HOW TO MEASURE AIRCRAFT TYPE CAPACITY? AN INNOCENT QUESTION WITH BIG CONSEQUE...DanielSALLIER
In this contribution I will introduce a new unit to measure aircraft type capacity. Aircraft type capacity is a quantity used in long term fleet forecast the type Airbus and Boeing are publishing every year or in long term forecast of movements by (generic) aircraft types the airports have to perform for future infrastructure dimensioning (terminals, aprons, stands, etc.). Aircraft capacity is downscaled at cabin level (1st, business class, etc.) leading to the contribution analysis of the different market segments to flights revenue/profit.
Aircraft type capacity has been stated in number of seats for ever. Unfortunately the seat count of an aircraft type is a very unsteady data to play with: airlines operate different seat counts even for the same aircraft type which keep changing all the time. Isn't it an inadequate unit leading to incorrect measurements which result in misleading analysis at the very origin of bad decisions?
To start with, we will have a critical look at how the aircraft type capacity is measured by the major players of the air transport industry. Then we will look at how cabin area could prove to be a far more adequate unit. Then we will question different ways of measuring it so that it can allow direct and consistent comparisons between different aircraft types. To finish with we will look at how seat counts and cabin areas can relate to each others and illustrate with an example how to reassess market segment income/profit contribution per flight.
Profit Maximization is addressing Multi-stop operating model of Airlines, it shows how to max. profit in terms of CASK and RASK analysis, delivering the best seniario to select the aircraft then the best result to operate the right segment
This virtual simulation program was developed to help airline management teams understand competitive market dynamics and improve problem solving and decision-making skills.

A Novel Approach To The Weight and Balance Calculation for The De Haviland Ca...CSCJournals
The main objective of this research is to provide companies operating different fleets of the De Havilland Canada Twin Otter DHC-6 seaplanes with an alternative method to the time-consuming Whizz Wheel procedure when calculating the weight and balance. Using this application, these operators can lower their aircraft turnaround, speed up the passenger boarding, dispatch the flights efficiently and save on fuel and dock expenses. Furthermore, this research shows how operators do their calculations currently and the positive impact of the application on their entire operation, including extra revenue generation amounting to $4M per year. Most DHC-6 seaplane operators are mainly in the Maldives. Therefore, this research was conducted while piloting these seaplanes and studying the day-to-day operations. While this paper presents the implementation of this software and its design model, it also discusses how two major operators used this application in the Maldives and one in St Vincent and the Grenadines.
Design and Fabrication of Blended Wing Bodyvivatechijri
Aircrafts are the widely used vehicle for rapid and long distance transportation. Although it is time
consuming, the conventional design of aircraft doesn't gives much space inside the aircraft and also consumes
more power because of its aerodynamic structure. Hence it is necessary to develop a new composite structural
design which overcomes these barriers. Blended Wing Body (BWB) is one of the solution of these problems. The
BWB configuration is a new concept in a aircraft design which provides greater internal volume, aerodynamics
and structural efficiency & noise reduction. The design approach of BWB is to maximize overall efficiency by
integrating the propulsion system, wings and the body into a single lifting surface. BWB is a unibody air craft
where the fuselage, wing and tail gets merged to form a single entity. The fuselage section of BWB is flattened
and has slightly airfoil shaped structure which exceeds the overall lift generation of aircraft. The objective of this
paper is to study aerodynamic study of Blended Wing Body. The project deals with the designing, analysing and
fabricating of UAV(Unmanned Aerial Vehicle) type electrically powered BWB aircraft system, and also selecting
appropriate propulsion system and other electric components
Today, most of the organizations quite advanced in involving multiple applications of strategic management.

The Race For The Future Of Aircraft SeatingTorben Haagh
The benefits of reducing the basic empty weight of commercial aircrafts are widespread and there for have become a high priority for airline manufactures. Any design that results in a reduced basic empty weight (BEW), or an overall reduction in weight of the aircraft will reduce the amount of fuel required to operate a commercial aircraft and thus the cost of fuel.

