chapter 3 the icao and the Civil Aviation Authorities
Airworthiness (Third Edition)#R##N#An Introduction to Aircraft Certification and Operations, 2016Co-Authors: Filippo De FlorioAbstract:Aviation safety and Civil Aviation rules are the result of adapting and developing rules and organisation structures originally related to marine traffic. A fundamental milestone in this direction was in 1944, the Convention on International Civil Aviation (also known as the Chicago Convention), followed in 1947 by the constitution of International Civil Aviation Organization (ICAO) as a specialised agency of the United Nations, originally created to promote the safe and efficient development of Civil Aviation. This chapter describes the 18 (now 19) ICAO Annexes, which are the basis for the international aeronautical requirements, with a particular focus on the annexes at the basis of all airworthiness requirements. This chapter also presents the structure of the most relevant airworthiness Authorities, the Federal Aviation Administration and the European Aviation Safety Agency, with some historical notes on the Joint Aviation Authorities.

validation of the fall3d ash dispersion model using observations of the 2010 eyjafjallajokull volcanic ash clouds
Atmospheric Environment, 2012Co-Authors: Arnau Folch, Antonio Costa, Sara BasartAbstract:Abstract During April–May 2010 volcanic ash clouds from the Icelandic Eyjafjallajokull volcano reached Europe causing an unprecedented disruption of the EUR/NAT region airspace. Civil Aviation Authorities banned all flight operations because of the threat posed by volcanic ash to modern turbine aircraft. New quantitative airborne ash mass concentration thresholds, still under discussion, were adopted for discerning regions contaminated by ash. This has implications for ash dispersal models routinely used to forecast the evolution of ash clouds. In this new context, quantitative model validation and assessment of the accuracies of current state-of-the-art models is of paramount importance. The passage of volcanic ash clouds over central Europe, a territory hosting a dense network of meteorological and air quality observatories, generated a quantity of observations unusual for volcanic clouds. From the ground, the cloud was observed by aerosol lidars, lidar ceilometers, sun photometers, other remote-sensing instruments and in-situ collectors. From the air, sondes and multiple aircraft measurements also took extremely valuable in-situ and remote-sensing measurements. These measurements constitute an excellent database for model validation. Here we validate the FALL3D ash dispersal model by comparing model results with ground and airplane-based measurements obtained during the initial 14–23 April 2010 Eyjafjallajokull explosive phase. We run the model at high spatial resolution using as input hourly-averaged observed heights of the eruption column and the total grain size distribution reconstructed from field observations. Model results are then compared against remote ground-based and in-situ aircraft-based measurements, including lidar ceilometers from the German Meteorological Service, aerosol lidars and sun photometers from EARLINET and AERONET networks, and flight missions of the German DLR Falcon aircraft. We find good quantitative agreement, with an error similar to the spread in the observations (however depending on the method used to estimate mass eruption rate) for both airborne and ground mass concentration. Such verification results help us understand and constrain the accuracy and reliability of ash transport models and it is of enormous relevance for designing future operational mitigation strategies at Volcanic Ash Advisory Centers.
