Troubleshooting as a Mechanism of Motion of Functionable System through MIRCE Functionability Filed

Dr Jezdimir Knezevic, The MIRCE Akademy, Woodbury Park, Exeter, EX5 1JJ, UK

The purpose of a paper is to address the troubleshooting, an activity performed by maintainers to identify failed component or module, as a mechanism of the motion of a functionable system through the MIRCE Functionability Field. For effective maintenance troubleshooting, as one of the main drivers of the “speed” of moving through negative functionability state, is essential element of any corrective maintenance task. To successfully perform troubleshooting tasks maintainers must possess both the knowledge and skills to find and fix problems efficiently.  Many years of research have demonstrated that it is much easier to and learn manual skills than troubleshooting skills. The paper clearly demonstrates that troubleshooting is a complex subject as it is driven by both sides of equation, namely system designers that conceive troubleshooting processes and maintenance managers that manage them during the in-service life of functionable systems.

Impact of High Altitude Ultraviolet Radiation on Functionability of Flight Crews

Dr Jezdimir Knezevic, MIRCE Akademy, Woodbury Park, Exeter, UK

The philosophy of MIRCE Science is based on the premise that the purpose for the existence of any functionable system is to do functionability work. The work is done when the expected measurable function is performed through time. In MIRCE Science a flight crew is considered as an element of a flying system type. MIRCE Mechanics is a part of MIRCE Science that focuses on the scientific understanding of the mechanisms of the interactions between functionability elements and the consequences on functionability performance.  The research performed shown that pilots and flight crews on aircraft is twice as likely as the general population to develop life-threatening melanoma skin cancer. On average, those who developed melanoma were 42% more likely to die compared with the general population. With progress in aviation technology, aircraft will fly longer and at higher altitudes attracting more and more passengers demanding more and more flights.  Hence, the main objective of this paper is to investigate the mechanism of interactions between the high altitude ultraviolet radiation on functionability of flight crew.

Fireless, Burning Smell Driven, Mayday Landings of Commercial Aircraft as a Mechanisms of Motion in MIRCE Mechanics

Dr J. Knezevic,  MIRCE Akademy, Woodbury Park, Exeter, UK

According to Knezevic the purpose for the existence of any functionable system  is to do functionability work. The work is done when the expected measurable function is performed through time. [1] However, experience teaches us that expected work is frequently beset by the occurrences of undesirable interruptions like component failures, natural phenomena or human actions, some of which result in hazardous consequences. MIRCE Mechanics is a body of knowledge that focuses on the scientific understanding and description of the mechanisms that generate undesirable in-service interruptions. Thus, the main objective of this paper is to examine the mechanism that generated undesirable in-service interruption to 32 flights, on 16th October 2017, within UK airspace. After fireless burning smoke/fumes were felt in their cockpits the flight crew went to oxygen and declared either a PAN-PAN or a MAYDAY landing. The first event took place around 0622 during departure from Liverpool causing the aircraft to declare mayday landing and return back to land. It was followed by clusters of affected aircraft in the Channel Islands, Liverpool, Manchester and London, later in the day. Although this is one of an extremely rear observed event, its mechanism had to be understood, as if repeated, it will generate the motion of an aircraft through MIRCE Functionability Field and impact its functionability work done and resources consumed. Inspections of aircraft involved and the analysis of the meteorological conditions in Europe have revealed that the burning smell did not  result from a failure of any component, but it was as a result of smoke and dust carried in the atmosphere from North Africa and Iberia. Satellite imagery from the European Organisation for the Exploitation of Meteorological Satellites  (EUMETSAT) verified this theory. Potencial actions for reducing the impact of this functionability mechanism are presented. (read more)

Emergency Oxygen Provision as a Mechanism of the Motion of an Aircraft Through MIRCE Functionability Field

Dr J. Knezevic, MIRCE Akademy, Woodbury Park, Exeter, UK

MIRCE Mechanics is the discipline of MIRCE Science that focuses on the scientific understanding and description of the functionability actions that govern the motion of functionable system types though the MIRCE Functionability Field (MFF) [1]. A full understanding of the mechanisms of these actions is essential for the accurate predictions of the functionability performance of functionable system types using MIRCE Functionability Equation. Thus, the main objective of this paper is to address a provisioning of emergency oxygen as a mechanism of a motion of an aircraft through MFF generated by the observed physical phenomena or human activities. Some of them are briefly described and analysed in the paper.  Based on the evidence available recommendations for the reduction of the probability of occurrence of negative functionability events of the emergency oxygen provision are presented.

Glare as a Mechanism of the Motion of an Aircraft through the MIRCE Functionability Field

Dr Jezdimir Knezevic, MIRCE Akademy, Exeter, UK

Abstract: MIRCE Mechanics is the discipline of MIRCE Science that focuses on the scientific understanding and description of the phenomena that govern the motion of functionable system types though the MIRCE Functionability field [1]. A full understanding of the mechanisms that generate the motion is essential for the accurate predictions of the functionability performance of functionable system type.  According to the 2nd Axiom of MIRCE Science the motion of a functionable system type through MIRCE Space is a result of imposed natural phenomena or human activities, which are jointly called functionability actions. Thus, the main objective of this paper is to address glare as an observed physical phenomenon in aviation that can contribute to fatigue, due to the frequency with which the pilot’s eyes must adapt from cockpit to exterior, from near to far, from dark to light. Although it is not a frequently manifested catastrophic event, direct or reflected glare is a physically observable phenomenon, which has been attributed to impact directly on the performance of humans involved in flying aircraft and operating them on the ground.  The paper also presents a set of possible preventions and management actions that could be taken to reduce the consequences of glare on the safety of flying.(read more)

Pitot Tube Blockage by Mud-dauber Wasp as a Mechanismof a Motion of an Aircraft through MIRCE Functionability Field

Dr Jezdimir Knezevic, MIRCE Akademy, Exeter, UK

Abstract: MIRCE Mechanics is the discipline of MIRCE Science that focuses on the scientific understanding and description of the phenomena that govern the motion of functionable system types though the MIRCE Functionability field [1]. A full understanding of the mechanisms that generate the motion is essential for the accurate predictions of the functionability performance of functionable system types using MIRCE Science. According to the 2nd Axiom of MIRCE Science the motion of a functionable system type through MIRCE Space is a result of imposed natural phenomena or human activities, which are jointly called functionability actions. Thus, the main objective of this paper is to address pitot tube blockage by mud-dauber wasps as a mechanism that influences the motion of an aircraft through the MIRCE Functionability Field. Although it is not a frequent and globally realised phenomenon, it is a physically observable one, which is experienced by aircraft on the ground in areas where these types of insects are present. The paper also presents a set of a possible prevention and management actions regarding this specific phenomena. (read more)
