Session 5 @ SOAR in Avembsys

               This session was all about AVIONICS  SYSTEM-AVIONICS ELECTRONICS , many advisory agencies,at the end of session we discussed about one of the avionic system-EGPWS : Enhanced Ground Proximity Warning System and  also discussed in details about TCAS.
          AVIONICS  SYSTEM-AVIONICS ELECTRONICS                                                                                               
                  

Avionics is a portmanteau which literally means aviation electronics

               AVIONICS :definition -The cockpit of an aircraft is a major location for avionic equipment, including control,monitoring, communication, navigation, weather, and anti-collision systems. It is subsystem which includes all the software and hardware parts installed in an aircraft.

Avionics have few principle which are listed below :
  1.Safety
  2.Mission of Aircraft
  3.Life cycle cost
  4.Certification

                           After this we saw , different avionics system present in all aircrafts:-

• Navigation:              

                       Absolute navigation system

         Dead reckoning navigation system      

         Maping navigation system

• Flight Control
• Engine Control
• Flight Management
• Subsystem Monitoring and Control
• Collision Avoidance
• Weather Detection

              We also discussed about ELT - Emergency Location  Transmitter and it has the emergency frequecies like 121.5,203,246.

Avionics system in Miltary Aircraft:

• Radar Infrared and other Target Sensors
• Weapon Management

    Advisory Agencies:
   

AGENCIES

         

        
    

    FAA      Federal Aviation Administration

    FCC      Federal Communications Commission

    RTCA     Requirements and Technical Concepts in Aviation 

    ARINC    Aeronautical Radio Incorporated

    SAE      Society of Automotive Engineers

    IEEE     Institute of Electrical and Electronics Engineers

    JAA      European Joint Aviation Authorities

    EUROCAE  European Organization of Civil Aviation Equipment 

     

The last topic of the session was EGPWS-   Enhanced Ground Proximity Warning System:
seven modes of EGPWS-

1. Excessive descent rate
2. Excessive closure to terrain
3. Altitude loss after takeoff
4. Unsafe terrain clearance
5. Excessive Deviation Below Glide slope
6. Advisory Callouts
7. Windshear Alertin

  Finally the session ended with the discussion on TCAS:Traffic Collision Avoidance System

TCAS traffic display · Vertical deviation indicator     

TCAS is an aircraft collision avoidance system designed to reduce the incidence of mid-air collisions between aircraft. It monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder, independent of air traffic control, and warns pilots of the presence of other transponder-equipped aircraft which may present a threat of mid-air collision (MAC). It is a type of airborne collision avoidance system mandated by the International Civil Aviation Organization to be fitted to all aircraft with a maximum take-off mass (MTOM) of over 5700 kg (12,586 lbs) or authorized to carry more than 19 passengers.
