation Aids, Radar, and VHF reception.
  • Evaluation of effect on Aerodrome lightening and visual aids.
  • Analysis of Air traffic Flow (present and forecasted) and any operational consideration.
  • Evaluation and study of weather, climate, and environmental effects.
  • Provide Advisory Reregulation and/or amend Local aviation law if needed.
  • Consideration of any other ICAO standards and recommended practices.
  • Hazard Identification.
  • Risk analysis.
