Back in my younger days, a fellow EMB-120 crew had a oil low pressure indication on the left engine. Instead of following the memory items (which would have called for engine shutdown) they called up maintenance control (they were on approach to ATL) and described the problem. Maintenance said, "I'd advise you to follow your checklist!" About that time the engine seized.
Dispatchers/mechanics/management pilots aren't any better at thinking on the fly than flight crews. Follow the checklists immediately - most certainly this one in Chennai started with text about nearest airport, landing is first priority, etc.... Cool heads spend months writing checklists - deviate and you become a test pilot.
411A for once I agree with you - you DID take your pills today, didn't you?
