Air India Express accident at Calicut was facilitated by the regulator, how?

  Air India Airbus Landing at Port Blair (Source Dr Puneet) Blaming the pilots alone for an accident is like addressing the symptom rather than the root cause. The root cause of the Calicut accident of IX1344 on 7th Aug 2020 is the poor safety culture prevalent in India and the ineffective regulatory oversight. This landing(YouTube video) can be categorized as a deliberate attempt to endanger the lives of passengers and crew. This is not the Calicut landing but a landing at another critical airport where most of the year the airport experiences tailwinds. Since the airport has a unidirectional runway ( landing from one direction only), the flight crew has no option but to land in tailwinds. The situation worsens during the monsoons when there is a tailwind and the runway is wet and braking action reduces. Action has not been taken either by the regulator or by the airline safety. Why? What is the role of the regulator? The Directorate General of Civil Aviation (DGCA) is the regulatory

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

  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
