Aircraft Life Cycle and Development Flashcards
leisure traveler
price sensitive, check in 3 hrs before, baggage, in-flight entertainment, comfort less important
business traveler
flexibility > ticket price, quick check in, lot of hand baggage, in-flight communication, comfort and service top priority
six traveler tribes of the future
simplicity searchers, cultural purists, social capital seekers, reward hunters, obligation meeters, ethical travelers
simplicity searchers
ease, transparency, outsourcing decision making
cultural purists
unfamiliar culture, new way of living
social capital seekers
max social reward, exploit potential of digital media
reward hunters
busy lives, seek ROI, indulgent experiences
obligation meeters
business, need to be in place and time without fail
ethical travelers
environmentally concerned, high awareness on local economy
green responsibilities
eco-ethical concerns will be a feature of the future consumer landscape
work-life compounds
broad casualization of business practices and arrangements
option shock
leads to bundles
enterprise networking
online networking more important now than ever before
peer power
social media boosted brand loyalty
narrative data
big data personalizing services
pricing gets personal
perfect price discrimination - new tourist groups
Aircraft life cycle
genesis, design, development, production, modifications, product support, disposal
airplane development process
research, specification, conceptual design, preliminary design, detail design, flight test, operations, growth versions
aircraft design
requirements, conceptual design, preliminary design, detail design, fabrication
enabling technologies for airplane concept
aerodynamics, propulsion, flight and load control, airborne systems, structural concepts, materials/manufacturing
aircraft commonality
airline typically wants same propulsion system, flight deck, components, and sub systems, does not affect direct operating costs
v-model requirements engineering
consumer requirements - component level design requirements - critical design review - components - assemblies - system - end product
validation
process of confirming that requirements for a specific intended use have been fulfilled
verification
iterative process during design stage to make sure requirements are fulfilled
aircraft conceptual design
mission analysis, initial sizing (overall weight), parametric sizing (optimal engine thrust and wing area), constraint diagram, configuration options, weight estimation
costs
marketing, systems engineering, design, production, operations
economic end of life
operating cost exceeds revenue capacity, availability of significantly more efficient aircraft, environmental regulations make operations less acceptable
structural end of life
repair of the structure is no longer economically feasible, overall fatigue life usually twice as long as the minimum designed service life
aircraft residual value
age, operational history, production cycle, manufacturer status, market condition, environmental regulations
cost estimation relation(CER)
costs = a*(P^x)
a - system specific constant, P - independent const driving parameter, x - system specific sensitivity factor
degression factors
factor of the technological state of the art, technical quality factor, experience related factor, learning factor in production
man-year
enables cost estimations independent of time related influences, inflation, different companies, different countries, different currencies, exchange rate fluctuations
development costs
unrealistic (used to sell concept), minimum credible (used to win a call for tenders), ideal or theoretical (assuming everything goes to plan), realistic (including some uncertainty), effective costs until end of development (overall costs after development)
production costs
in increasing order, materials, manufacturing, direct services and support, technical assistance and support
