Operation of the aircraft systems

 

 

 

ï‚· To understand the principle, the function and layout of an Avionics system in aircraft applications
(Commercial, Business or Military aircraft).
ï‚· To discuss advantages and disadvantages by examining the components, system layout and
operation of avionic systems to develop the skills, competencies and knowledge necessary to
investigate and analyse interrelated aircraft and complex avionics systems.

Task:
You are required to:
a. Identify and investigateProvide, following investigation and analysis, a suitable aircraft functional
Ground Proximity Warning System (GPWS) Block Schematic diagram for a Commercial or Military aircraft
(one of which you have used as a training platform during practical sessions at MTC). This may be in the
form of a hand drawn labelled diagram or an extract from an Aircraft Maintenance Manual (AMM) or
publication.
b. Interpret and articulate through critical analysis,Describe the operation of the aircraft GPWS which
you have identified and drawn with and the function of it’s components within the system.
c. Through research, assess and recognise Examine and summarise the use of GPWS and Enhanced
Ground Proximity Warning System (EGPWS) aligned with in the aircraft operation highlighting the Safety
factors, advantages and disadvantages.
d. As a case study examine and summarise the findings of an Air Accident Investigation with focus on
investigate an example of confusion arising from mismanagement of GPWS information which had serious
or potentially serious consequences for an aeroplane operation highlighting the; Human, safety and
engineering practice factors contributing to the accident in the aviation history.
Background:
A Terrain Avoidance and Warning System (TAWS) is a safety net that automatically provides a distinctive
warning to pilots when the aeroplane is in potentially hazardous proximity to terrain. The first
implementation of TAWS was Ground Proximity Warning System (GPWS) and was introduced in the 1970s
as a means to combat the high incidence of ControledControlled Flight in to terrain (CFIT) accidents and
near-accidents.
Equipment:
AircratAircraft in workshop 17, Relevant Aircraft Maintenance Manual (AMM), Wiring Diagram Manual
(WDM).
Procedure:
You are required to investigate, analyse describe and discuss the areas identified. You are referred to the
Equipment/Resources, in addition to the Reading/References section of this assignment brief.
You will write a technical report (1,500 words) on this subject taking into consideration the following key
features:
ï‚· Format a Cover page and Table Of Contents
ï‚· Describe the purpose of your report in an Introduction.
ï‚· Provide a Block Schematic of an Ground Proximity Warning System (GPWS)
ï‚· Describe the operation of the Ground Proximity Warning System (GPWS) and the function of the
components
ï‚· Discuss GPWS and Enhanced Ground Proximity Warning System (EGPWS) highlighting the Safety
factors, advantages and disadvantages.
ï‚· Investigate an example of confusion arising from mismanagement of GPWS information which had
serious or potentially serious consequences for an aeroplane operation in the aviation history.

ï‚· Summarise your findings in your report with a conclusion
ï‚· Include a Bibliography to list your supporting references
ï‚· Correctly use an Appendix for supporting data and information (If required)

Sample Solution

security. The issue with the broader view of human security is that it often refers to threats already identified in human rights law instead of acknowledging new threats, state duties or remedies to human insecurity. The narrower view of human security may thus provide for better understanding in identifying new or more severe threats aimed at focusing on every individual. A narrower view of human security was proposed in the 1994 United Nations Development Programme (UNDP) which identified universal threats to human wellbeing. There are essentially seven issues associated with human security: economic security, food security, health security, environmental security, physical security, community security, political security (United Nations Development Programme, 1994). The UNDP identified not only individual threats, but collective threats that are not direct human rights abuses, such as climate change but affect the lives of many individuals (ibid). Human security thus adds to human rights law and establishes a framework of analysis for states and international organisations to ensure the promotion of human rights and democratic values through new actions such as the Responsibility to Protect Doctrine (R2P). This doctrine attempts to legitimise and normalise international intervention when states are unable or unwilling to protect its own citizens (Howard-Hassman, 2012). R2P suggests that sovereignty is not a right, but instead demands states to provide protection and security to their citizens. Even when states have ratified human rights instruments it does not mean they are to prioritise one right over another right. Human security aims to ensure that states do not abuse this power and instead makes sure that all rights of the individual, no matter how trivial, are protected. This is an important element of political science as often law is considered to be the biggest protector of human rights. It further unites diverse states, agencies and NGOs who aim at safeguarding citizens’ rights under international law without having to resort to force. This has proved successful in a many UN peacekeeping operation including Cambodia, El Salvador and Guatemala whereby basic security has helped end conflicts and the destabilisation of many states (United Nations Peacekeeping, n.d.). The narrow view of human security, therefore, advances human rights law as it provides concrete objectives and offers a framework of analysis that directly helps in promoting human rights standards and take new actions to counter new threats. Although human security aims at promoting and protecting individual rights, particularly when states are unwilling or unable to do so, there are criticisms it faces in regard to the extent to which these rights are actually protected. Howard-Hassman (2012) has argued that the human security discourse has the potential
