Session 4 at SOAR by Avembsys

        The session started off with the discussion of the assignment given to us.The assignment was an interesting venture but this was only the beginning, the actual implementation is yet to be done.The evolution of aircraft was introduced to us.Right from the drawing of Leonardo da Vinci, The Orinthopter, to George Cayley's model to Glider and the first successful airplane by the famous Wright Brothers.
        The classification of Aircrafts was done based on various features.they are classified

1. based on space they operate - Aircraft and Spacecraft
2. based on propulsion  - Propelled (Airplanes) and Unpropelled (Airships/Gliders)
3. based on crew - Manned (Airplanes) and Unmanned (UAV/RPV)
4. based on wings - Rotary wing and Fixed wing
5. based on type of wings - Monoplane, Biplane and Triplane
6. based on landing mode - Sea, Land and Amphibian
7. based on engines - Propeller, Turbofan and Turboprop
8. based on number of engines - Single, Twin and Multiple
9. based on function - Fighter, Bomber and Transport

Bermuda Triangle's weather disturbances

Each of the above classification was presented with visual treats helping us to make a better understanding of each.Various special type of aircrafts were also shown to us such as Reconnaissance,Airborne warning and control system (AWACS), Microplane, Aerial Refuelling, Vertical Takeoff, Stealh and Aircraft Carriers.

        For a break in all these facts, we discussed about lighter topics like the UFO's,science fiction becoming reality and the Bermuda Triangle.The high turbulence in this area and the unusual magnetic anomalies have caused 50 ships and 20 airplanes disappear.

         Then we were presented with a case study of Crash of Avianica 052.This video clearly showed the importance of communication between the ATC and the ill fated plane.The failure of the pilot to impose an emergency even though he asked for a priority landing and the failure of the ATC to pass on the information when transferred from on ATC to other, caused the plane to drain out of fuel thereby leading to a crash.

        We then discussed on the working of ILS system. In order to land the Aircraft, it must be perfectly aligned to the center of runway.How can this be done? Here comes the ILS antenna! A neat technology which sends two signals of different frequencies where the join of these signals correspond to the center of the run way. This is used for both the lateral and vertical guidance. The lateral guidance aligns the aircraft with the center of runway and vertical guidance aligns the aircraft with the glide slope.