The Value of New-Technology Single-AislesCIT Group
Given the precipitous drop in oil prices, the value of new-technology aircraft has been questioned, but is this warranted? New-technology aircraft create revenue opportunities and reduce operating costs, enabling airlines to build competitive moats that support sustainable business models. Airlines with less fortunate geography will now be able to improve their economic geography by operating routes not previously possible. Not all airlines value fuel efficiency the same. The trade off between increased ownership cost and fuel savings is dependent on utilization.
To better understand which types of airlines value new-technology, we analyzed the forecasted share of single-aisle deliveries from 2016 to 2019. New-technology aircraft account for two-thirds of high-growth, high-utilization airlines' deliveries, demonstrating that the business case for these types closes at any fuel price if the operator flies enough. During this decade's technology transition, a variety of options will permit airlines to acquire the right tools to meet their needs. Lessors will play a key role, providing access to OEM's overbooked skylines and transitioning used aircraft between operators. While the price paid for the new-technology will be crucial to continued competitiveness, the timing of the adoption may be more so.
Filling the gap, it is concern a new idea in aviation industry, we can define an airline by three main factors, i.e Passengers demand, Market Fare, and Network distances, that is Stage Length, while Cost is consider as step function, the study shows there is a gap in locating the learning curve of the company to the typical operation one by using optimization techniques.

The BCG Matrix provides a visual representation that aids decision-makers in understanding the relative position of each business unit within the overall portfolio. It helps in resource allocation, strategic planning, and identifying areas that require attention or investment. Remember that the implementation may vary based on the specific dynamics and challenges each airline faces.
Forecasting is an important tool for planning, so without planning, there will be a disaster that may happen, i.e what will happen in case of Force Major
For study new destinations, Gravity Model frequently use, which is a tough approach that may not work sometime due to many economic factors in the world and war crises.

Memorandum Of Association Constitution of Company.pptseri bangash
www.seribangash.com
A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.
Amendment of MOA:
While the MOA lays down the company's fundamental principles, it is not entirely immutable. It can be amended, but only under specific circumstances and in compliance with legal procedures. Amendments typically require shareholder

Abstract:
Aircraft evaluation and selection is usually governed by the economical approach of aircraft
manufacturer companies such as, Boeing and Airbus, using cost per trip vs. cost per seat matrix. In
a point to point airline operating model, airlines are characterized by three factors i.e Demand of
Passengers, Current Market Fare, Distance between Cities - Stage Length. In this paper a new
approach is examined, by using the concept of U curve technique, and integer program. The cost
element is used as a step function in the program, defining the optimum operating curve of the
airline, which is representing by two main parameters: being the cost in terms of USD/ASK, and
the number of seats to be defined at optimum solution.
Hence airlines can position their existing fleet by mapping the actual cost of their aircrafts and
their applicable seat configuration on optimum operating curve to assign the right aircraft to the
right market segment. In case of airline startup, a fair evaluation and comparison can be derived by
mapping the typical cost of the aircraft and the typical seat configuration that is approved from the
manufactures on the operating curve of the planed network.
Keywords: U Curve, Operating Curve, Integer Program
1. Background:
Competition between Airbus and Boeing is a result of the two companies' domination of the large
jet airliner market since the 1990s, which is itself a consequence of numerous corporate failures and
mergers within the global aerospace industry over the years. Airbus began its life as a consortium,
whereas Boeing took over its former arch-rival, McDonnell Douglas, in 1997. Other manufacturers,
such as Lockheed, Convair in the US and Dornier and Fokker in Europe, have pulled out of the civil
aviation market after disappointing sales figures and economical problems, while the collapse of the
Eastern Block and their trade organization Comecon around 1990 has put the former Soviet aircraft
industry in a disadvantaged position, even though Antonov, Ilyushin, Sukhoi, Tupolev and
Yakovlev still manufacture planes. All this has left Boeing and Airbus in a near-duopoly in the
global market for large commercial jets comprising narrow-body aircraft, wide-body aircraft and
jumbo jets, even though Embraer has gained market shares with their narrow-body aircraft with the
Embraer E-jets series.
In the decade between 1999 and 2008 Airbus received 6,378 orders, while Boeing received 6,140,
always fighting for the best commercial figures every year. The competition between the two
companies is intense.
2
3. 1.1 Head to Head – Airbus vs Boeing
Actually on the surface, the battle between the two aircraft manufacturers appears to be the A380
versus the 787 – or size versus efficiency. Airbus,
however paints the battle as the A380 plus the
A330 plus the A321 versus the 787 and the rest of
Boeing product line, adding the dimension of
operating economics. As airlines continue to
recover and evaluate their future fleet needs they
will face a choice between the two competing
visions or strategies.
Fig. 1. Consolidation "hub-to-hub
The philosophy of Airbus is based on
Source: Airbus & Boeing Reports"
consolidation Fig( 1 ) i.e Hub to Hub operation
while Boeing philosophy based on fragments Fig(
2 ) i.e Point to Point operation, both strategies leads
to support their new products.
Thus, Boeing Company and Airbus Industries, the
competition between them is still very high, each
one has its own philosophy and approaches in
addressing the aviation markets, hence most of
airlines are relay to their judgment, and solutions,
of course some consultancy companies may offer
Fig. 2. Fragmentation "point -to-point
some traditional solutions which are not far from of Source: Airbus & Boeing Reports"
those solution, while airlines of third world
countries don’t have any solution except to accept
the traditional approaches of the major
manufacturers.
1.2 The Traditional Approach:
The traditional approach for selection and evaluation aircrafts is developed by the Relative Cost
Matrix (Cost per Trip and Cost per Seat Matrix), where a four regions indicate the four possibilities
that positioning the fleet concerning the study for the Aircraft of the origin (Study). That analysis is
always governed by the two major aircraft manufacturers in the world as Airbus Industries and
Boeing Group Companies which actually is a matter of products marketing; they use all the
marketing tools and efficient people to convince their customers. They develop their own cost
matrix, based on their successful stories, indeed the competitive is very fierce, which arise between
A230 Family and B737 NG.
Airbus Industries announced, that their aircrafts used the technology of Fly By Wire since they
manufactured A320, which their competitors lack to have this technology as shown in Fig ( 3 )
Airbus Cost Matrix, indicate the Gap of Technology with same range Boeing B737 NG, declaring
that their Aircrafts are the Best.
While Boeing Group plays on the reliability factors of the B737 classic types, which have a stable
and reliable Learning Curve for more than 40 years, based on that a B737NG is developed
declaring that their aircrafts are the best as shown in Fig ( 4 ). From above Statements and Relative
Cost Matrixes, the situation is contrary, airlines are not in position to argue the manufacturers
expertise of both Airbus and Boeing Companies. Also they are not willing to accept such situation.
3
4. 2. The Research Problem:
The problem comes out by the manufacturers themselves, the general and classical aircraft
evaluation method is Cost per Trip and Cost per Seat Matrix, for specified stage lengths ( 500 nm ),
each manufacturer developed its own matrix, which is unreasonable for the same input of the
airlines, as it is indicated by Fig( 3 ) and Fig( 4 ), the contradiction is obviously between them for
evaluation of the commercial aircraft for the same stage length (Distance Range) , for the same
aircraft types and that is not accepted by airlines. Hence either Boeing is Right and own the best
aircraft or Airbus is Right, both are not Right

