UNIT – IIAIRCRAFT SYSTEMS

Force that is applied at one point is transmitted to another point using an incompressible fluid

Fig: Hydraulic system used in brakes

Hydraulic system:

It is the system of wheels that opens before an airplane lands and closes after take off

The system also supports the aircraft while on the ground, taxiing or landing

Fig: Landing gear used before take off and after landing

Landing Gear systems:

Fuel systems for Piston and jet enginesComponents of multi enginesLubricating systems for piston and jet enginesStarting and Ignition systemsTypical examples for piston and jet engines

UNIT – IIIENGINE SYSTEMS

An aircraft's fuel system has a more profound effect on aircraft performance than any other airframe system.

Without fuel the mission comes to an abrupt stop

Fig: Fuel distributed around center of gravity

Fuel systems

Types of fuel:Civilian Jet A, Jet A-1, Jet B

Military JP-4, JP-5, JP-8

Basic Air cycle systemsVapour Cycle systemsEvaporative vapour cycle systemsEvaporative air cycle systemsDeicing and anti icing systemsFire protection systems

UNIT – IVAUXILIARY SYSTEM

An air cycle machine is the system that provides fresh, temperature-controlled oxygen to an airplane cabin

Air cycle systems

Flight Instruments and Navigation InstrumentsGyroscope, accelerometersAir speed IndicatorsTAS, EASMach Meters, Altimeters, Principles and operation Study of Various types of engine instrumentsTachometers, Temperature gaugesPressure Gauges, Operation and Principles

UNIT – VAIRCRAFT INSTRUMENTS

The instruments in the cockpit of an aircraft that provide the pilot with information about the flight situation of that aircraft, such as

altitudespeed and direction.

Flight Instruments

It is used to identify the present position and to determine the speed, direction etc. to arrive at the port or point of destination.
