RASE an anonymous safety experience exchange system by Safety Matters

Image
 What is there was a simple platform to share our daily experiences, apprehensions, doubts etc with the world? Instead of small groups holding critical safety related information, there is a need for a pilot of a particular type or operating to an airport, to know whats bothering others around the globe with similar issue that they are facing with. Safety Matters/mindFly by Amit have created a simple to use application which is open for all to use. A few fields for data entry and a search options to retrieve data. It is anonymous and no personal or digital data is recorded. There is a approval process before the data is presented to the end users to filter out erroneous entries, malicious data and other anomalies. RASE is not a mandatory occurrence reporting platform and is just an experience sharing platform which is easy to use and can benefit others by sharing it freely.

FAA proposes draft B-737 Max Training only for US carriers & registered aircraft only

Image
B737 Max Flight Simulator  The FAA has released a f light standardisation board report relating to B-737 Max pilot training. Soon after, an addendum was issued too.  While FAA has clearly stated that the training required in the FSB is mandated for US air carriers & US registered aircrafts, other aviation authorities must take their own action for the return of the B-737 Max. Question, will the Indian regulator follow a systematic process of change management and not be rushed into the re-entry process? Will the FSB report adopted in toto and will the regulators draft training requirements be put out for public comments? The key highlights are quoted below from the FAA website as of 7th Oct 2020: While this is an important step, several key milestones remain: Final Design Documentation and Technical Advisory Board (TAB) Report  – The FAA will review Boeing’s final design documentation to evaluate compliance with all FAA regulations. The multi-agency TAB will also review the fi

Kozhikode runway friction delayed as top policy makers certify the runway safe for operations

Image
The runway friction test is mandated by the DGCA to be carried out periodically for safe flight operations.  A medium to big aircraft typically lands at a speed of 220-260 kmph. The primary means of stopping the aircraft is with the wheel brakes like any other vehicle. Since the runway length is limited,it is therefore important that the runway is not slippery & the wheels have a good grip on the runway by generating friction between the two surfaces.Lesser friction would mean lesser braking response. Factors that affect braking are the condition of the runway, dry/wet & rubber deposits. Each landing of the aircraft leaves behind about 700 gms of rubber from the tires due to sudden wheel spin up and this accumulates over a period of time depending on how busy the airport is.  If the rubber is not removed periodically, the grains of the runway surface which provide the grip get filled with the rubber and they become smooth. Adding to this if there is even a film of water few mil

Standards for passenger evacuation from aircraft not upated finds USA audit.

Image
  The current standard is to demonstrate that the aircraft can be evacuated by all passengers in 90 seconds using half the exits. There have been increasing number of evacuations where it has been observed that the pasengers were carrying their personal belogings or delaying the evacuation to collect their belongings. The test scenario is conducted with motivated volunteers who have been briefed on the scenario. However a real evacuation with changing passenger profile will present different challenges. FAA largely updates its evacuation standards only after accidents, and its last update that was based on an accident occurred in 1991 . FAA also has not conducted sufficient research on passenger behaviors and seat dimensions to determine how they affect evacuation standards. Furthermore, FAA does not collect comprehensive data from evacuations or data from aircraft model certifications to identify emerging risks and needs for regulation updates.

Boeing's reluctance to admit mistake & Indian Aviation master's perpetual state of denial makes two to tango, will the B-737Maxreturn?

Image
  Well begun but safety agenda got pushed behind William Boeing established his company, he went to his airplane factory housed at the Duwamish shipyard in Seattle and began to step all over improperly sawed “spruce ribs” until they broke. He used these wooden boards to build his new airplanes. The point, as relayed from his official Boeing biography, was that he was a perfectionist and demanded that his products be of the highest quality and safe. Unfortunately the philosophy was dissolved by those who took over the reigns of the company and instead of safety, production and profits became the driving force. Boeing has had a history of known design defects beginning with the B-737 Rudder problems, B-747 Centre Tank Wiring issues, B-787 Battery problem and finally the B-737Max MCAS. Attitude issue Indian aviation has faced their share of ups and downs. Unfortunately the masters who run the show do not defer or consult experts in the respective fields before taking decisions but rely on

Indian aviation's startling disclosure, upto 80% incidents due engineering/technical issues

