(non-pilot speaking) Based on nothing more than living in the world for 50 years ...
- ICAO will take months to respond because everyone wants to do business with India.
- When ICAO do respond it will be half hearted and everyone will enter negotiations - this is up to a year away.
- Eventually (hopefully before real physical damage is done to pilots) India will settle for a new FTL plan that allows higher times and extended limits to everyone else. This means that they will have achieved their objectives.
