ATCs continues to be a family of friends with a common interest - making and trading ART so let’s be supportive of each other and also keep our posts positive and informative.As we continue to grow as a group, our artistic interests will continue to grow with the current trends. We encourage everyone to “STEP OUTSIDE THE BOX” and learn by experience, but most importantly we want everyone to have fun.No cross posting of swaps will be allowed.Public bashing or flaming of others work will not be tolerated any offenders will be immediately banned from the group.This is a busy swap oriented group and e-mail might be heavy at times. 771 likes 26 talking about this 25 were here. ATCS is a Technology Consulting firm providing services in the area of Enterprise IT, Digital Transformation, Data.The group is about trading Artist Trading Cards (a 2 1/2" x 3 1/2" piece of art) as well as other mixed media (tags, books, jars, postcards, etc) art.ATCs, which stands for Artist Trading Creations, is a good place to connect with individuals who love making and trading art, so ACTIVE PARTICIPATION is EXPECTED.Determined and stochastic risks are especially important in this process. These decisions occur and are implemented in both clear and stealth forms being influenced a lot. Air traffic controllers’ (ATCs) work process can be presented as uninterrupted set of decisions.
Atcs Group Professional Mistakes SetUsing paired comparison, normative part of summary hazard and differentiating part of summary hazard, the preferences system of air traffic controllers is received. Air traffic controllers’ preferences system (PS) is discussed in regard to typical professional mistakes set. This seamlessly integrates in ICAO safety paradigm.![]() Survey procedure influenced positively on the ability of mistakes memorization, recognition, and avoidance during simulation training.As for today human factor (HF) has approved dual influence on flight safety (FS). It increased Kendall rank coefficient value up to Wproposed = 0.7. Multistep procedure of marginal opinions separation is implemented. The significance level for all cases is equal to 1%. Proposed Kendall rank coefficient outweighs the traditional one twice (Wtraditional = 0.2722, Wproposed = 0.55237). Systems pair has high correlation level according to Spearman coefficient (R = 0.9727). These factors could be classified as external/internal, biased/unbiased, stochastic and deterministic, etc. They are generated and implemented in clear and stealth forms under the influence of various factors. It is natural that all kinds of such generalization should be scientifically based.Frontline air operators (in this chapter we talk only about air traffic controllers (ATCs)) work process can be presented as uninterrupted set of decisions. They are based on the reports and proceedings of air companies and regional administrations dedicated to negative HF influence prevention. This stimulated ICAO to publish multiple circulars, annexes, and manuals with generalized world experience on the topic. ![]() They could be used for ATC attitude identification toward hazards of typical errors and mistakes with ranking method :Sorting is used in case of previous clustering of huge number of alternate options. The latter two grow during professional activity process.There are several most common ways to determine PS. On the other hand, such knowledge might contribute revealing of flaws in professional training and conceptual safety model. Each of them has significant real occupational experience including nonstandard situation solving. However participants encouraged to pass the survey are highly experienced ATC. At that point the proposed list of typical mistakes was also partially based on the ICAO recommendations.This set of mistakes significantly exceeds operative capabilities of human memory expressed with “magic Miller’s number” (7☒ units at the same time) and reaches the so-called Parkinson’s inefficiency coefficient. ![]() They use their own professional experience and statistics of accidents and incidents. All presented is a part of wide class of experts’ opinions explication methods where expert opinion is taken as basic undividable statement.Preferences c ij value sequence determination as quantitative characteristics of mistakes comparison is the following:Experts express their statements via pair comparisons of mistakes hazards. This pushes expert’s attitude to other mistakes out of the single comparison scope. J.Proposed method of PS calculation is quite simple since researched mistakes are compared in pairs. J in regard to hazard level and z is the index that describes summary hazard level of mistakes Er. Pokemon 3d romsIf they match, then the task of z index determination is successfully solved. It is compared to the empiric coefficient of the same kind K p. Actual coefficient of mistakes hazard level ratio K A is calculated. With iterative priority arrangement method (PAM) , the values of mistakes hazards priorities C i(k) are found.6. These estimations are saved as ranked set boundary components ratio.C = c 11 c 12 ⋯ c 1 j ⋯ c 1 n c 21 c 22 ⋯ c 2 j ⋯ c 2 n ⋮ ⋯ ⋮ ⋮ ⋯ ⋮ c i 1 c i 2 ⋯ c ij ⋯ c in ⋮ ⋯ ⋮ ⋮ ⋯ ⋮ c n 1 c n 2 ⋯ c nj ⋯ c nn. PAM with z coefficients can be used for that purpose. If it is possible to estimate mistakes ratio, then they should be arranged to define boundary elements of their whole set. It is the estimation of boundary mistakes hazard ratio empiric coefficient K p. This happens when certain mistakes make no difference in ATC expert opinions, thus receiving “average” ranks. If pair comparison systems are non-transitive or possess equality (indifference), the z values procedure calculation should be changed in a proper way. Thus it should be paid more attention.
