- 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.

- 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.
