This report from Deccan Herald carries the title “M’lore flight ignored advice on navigation.” When you read the full report, it tells you this:
In February this year, the Director-General of Civil Aviation (DGCA) issued an ‘operations circular’ to all airlines, advising them to install GNSS equipment to ensure navigation accuracy.
However, Air India Express, which is a low cost airlines of Air India, doesn’t have that facility, nor perhaps, any other airline in the country.
So, it was not just the particular plane operated on the ill-fated flight that did not have the navigation equipment.
So, why this particular headline which implies that IX812 did not have the equipment but others may have it?
The sane thing to do at this point is to wait for the results from the examination of the black boxes which now have been found and not try to confuse people with misleading headlines.