3. The Methodology:
In the airline industry there are two network
operating models named:
3.1 Point To Point Operating Model
3.2 Multi Stops Operating Model ( Hub and
Spoke, Hub to Hub )
We will address the first model point to point
operating model – based on cost minimization
objective, the research basically is build on three
techniques and approaches as shown in the Fig (
5 ).
Fig. 5. The Model
3.1.1 U curve technique
3.1.2 Integer Program – Solver
3.1.3 Optimum Operating Curve

5. 3.1.1 - U Curve Technique
The concept of this technique is based on two
main costs: the first one is cost of offering
services, the second will be cost of losing
opportunity, the study will use the cost of
offering seats, while the second cost will be of
cost losing revenue due to unavailability of seats.
The minimum out come points of these costs
represents the best seat capacity to select. Similar
situation can be solved by this technique,
defining the best level preventive maintenance,
deciding the right number of engine in stock,
defining the right number of labor in a shift. The Fig. 6. U Curve Technique
final outcome curve takes the shape of the letter
U as shown in Fig ( 6 ).
3.1.2 - Integer Program – Solver:
Solver is the main tool used to solve U curve technique, based on the input of the airline,
(Passengers, Market Fare, and Distance between routes), it is the soft version of Linear Program
in Excel format. Solver can target three objectives:
1- Minimization Cost or the Errors
2- Maximization Profit or Revenue.
3- Designing the Required Budget.
This research is addressing the first objective (minimizing the cost) using the concept of U curve
techniques.
While Profit analysis is addressing the second objective using the model of Multi Stops
Operation.
3.1.3 - Optimum Operating Curve:
This curve is developed based on a number of
solved trails of U curve technique using the cost
as step function to get the right capacity at
various values of cost.
Finally a curve is developed and different types
of aircraft are positioned on the graph in terms
of typical seat configuration and typical
manufacture cost of ATK of the aircraft. It is a
very useful tool to hold a benchmarking study
as shown in Fig ( 7 ). Fig. 7. Optimum Operating Curve

