Slippery runway & more so the safety area at Kozhikode may be a leading cause of the Air India Express crash

RESA  The entire state machinery is on overdrive to defend the Calicut Airport stating that it was completely safe for flight operations. There are two significant points to focus on while determining the causes of the accident.  1. Previous safety audits have pointed to vegetation on the runway end safety area (RESA). 2. The rubber deposits at the ends of the runway may have been a contributory cause of the accident. Comparison A comparison of the runway friction values indicates a possibility of higher rubber deposits or poor runway friction levels at both ends of the runways. A friction level below 0.47 requires maintenance action as per the Indian Aeronautical Information Publication. The combination of runway friction and vegetation on the RESA may have been a significant factor that may have caused the Air India Express 1344 runway overrun at Kozhikode on 7th Aug 2020. Must note that the runway has a pronounced crown close to the middle and drops more than 25 feet on either side.

  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 bill
