Mission Statement
 To create an innovative and cost effective
commercial aircraft capable of take-off and
landing in extremely short distances, making
it available to a larger number of runways, in
order to open up more airports, primarily to
relieve the continuous growing congestion of
large hubs.
3
“Next-Generation DC-3”
 An aircraft that is going to see very large
scale production to fill a popular and
profitable niche in the market
 One that is going to revolutionize air travel
4
Market Outlook


Economic growth yielding traffic growth.
Domestic fleet average seat size growth is dramatic.
5
Market Outlook



17,650 new single aisle airplanes
will be delivered over the next
20 years.
This will make up 48% of the total
airplanes in service in 2026.
By the year of 2058, 61,604 single
aisle airplane will be in service.

Primary Customer: Airlines
 Currently, over 20% of all flights from O’Hare, LaGuardia, &
Newark are Delayed
– Bureau of Transportation Statistics
source: U.S. Department of Transportation - Federal Aviation Administration
 Customer Needs
–Carry out short, mid-range missions
–Reduced flight delays
–Low cost
 Proposed missions include flights
from Gary Chicago to Dallas Love Field, …693 nmi
7
Customer Benefits

“Flight delays cost the U.S. economy $15 billion a year”
Mary E. Peters, United States Transportation Secretary, January 22nd, 2008
 Maximize profits
– Maximize Total Revenue
 Reduce flight delays through direct flights to secondary
airports
 More flight services and availabilities increase the
revenue for airlines.
–Reduce Costs
 Operation cost
– Less idle time saves
aircraft fuel burn.

Competitors
 Types of Transportation
– Automobiles
– Airplanes
– Trains
– Personal aircraft/ Skycars
 Airplane Manufactures
– Range 1500-2000 nmi
– 150-170 passenger capacity
– Single isle
9
Airplane Manufacturers
 Aircraft within our size and
range requirements
– single aisle planes
 Competition includes
– N generation Boeing 737NG
family and its replacement, the
737RS (Y1)
– the Airbus A320 series and its
replacement (NSR)
– Embraer’s E-Jets (spec. E-190
and E-195)

Airplane Manufacturers
 ARrival looked at aircraft
within our size and range
requirements (e.g. single
aisle planes)
 Competition includes the N
generation Boeing 737NG
family, the Airbus A320
series, Embraer’s E-Jets
(spec. E-190 and E-195),
and the N+1 generation
C110 and C130 CSeries
jets from Bombardier
(Canadair)
11
Other Competitors
 Personal Air Vehicles
– The Skycar
– Family Commuters
12
Why High-Speed Trains are Not
a Competitor
 Too Expensive
– Portugal estimates that the high speed rail line "connecting Lisbon
with Madrid and with Porto, due to be operational by 2013, is
estimated to cost around 7.2 billion Euros”, according to Forbes.
Compare the costs to the new international airport near Lisbon,
estimated at 3 billion Euros, and you can see why people are
questioning the need.

New Technologies
 Advanced materials such as
CFRP which give a projected
weight reduction of about
15% over N generation
competitors from Airbus and
Boeing and 13% over
Embraer’s E-Jets*
 Advances in propulsion such
as the geared turbofan (GTF)
and the Unducted Fan (UDF)
for fuel efficiency and noise
reduction
 High lift through blown flaps,
potential use of thrust
vectoring
 Benchmarking with the
EasyJet “EcoJet” concept for
“Green” technologies
*Based off of Boeing 787 weight savings
vs. its competitors

Assuming the 787’s CFRP construction becomes the industry standard,
ARrival applied the weight saving factor of the 787’s design over its peers
to current generation Boeing and Airbus single aisle jets.
27
Benchmarking
 Based off of ARrival’s projected requirements and the data
from our main competitors, ARrival found the competitors
that closely matched our aircraft’s preliminary
specifications
 Weight savings data from Boeing 787 family over the 767
family, 777 family, and Airbus A330 family used to project
weight savings of a CFRP single-aisle plane vs. the
737NG, A320 family, and the larger Embraer E-Jets
 Bombardier CSeries aircraft match our projected range
requirements however, data for this type is sketchy as it is
an N+1 generation aircraft still in planning