3.2.1 Linear Programming
Linear Programming had its beginnings in the input-output method of analysis developed by
the economist W. W. leonteif. The present-day version is of more recent origin. Hitchcock first
interpreted a "transportation type problem" in 1941, while koopmans studied the same topic in
1974. In 1945, Stigler studied the "diet problem" (concentrated with separate entities that can
be selected and used in diversified quantities by choosing, combining, or mixing them with the
purpose of obtaining an expected result). The current state of the art is attributed to Dr. Gorege
D. Dantzig, a mathematician who introduced his "simplex method" as a systemic procedure for
solving a linear programming problem.
During 1947, George Dantzig (with Marshall Wood and their associates) was involved in a
project for the United States Air Force which resulted in the search for a technique capable of
solving military planning problems. The essence of the research lay in viewing interrelations
between activities of a large organization as a linear programming model and determining the
optimizing program by minimizing a linear objective function. Dantzig indicated that this new
approach could be widely applied to business problem, as is evident today.
Linear optimization models are characterized by linear mathematical expressions. In addition,
they are usually deterministic in nature; that is, they do not take account of risk and uncertainty.
The parameters of the model are assumed to be known with certainty.
So linear programming is a considerable field of optimization for several reasons. Many
practical problems in operations research can be expressed as linear programming problems.
Certain special cases of linear programming, such as network flow problems and
multicommodity flow problems are considered important enough to have generated much
research on specialized algorithms for their solution. A number of algorithms for other types of
optimization problems work by solving LP problems as sub-problems. Historically, ideas from
linear programming have inspired many of the central concepts of optimization theory, such as
duality, decomposition, and the importance of convexity and its generalizations. Likewise,
linear programming is heavily used in microeconomics and company management, such as
planning, production, transportation, technology and other issues. Although the modern
management issues are ever-changing, most companies would like to maximize profits or
minimize costs with limited resources.
3.2.2 MATHEMATICAL MODEL
If the Thumb is characterize by 32 characters, and the Eye characterize by 520 characters, what
are the characteristics of an airline,
There is a relationship between, Capacity, Frequency, Passengers, Fares, Distance, and Cost, so
any airline can be define by, Demand of Passengers, Market Fare, Distance between cities and
applicable cost. The relation can be illustrated by the following equation:

8. 4. The Program:
Spread Sheet is developed, including input data in
terms of passengers, market fare, and distance, the
program is developed based on equation ( 1 ), and
solver is setup, with constrained mentioned in the
mathematical model, the program will evaluate the
network based 100% load factor, i.e maximum
capacity of the aircraft, this will lead to good
comparison of the results to select the right capacity
as shown in Flowchart ( 1 ).
While in real cases, we can assign a new constrains
that reflects the actual load of the airline, and will
force the program to increase the number of
frequency and by trail and errors, it might be the
cost applied coincided with the existing aircraft seat
configuration. i.e once we know the right capacity,
we have to run the program again with a new
constrains to get the optimum frequency at that Flow chart 1.
level of capacity. But the best procedure is to create
a sequence of trail solutions by using the cost element as step function, to reflect the optimum
operating curve of the airline as in it is shown in Fig ( 7 ).

9. Using all the previous steps, the operating curve of Felix is developed as shown in Fig ( 8 ) The
input data can be taken on weekly, monthly, quarterly or annually basis. So Felix airways can
position its fleet according to the results of this curve but as they are in a lunching phase, the cost
element of its fleets is not available. The other world wide low cost carries are fitted fairly on the
operating curve as Air Asia, Air Arabia, Ryan Air and Jet Blue, it can also position any aircraft
having seat configuration less than 250 seats to reflect the typical cost per ASK.

5.3 Results:
The optimum operating curve of domestic network of Felix Airways, represents the best picture of
the typical seat configuration with respect to the required cost to achieved in Cost per ASK. It is
reflecting all the characteristics of the domestic market in terms of Passengers, Fares, and Distance.
6. Conclusions:
By this method only three factors can define an airline, which is actually fair enough to hold the
right decision to select the right capacity of aircraft without the interference and pressure of the
aircraft manufacturers, so each airline in the world has its own optimum operating curve, that never
coincided with another airline, and it is the only picture that is painted by the airline figures i.e
passengers, fares and distance.
In fact, it positions and defines the leaders in aviation industry, in a fair mathematical way that
derives the best economical results. Actually it is the hidden fingerprint to identify an airline.