Image
Facts as told by the Government! Indian aviation has witnessed an increase in number of incidents in the past few years and so has the traffic increased. The surprising revelation is that the 70-80% of the incidents are attributable to Engineering and Technical issues including component failure.15-20% Operational issues and 5-10% Human error. (Source Lok Sabha Question Answer 2020). The statement above shows that Human Factors is NOT understood by the policymakers and the people responsible for safety. The terms remains buried in text waiting to be understood. Globally, accident numbers have dropped significantly with the introduction of the Generation 4 aircraft types. Statistics over the life of each generation of jet show a significant improvement in the level of safety since the introduction of third generation aircraft and the latest fourth generation. Introducing TAWS technology with the third generation aircraft saw a huge reduction in the number of CFIT fatal accidents when co

Etihad incident at Calicut,June'19, highlighted airport infrastructure issues. This could have been the wakeup call!

Image
Etihad June 2019 Two incidents that could have saved the Air India Express accident at Khozikode. Unfortunately, no one acted on the concerns raised by the GCAA investigators. Isn't it criminal negligence? Synopsis First SpiceJet Q400 runway excursion in rain, August 2017 and now on 20 June 201 9 , an Etihad Airways, Airbus A320 - 232, registration A6 - EI T , operated a scheduled passenger flight EY2 5 0, from Abu Dhabi International Airport , the United Arab Emirates, to Calicut International Airport , India .  During the ILS approach to runway 28 , the flight crew initiated a go - around due to heavy rain over the runway as reported by air traffic control ( ATC ) . Approximately 16 minutes later, the flight crew initiated a second i nstrument landin g system ( ILS ) approach to runway 28.  On landing, the Aircraft touched down to the right of the runway centerline, and the right main landing gear then struck five runway edge lights. The Commander was able to steer the Aircraft

In Public's Interest, Govt. must release Air India Express accident preliminary report

Image
           The public has an overarching interest in safety data or safety information(ICAO) . The Air India Express aircraft VT-AXH accident at Kozhikode was unfortunate and a matter of public concern. The regulator made a public statement that in a few weeks, information on the circumstances leading to the accident would be released. It is over 30 days and the public is still being kept in the dark.  The reason this routine information is being withheld by the investigating authorities is quite intriguing since transparency promotes safety culture and awareness of the threats. Is it their lack of understanding of the investigation concepts or the usual posturing on the high horse? The regulation does not mandate the release of the preliminary report but at the same time does not restrict or recommend withholding the report from public disclosure . Objective of Investigation      The sole objective of an International Civil Aviation Organisation (ICAO) Annex 13 investigati

Calicut crash evidence tampered, damaged. Need for a judicial probe

Image
    The Aircraft Accident Investigation Bureau has failed in its primary duty that of securing the accident site. Not only has the site been contaminated but key evidence has been destroyed and stolen. Video recorded by media channels clearly shows how the aircraft cockpit was rummaged and desecrated by groups of people looking for something in specific. It just might be a key evidence in the accident investigation. A judicial probe must be initiated to carry out a fair and unbiased investigation. The letter written to the Secretary Civil Aviation reads as follows.   First Video: The video link shows the destruction of evidence    Second video:     The Secretary, Ministry of Civil Aviation, New Delhi, India Dear Sir, This is with reference to the Air India Express aircraft VT-AXH accident on 7th August 2020 at Kozhikode. This is also with reference to the emails sent to your office on 17th August 2020, 18th May 2020, 03 July 2020 & 13th August 2020 with the subject "Reinvesti

Fact Checked: ICAO mandates arresting systems on runways like Kozhikode, why was it not complied with?

Image
      ICAO has defined Runway End Safety Area (RESA) in Annex-14 as a standard that must be complied with. An area symmetrical about the extended runway centre line and adjacent to the end of the strip primarily intended to reduce the risk of damage to an aeroplane undershooting or overrunning the runway. 3.5.1 A runway end safety area shall be provided at each end of a runway strip where: — the code number is 3 or 4; and — the code number is 1 or 2 and the runway is an instrument one. 10.2 Where provision of a runway end safety area would be particularly prohibitive to implement, consideration would have to be given to reducing some of the declared distances of the runway for the provision of a runway end safety area and installation of an arresting system.   10.3 Research programmes, as well as evaluation of actual aircraft overruns into arresting systems, have demonstrated that the performance of some arresting systems can be predictable and effective in arresting aircraft overruns
