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

Bubbles, the risk based solution by United Nations Aviation Body


The impact of the coronavirus disease (COVID-19) pandemic on global air transport is without precedent. Airports have seen a 28.4 per cent decline in global passenger traffic volumes for the first quarter of 2020, equivalent to a reduction of 612 million passengers in absolute terms. For airlines, the revenue passenger kilometres flown (RPKs) worldwide were down by 94% on the previous year. International RPKs were down 98%, as the passenger side of the industry was virtually grounded. With second waves of the virus impacting various countries and leading to renewed travel restrictions, international air travel remains minimal at -88% down on last year in August. These volumes (domestic and international traffic) are expected to decrease by 50.4 per cent for 2020 as a whole as compared to 2019 figures. ICAO estimates that, by the end of 2020, the COVID-19 impact on scheduled international passenger traffic could reach reductions of up to 71 per cent of seat capacity and up to 1.5 billion passengers globally. Airlines and airports face a potential loss of revenue of up to 314 billion USD and 100 billion USD, respectively, for 2020.

Risk-based stages for mitigation measures

Resumption of higher volumes of passenger air travel will be dependent on a number of factors, including foremost public health agency guidelines (driven by travel risk levels), governmental travel restrictions and requirements, passenger confidence, and air carrier and airport operational capacity.


A risk-based approach will enable the transition between stages of restarting operations and the adjustment of mitigation measures based on risk, while recognizing that reverting to previous stages may be necessary. The goal is to maximize consistency and develop criteria for data reporting and the monitoring processes in support of evaluation and progression to the next stage(s). It is currently not feasible to provide any specificity of timing between these stages. At the time this document was published, most of commercial passenger aviation was in Stage 0 or 1.

Stage 0:

A situation with travel restrictions and only minimal movement of passengers between major domestic and international airports.

Stage 1:

Initial increase of passenger travel. This initial stage will coincide with relatively low passenger volumes, allowing airlines and airports to introduce aviation public health practices appropriate to the volume. There will be significant challenges as each stakeholder community adapts to both increased demand and the new operational challenges associated with risk mitigation. Health measures for travel required at airports will need to, at a minimum match those from other local modes of transport and infrastructure.

Stage 2:

As health authorities review the applicability of measures based on recognized medical criteria, passenger volumes will continue to increase. Several measures that were required in Stages 0 and 1 may be lifted. Health measures for travel required at airports will need to match those from other local modes of transport and infrastructure.

Stage 3:

This stage may occur when the virus outbreak has been sufficiently contained in a critical mass of major destinations worldwide as determined by health authorities. The reduction of national health alert levels and associated loosening of travel restrictions will be key triggers. Risk mitigation measures will continue to be reduced, modified, or will be stopped in this stage. There may not be effective pharmaceutical interventions (e.g. therapies or vaccines) commonly available during Stage 3, but contact tracing and testing should be readily available. Until specific and effective pharmaceutical interventions are available, States may need to continue to loosen or reinstate public health and social measures throughout the pandemic.

Stage 4:

This stage begins when specific and effective pharmaceutical interventions are readily available in most countries. There may be a set of residual measures/mitigations that could be retained, although these should also undergo a periodic review process.


Note: There are no hard boundaries in these stages and the transition between them can be in either direction.
