Investigators might want to consider the flight knowledge recorder, cockpit voice recorder, and different gadgets, together with professional analysis, to find out what occurred,” he mentioned.
The 2010 report had cautioned of operations at such ‘important airfields’.
The DGCA has categorized sure airfields as important which want particular qualification for the flight crew to undertake operations. The factors for classifying airfields as important are primarily based on varied elements resembling terrain, size of runway, predominance of inclement climate and many others.
“There are 11 such airfields, which embrace the table-top runways of Mangalore, Kozhikode and Lengpui.
