1. The Vikramaditya and presumably the Vikrant are fitted with a host of very specific, closed-looping landing and navigation aids specific to the MiG-29K aircraft. This includes the LUNA optical landing system.
2. The Russian Resistor-E air-traffic control system is interfaced with the MiG-29K and provides landing and navigation to just 30 metres short of flight deck. Again, I assume this would be the basis of MiG ops on the Vikrant.
3. I don't think the elevator is a problem - there wouldn't be prospective trials if that were the case. Would be interesting to see what the load-out of a Rafale-M would be for operations on a ski-jump off Viraat.
4. Could she take off with an Exocet and a complement of 4 air to air missiles? Or for that matter operate with a minimum of 6 air to air missiles including Meteor plus Mica ?
Vikrant, not Viraat.

1. THREAD: Multiple reports, with fragments of detail on the CDS chopper crash, skirt the possibility of pilot error. This report says ''CFIT [Controlled Flight into Terrain] means the helicopter was airworthy and the pilot was not at fault.'' Really?
indianexpress.com/article/india/…
2. - How exactly do you fly into terrain in a controlled manner without there being gross pilot error? Why would any pilot get into this situation at all? Its crucial for the @IAF_MCC to be transparent about what happened.
3. Aviators will tell you there is hardly ever a single cause of a crash. Crashes happen for multiple reasons - Here's what I would like to know ...

1. Sources tell me it will take between 4 and 6 hours at Delhi airport from Dec 1 to get results of an RT-PCR test before one is allowed to exit or take a connecting flight. They will process 400-500 PCR tests per hour. Lets do the math on what this will mean for passengers.
2. An average Europe to Delhi direct flight takes 8.5 hours. Add 2 hours at the airport prior to the flight (minimum). 6 hours at Delhi airport. 1 more hour minimum to clear customs and immigration and pick up your luggage. That's 17 hours minimum as you leave Delhi airport.
3. Add a minimum of 2.5 hours for a connecting flight through the middle-east. 19.5 hours.

1. Unless our big international airports wake up to the new norms for international arrivals from the 14+ 'at risk' nations from December 1, there will be out and out chaos at our airports as thousands line up for RT-PCR tests and wait for the result before exiting.@JM_Scindia
2. Absolutely essential for our airports to massively ramp up RT-PCR testing facilities while working to deliver results for all passengers within a specified number of hours.
3. Imagine the plight of thousands of passengers, including children in holding areas waiting for hours while potentially exposing themselves to Covid in a closed space. Many arrivals from Europe would have spent close to 9 hours already on an aircraft.

1. Not quite. This 100 home village, construction of which qualitatively changes the status quo in the region, WAS constructed in `a short time.' On the left, an image from Aug 2019: No village. On the right, an image from Nov 2020: Village complete. 📸: @planet
2. By constructing a village on Indian territory that it claims (India considers this an illegal occupation), China categorically violates Article VII of the 2005 bilateral agreement between India and China. How? Read on.
3. The agreement says, ''In reaching a boundary settlement, the two sides shall safeguard due interests of their SETTLED populations in the border areas.'' (more)

1. Never be fooled by apologists for Chinese expansion in Arunachal who will deflect, obfuscate, allege motives and draw false equivalences to `manage perception.' This thread lists key quotes from experts with immense credibility, decades of experience.
2. Renowned Tibetologist Claude Arpi: ''The village is well South of the McMahon [Line] and the Indian perception of the Line of Actual Control.''
3. Renowned Tibetologist Claude Arpi: Construction of the village ''is an extraordinarily serious issue as it has many other implications elsewhere on the boundary.''
