14. LINEAR LOAD
 Qf at tank number  5811.2
 Qf at tank two  1280.7

16.  Two independent hydraulic system
 Operating pressure is 3000 psi
 Hydraulic fluid used is skydrol 500B-4
 Each Hydraulic system consists of
Reservoir, manifold, shut-off valve, accumulator, priority
valve, one engine and electric motor driven pump

18.  Always release the system pressure before removing a
component from the A/C
 Never does any maintenance work on airplane with any
other specified oil other than the recommended one.
 Carry out the patch test on the system to prevent the
contamination of oil. This can be carried out using Millipore
patch test kit.
 Never mix different grade of hydraulic oil to service the
A/C.

22.  Expense for one airplane  11.067 million $
 Total manufacturing  13.10593 million $
expense
 Wholesale Price  15.674700 million $
 Wholesale price + VAT  18.809640 million $

23.  Seating type  3 Abreast
 Number of rows  16 + 1
 Comfort level  High Level Comfort
 Seat width  0.45 m
 Seat pitch  0.8277m
 Cabin diameter  2.27 m
 Maximum floor height  1.85 m
 Floor width  0.44 m

24. Total length of the passenger cabin = 18.14m
Total length of the cockpit = 1.90m

26.  Thus the designed aircraft is processed starting from the
initial geometrical parameters following its aerodynamic
characteristics, the loads acting on unit structure, integrated
designing , manufacturing techniques, the hydraulic
system, and even its economical valuation s are done each
step by step according to the valuable lectures given by my
professors and with the help of their textbooks. At last the
designed aircrafts seating layout is considered and cabin
length are found and sketched.
