Qatar Airways avoids potential traffic collision with a crossing aircraft over Iran

Image
  A Qatar Airways newly acquired Airbus A-350-1000 series aircraft had a close call over Iran on 12th April when it came into close proximity with another crossing aircraft. The airliner equipped with the state of art technology and traffic collision avoidance system was seen climbing by about 500ft while cruising at 34000ft on a flight from Doha, Qatar to Los Angles, USA.           Flightradar24 plotted aircraft track The automated TCAS detects an incoming aircraft and if it identifies the other aircraft on a potential collision trajectory, she arms the traffic collision avoidance system. When the intruder crosses a pre-set threshold , the system automatically initiates an avoidance maneuver to provide the minimum safe separation between two aircrafts. Altitude increase/ Speed decay due to traffic avoidance In this incident the Qatar Airways A350 registration 97-ANO dropped its speed by almost 35km/hr while cruising at 888km/hr. This drop in speed at an high altitude is not safe since
