Question 3: Advantages and disadvantages of hydraulic system of aircraftHydraulic systems are used for operation of different components of small and largeaircrafts, including: flight control surfaces, brakes, constant-speed propellers, landing gear, thrustreversers, spoilers and wing flaps. Some of the advantages and disadvantages of these systemsare discussed below.AdvantagesUses incompressible fluid: hydraulic systems use incompressible fluids that results togreater, more efficient and consistent power output or force. This also results to minimal energyloss as all energy is transferred to the required area of the aircraft.Force multiplication: hydraulic systems use a small amount of hydraulic fluid to multiplysmall forces into large or unlimited forces and transmit them efficiently to remote areas of theaircraft where they are required. The pilot only requires to apply a small force that is thenmultiplied into a large force to perform the required function.Simple design and easy to install: hydraulic systems have a simple design comprising offew components that are very easy to install and maintain.Efficiency: precise aircraft control is very important especially during critical flightconditions. Hydraulic systems are able to respond efficiently and very quickly to controlinputs[ CITATION Mac17 \l 1033 ]. Pilotsrely on these systems to perform different flight controlfunctions without any worry on whether they will respond or the time they will take.
Reliability and dependability: hydraulic systems operate on very simple mechanicalprinciples. They have very few moving parts that significantly reduce failure risks. Thisincreases the efficiency, reliability and dependability of hydraulic systems.Less space and easy to maintain: hydraulic systems comprise of few moving components.This reduces space requirements of these systems and also makes their maintenance to be easy.Less components also makes hydraulic systems to be cost-effective to install and maintain.Lightweight: hydraulic systems are also lighter than most of the other mechanicalsystems of an aircraft.Shock hazard free: hydraulic systems do not require electricity in order to function. As aresult of this, hydraulic systems are not vulnerable to shock hazards and there likelihood of firehazards are very low[ CITATION Sim12 \l 1033 ]. This makes them safer than most of othermechanical systems.DisadvantagesThe fluid used in hydraulic systems is highly pressurized thus it poses risks such as burnsand bruises if the fluid leaks and gets in contact with human body.Hydraulic systems are susceptible to leaks thus require frequent checks and maintenance.Hydraulic pipes can burst resulting to series injuries to humansIf a leakage occurs in hydraulic systems particularly in hot conditions, the hydraulic fluidcan catch fire.Question 4: Maintenance requirements of hydraulic system of aircraft
