Collision Aviodance

            Collision Avoidance: ADS-B or TCAS March 7, 2000 INTRODUCTION Background Collision avoidance is something that has been a problem in aviation for a long time. Most of the flights conducted today rely on the see and avoid concept and ground radar. Both of which have their flaws. The FAA predicts that mid-air collisions will increase by 300% over the next 20 years due to the increase in flights being flown by all areas of the aviation community (Kraus xiv). Civil aircraft have had onboard protection from midair collisions only since 1990 and general aviation aircraft are not required to have any collision avoidance technology onboard(www.cassd.org 1). In order to effectively manage the national airspace system in the future we will need to implement Free Flight. Free Flight is a concept designed to enhance safety and efficiency of the airspace by allowing aircraft to choose their own route instead of using victor airways (www.ads-b.com 1). Along with this freedom there is still the problem of aircraft separation which when on an instrument flight plan is air traffic control's (ATC) responsibility. In free flight there may be areas where ATC cannot give the required collision avoidance necessary. In order to safely manage the safety zone around an aircraft, pilots will need to rely on systems installed in the aircraft for better separation. Purpose The purpose of this report is to identify whether Automatic Dependence Surveillance Broadcast (ADS-B) or Traffic Alert and Collision Avoidance System (TCAS II) should be placed in all aircraft if the FAA decides that there is a need for some collision avoidance technology to be required for all aircraft. TCAS is currently required on all commercial passenger aircraft over 30 seats and ADS-B is currently being tested.

3. Rate of Reactions

Reactions take place through collisions between reactant molecules. However, under ordinary conditions, only a small fraction of collisions result in reaction. The rate of collision molecules can be calculated from the kinetic theory of gases. If every collision led to reaction, the reaction would be over in a fraction of a second. ... If, for a particular reaction, Ea were zero, all collisions would be effective. ...

4. rate of reaction

Every collision that occurs isn't always successful, one in every thousand million result in a reaction. ... The collision theory is the number of collisions per second, they are lots of ways you can change this. ... If they are more molecules present there is a higher chance of particles colliding, because more collisions occur then more successful collisions occur and then they react and increase the reaction rate. ... I will keep the temperature of the reaction mixture the same because if you increase the temperature you increase the number of collisions per second and the effective co...

Utilisation and the average number of collisions were effected the greatest. Utilisation increased from 21.8 to 40.6, and the average number of collisions increased from 8.57 to 51. ... The biggest change for these two simulations results was for the number of collisions in the network, for the third simulation where the interarrival time was 0.01333, the average number of collisions were 2.92, yet for the fourth simulation I set the interarrival time at 0.02667 and the results showed that the average number of collisions in the network were now 17.86, this is an increase of approximately 600%...

The Collision Theory The collision theory states that the particles of acid in a solution are in continual rapid motion. ...
