Sirs, I have no data but there was a sudden death in our locality. All symptoms and past history medical/travel is suggestive of what was the reason. Local doctor and the one who declared the demise is saying the same thing. Government contacted, not a word on it and certainly the number didn't bump...

I am no expert but a recent event nearby makes me think that: 1. The numbers being reported do not reflect reality. Not fudging the numbers but general callousness of government apparatus towards public in general is causing the low confirmed numbers. 2. Few prospective cases are being tested likely...

The traditional autoland in commercial airlines is ILS only and this capability is there since long, nothing new there. So I believe Dileep is referring to AI computer vision guiding the plane with ILS aiding it or the other way round. Again like a human pilot monitoring the ILS landing, ready to ta...

Artificial intelligence is like trying to guess/predict vs exact measurement (with sensors and a program). Traditionally, humans code software for all possible scenarios that one could encounter for a specified task like, say, auto landing/takeoff which is complex, testing intensive and error prone....

IMHO delhites are better off financially than rest of India comparatively. I have seen many in my circle appreciative of freebies even when they dont need it. Many are crorepati types. Greed and selfishness has no ends it seems.

Just guessing here. Maybe the pilots are using higher flex temp than needed or using TOGA during hot and high to have more buffer and this is what the report is alluding to. But in any case, it should not lead to failures if they are observing the operational limits.

What amazes me is why MCAS was designed to operate out of one aoa sensor. Max already has two sensors, all they needed was to use data from both. Secondly mcas had no min max values for stab movement. That is another blunder. Every time it triggered, it used aoa value to calculate stab movement irre...

IMO MCAS is all about money and not safely or stall avoidance. Mcas doesn't work with flaps extended so any use cases involving landing and takeoff are ruled out. Mcas was created to allow max to grandfather the certification from 737 NG. Boeing told regulators that max is an iteration over the earl...

IMO, the huge engines were moved forward and upward to accommodate them under wing. MLG was also modified to increase ground clearance without impacting the wheel well size. This caused a pitchup tendency during high AOA and thrust situations ONLY due to engine nacelle generating extra lift which wa...

the Tigor EV comes with a piddly 40hp engine and costs 12 odd lakh rupees. The torque curve of electric motors is pretty flat and quite independent of RPM unlike an ICE. EV's drivability is super smooth and almost linear unlike an ICE and is great in an urban environment. The 100 bhp ICE would be g...

With 300+ range it should be ok for commuting to work and local usage. Any idea as to price? That's what Tata claims. It has 30.2 KWHr battery. In actual conditions of a full load of 4-5 passengers, cargo , and with AC on, range will be reduced by half. Some 17 lakhs is quite expensive. Not exactly...

An imaginary box can be calculated around the target based on range and angular resolution of Phalcon at the max desired/practical range of BVR engagement.

It is my understanding that they are statically stable. There is no need or benefit to go otherwise. Remember that stabilizing under software control is energy inefficient. The constantly moving control surfaces cause extra drag etc. Even the MAX should be stable normally, but go tits up and stall ...

Guru log, what's your take on Tata motors for long term i.e. 5-10 years horizon? It has hit 52 week low twice and DVR is trading at 120 levels now. With their current/upcoming product lineup, I don't see any hindrance in Tata motors gaining the top spot.

Singhaji, high bypass turbofans efficiency stems from the way they generate thrust and their operating envelope. In commercial high bypass engines, 80% of thrust is generated by fan. They have more stages in LP turbines than military leaky turbojets (which nowdays have single stage for both LP and H...

I agree. Recently went with a friend for test driving Baleno and Tigor. While holding the hood and doors, He remarked that they are much flimsier in Baleno and felt heavy in Tigor. But honestly if the chassis is strong, thin panels (to save weight) should not be a problem. Even the newer nexon is ba...

If you ask me, the recurring issue with TATA is weight. There cars are heavy as compared to competition. For example Zest is 1135 Kgs, Dzire weighs 895 Kgs, Amaze 940 Kgs. This weight means low fuel economy though not by much. Zest Vs Dzire fuel economy differs by 1/2 Kmpl in city. But this weight a...

Neither EV nor ICE are meant for water fording. Regarding normal mansoon operations, we have erikshas merrily operating 24X7/365 days without any problems.

As pointed out by JayS, afterburner does not put that much stress on engine as the core combustion does on combustor, diffuser/turbine nozzle/stator and turbines.

Historically yes but like everything else Tata is changing as well and in a good way. Just look at the Nexon and it is hard to believe that it is a Tata.

Why did it turn left before going down? Maybe it was not part of the schedule to go outside of the runway? Trainee tried to correct it by turning left but the momentum carried it beyond that point and IGE to OGE caused it to loose lift rapidly and before the situation could be corrected it crashed.
