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

Image
  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

Toxic Cabin air may be causing neurological problems in airlines crew

Image
On 2nd Feb 2012, an aircraft took off from Stockholm/Bromma airport for a scheduled flight to Malmö/Sturup. After approximately five minutes the commander was affected by dizziness and nausea and therefore handed over the controls to the co-pilot. The flight was discontinued and the aircraft diverted back towards Bromma. Captain Andrew Myers, worked for JetBlue for 15 years but then in 2017 he became ill with a number of alarming health conditions, including toxic encephalopathy, which is a neurologic disorder, and neurocognitive disorder as well as visual difficulties, which could be permanent.The State of Oregon Workers’ Compensation Board in August 2020, ruled in favour of Myers, which in essence establishes the fact that Myers did indeed fall ill from toxic cabin air. This decision is significant because for years, the airline industry has denied the existence of what is known as aero-toxic syndrome, or exposure to toxic cabin air. Myers will now be paid several years of compensat

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

Spicejet bends all rules to fly to Gangtok airport risking lives, in the wake of Calicut accident

Image
Approach at Pakyong airport The cosy relationship between SpiceJet and the Indian aviation regulator stands exposed when each day passengers and crew fly to and from from Pakyong airport built on a table top with hills on one side and a deep valley on the other. Whereas passengers are oblivious to the risks involved with the flight that they are traveling on, the crew are living on a prayer that they come back safely. Gangtok is the capital of Sikkim which is the home to glaciers, alpine meadows and thousands of varieties of wildflowers. Steep paths lead to hilltop Buddhist monasteries such as Pemayangtse, which dates to the early 1700s. Access to Gangtok has always been by road which takes five hours to reach from the nearest airport, which is Baghdogra. Sikkim is also of strategic importance due to its location. The construction of an airport at Pakyong near Gangtok would therefore would hold much importance and with the inauguration of the airport by the Prime Minister in Sept 2018,

HANSA NG, India breaks the taboo entering trainer aircraft manufacture

Image
  India has rolled out the much awaited single engine basic trainer aircraft to meet with the requirements of training pilots who would graduate to become airline pilots.   Hansa - 3  is India’s first all-composite light aircraft designed and developed by CSIR-NAL a government organization in partnership with MESCO aerospace, ideally suited for ab-initio flying training, sport and hobby flying.  With this aim, the new generation HANSA is equipped with a glass cockpit, capable of Instruments only flying, electrically operated flap system and an imported ROTAX 912iSc engine which develops a continuous power of 98 bhp. The aircraft structure uses JIPREG composite, a National Aeronautics Limited technology. This   Computer Controlled Fabric Impregnation Machine (CCFIM) replaces the cumbersome manual resin impregnation processes, ridden with drawbacks like non-uniform wetting of fabrics, weave distortions and poor quality of impregnation, due to their dependence on human skills.
