Suitable aircraft functional Ground Proximity Warning System

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).

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:
 Format a Cover page and Table Of Contents
 Describe the purpose of your report in an Introduction.
 Provide a Block Schematic of an Ground Proximity Warning System (GPWS)
 Describe the operation of the Ground Proximity Warning System (GPWS) and the function of the
components
 Discuss GPWS and Enhanced Ground Proximity Warning System (EGPWS) highlighting the Safety
factors, advantages and disadvantages.
 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.
