Like has been said before, the entire system in India is broken. Idiots with violent tendencies (fighting with their colleagues) and clowns with no ability to fly (landing gear extended for 2 hours) make it to the top because of money and connections. Inevitably, this results in a system and environment where good people and their good decisions and judgement take a back seat.
So sad but true....

However in this incident the weather at destination packed up direct routing to diversion wasn't possible due to weather around and alternate vis also dropped below minimum. The only decision could have been land, maybe Auto land bursting minimum or divert to another place reaching below minimum fuel. If there's an error it's in decision making not due to lack of skill. So it's OK not to ground them till the finding comes out.

When called back by ATC they were 37nm from Lucknow....and they landed with 200kg of fuel.
They were 58nm from Allahabad so extrapolating would have landed with....well fair to say would never have gotten to make the approach.

Immediately on making the G/A they went from MIN FUEL - which means nothing, just advice with NO NEED for ATC to assist/improve track miles - to MAYDAY FUEL so WILL be landing with less than 30 min of fuel total remaining.

The decision is made to divert using that 30 min total remaining fuel just to try and get to the "new" alternate let alone having to burn more fuel when configuring for an approach.
They would have been lucky to get near the airport before flaming out, unimaginable they would have any remaining fuel once configured.

In making their decision they decide to track away from an airport equipped with an ILS to another airport with uncertain weather (as shown already metars can change rapidly in India).

Suspects this will be an incident for discussion in CRM/Command Initiative courses for a long time to come.

The decision making process reminds me of a Swiss LX850 Report: Crossair SB20 at Werneuchen on Jul 10th 2002, landed before runway and impacted earth wall
At a certain point you better make a bold decision instead of running out of options. In both cases the crews luck did not run out but it was close. A Gimli glider in poor weather conditions has a very predictable outcome.

Quite the headline and then comes some clarity from Avherald as usual: Incident: Vistara A20N at Lucknow on Jul 15th 2019, landed with just 260kg of fuel remaining

Note the avherald report is the DGCA letter with a COMPANY note added.
The COMPANY states the drop in visibility made a "safe landing impossible".

NO!
It made a landing at or above the stated minimas unlikely (actual vis at minima Vs stated minima 5 minutes earlier) but no reason why a SAFE landing wouldn't have been achieved from a stable ILS approach.

The decision to leave Lucknow having already declared MAYDAY FUEL a separate issue for consideration.

Sometimes the system plays a huge role, two 737's in trouble.
At 1002, Velocity 1384 transmitted that they were on a 4 NM (7 km) final for the RNAV GNSS approach. At 1004, as they were not visual with the runway, the crew initiated a missed approach from 132 ft AGL. The FO reported that as they commenced the missed approach, it was possible to confirm that they were aligned with the runway by looking directly down. At 1012, ATC initiated a distress phase.The aircraft was positioned for a second approach, during which the cabin crew were briefed and prepared for an emergency landing, briefing the passengers to brace accordingly. A t 1014, Velocity 1384 landed at Mildura in foggy conditions with fuel below the required reserves.

An official regulator cannot state that busting the minima is equivalent to a safe landing.

Yes I get that.
Equally surely they cannot support the proposition that fuel exhaustion will lead to a safe/safer outcome??

As an earlier post said in regulatory talk/think they'd be happier for the aircraft to run out of fuel and crash rather than end up safely on a runway having broken minima's.
MIN FUEL call made - check. MAYDAY FUEL call made - check. Aircraft runs out of fuel, crashes and people die - well what more could the Flight Crew have done??

To finish it off - sure MAYDAY FUEL would count as one of those "Land ASAP" situations.
So: an airport you are presently holding over Vs an airport you MAY not have the fuel to get to; perhaps the regulator in their wisdom would like to publicly nominate which THEY think would be more suitable and why??
Wonder if the passengers on board would agree!

As I have written on an earlier post, I personally believe there are further considerations that should be made from the regulator's point of view with respect to alternate fuel planning, as there are flaws within the system. Diverting right at the minimum diversion fuel and not being able to land immediately at the alternate results in ending up in mayday fuel, unless the crew gave themselves some extra margin by increasing the required fuel figures "just in case". There needs to be some regulatory contigency on the alternate fuel as well, as a safety net if the crew judgement does not take all the variables into account, like it could be the case in this event.

I don’t know how persisting the bad weather can be in India but cancelling alternate and commit to land at destination might have been the safest choice in that case. Diverting with zero extra? Dangerous game IMHO.

Agree. It's somewhat fascinating what happened after an aborted approach due to tailwind at an airport with multiple runways.
Why no second try?
Change of runway?
But, I wasn't there and are not familiar with DEL anymore.
So just asking.

SONICBOOM et al
You're in a position where you can either;
- hang around and shoot another approach and decide what YOU will do to get in or
- divert to somewhere else and hope you can get there on fumes
and you want to talk about how the regulator "..might have done better...".

People are going to live or die - and you want to talk about regulatory theoreticals!
Really??

If, and I say if there are flaws in the system they need to be tackled so that the same mistakes are not repeated. In aviation there must be a fail proof system as consistent as possible and safety nets need to be placed where there is an identified risk. The regulations allow me to start a flight with minimum flight plan fuel and 0 extra fuel even with crap weather because a) I have contingency b) I have 1 or more alternate depending on circumstances. The regulations allow me to start a diversion right a minimum diversion fuel and land at my alternate with 30 min fuel (EU OPS) by following exactly my flight plan route. Are we doing this on a day to day scenario ? Of course not, because we assess the threats of bad weather, load extra fuel and use it wisely. Is this system fail proof ? Not at all, especially because we aim everyday on reducing the amount of fuel we carry by reducing contingencies, planning shortest routes flying through all sorts of weather, etc..
But I guess that if for every 100.000 flights one screws up and land on vapours then it's good enough for the statistics.

Sonic, I fully agree with your comment/opinion. With current regulations one can end up fully legal in a low fuel situation. During my command course (EU flag carrier) it was demonstrated how a flight in the middle of Europe (xxxx to LFPG for example) with min fuel may end..... But, it's not only the regulator, it's also a matter of company culture/training.

No it‘s not. With approaching 40 Million flights per year this number would mean one Gimli glider per day.

In an emergency, the commander may take action he considers necessary to ensure the safety of the flight including breaking minimums, however he must be able to justify his actions and will get a grilling from the experts who have had days to analyse a decision he had to take in minutes whilst under considerable pressure.

Breaking minimums or continuing to land from an unstabilized approach may be the safest option in some situations, but expect to have to explain how you got into that predicament in the first place, ie why didn't you divert earlier whilst you still had the fuel ? Some pilots would go around with minimum fuel and weather closing in simply because they were slightly outside the stabilized criteria at 1000' with a 4000m runway in front of them.

EDLB, fair call on the rate though I suspect it was never meant to withstand the scrutiny of real mathematics - just a figure of speech. Kindly note that data on how many arrive to land with less than FRSV are not available for review, thus we do not really know how bad it is. I assume the G.g reference was also not to be taken literally.

As FlightDetent said, mine was just a random number out there, just to emphasize that often what we call “safe” is “statistically safe”. It would be interesting though to run an experiment on a set of flights diverting right at minimum div. fuel in different kind of weather and operational constraints and pull out the statistics on landing fuel at the alternate.

I like to think not many divert at ALTN + FRSV level - after a go-around. If so, then without shooting the approach first thus carrying approx 12 mins more.

For the European operators, the more conservative decision to commit takes precedence, if WX, not a factor.
