Civil flights stuck in the 5G web, a difficult choice

      The recent USA regulatory circular on the affect of 5G network on flight operations has thrown the aircraft makers in a tizzy. The 5G network which has been rolled out in various parts of the world has subscribers drooling with the promise of blazing internet speeds which could download a movie in 5 seconds.  The 5G network affects the operations of the radio altimeter of the aircraft which could interfere with various systems like the automatic landing, Ground Proximity Warning Systems, Displays etc. The two big aircraft makers have approached the FAA to help mitigate the risk by delaying the launch of the 5G network in the USA. The question which arises is, what about the rest of the world where 5G has already been deployed and aircraft flying in and out daily? Well yes, the airline industry would loose billions as the flight operations would get impacted especially in poor visibility conditions. However, there doesn't seem to be any concern towards possible lives being los

Toxic Cabin air may be causing neurological problems in airlines crew

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

  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

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

  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.
