Not that simple it's a plethora of vendors, whose subvendors etc etc. If Tejas is tax exempt then any telephone supplier or Hotel room related this will have to made exempt as GST credit will not be available. Compiling with this will be headache for everyone involved This is probably the easiest s...

This is a great word, i wish i knew it existed a long time ago. I had done my MS in the US in '99 and can totally relate to and confirm what "Sum" is saying. Me and my fellow desi students knew and were worried about this exact thing when we were interviewing for jobs. The worst thing that...

Yeah! Mission planning is really thorough and I cannot even imagine how much planning went into our Pitch Black Ex participation. And did some searching around after the video and found that the speed tolerance for a drogue/probe refuelling contact is +/- 1Kt! :shock: I think I prefer the Boom type...

Was watching RIAT(Virtual) and got to know something that I hadn't known earlier: A ferry of fighter from the UK to US(6K Km distance) involves 8 Mid Air refuelling ops en route because the planning takes to account an emergency where the (multi engine) fighter has to be recovered at the nearest ai...

Are there any simulations done for duration of social distancing norms that need to be followed collectively so that we can get through with the epidemic? That would be more interesting as it would help in resource planning and management. Here is a very nice article on WaPo with simulations for nu...

What a gorgeous shot! IN P-8I Neptune. Twitter link What an awesome shot of the P8I, will have to make it my wallpaper :) Did anyone notice the cable streaming out of the vertical stabilizer top? is that a towed decoy or a ELF antenna to communicate with undersea subs? If you observe carefully, you...

1. Customs duties were imposed on the import of fully assembled phones, the market is huge and assembly in China is becoming more expensive. 2. There is no real base for high volume semi conductor manufacturing in India, it takes ages to setup a fab and other associated industries to make the high t...

Sachin, thanks for the detailed reply and additions to what i had written. We really need a lot more policemen who are better paid and respected by the general population as the work they do is hard, unforgiving and can leave them with lifelong PTSD. I hope that the government will pay heed to the s...

Idiotic police. Looks like father complained to police, but police responses were, "this is not our jurisdiction", "she may have eloped".. Police asked did she elope? Priyanka mother on police negligence - TV9 https://www.youtube.com/watch?v=qXkajPLA-e0 Actually this is a pretty...

vcshekar, Do you guys temper the solder in oil bath to relieve stresses in solder? Are you familiar with David Pinsky algorithm for tin whisker formation? 1.

ANy chance that AIM 120 C-7 acquired for Nasams with wink wink from Uncle be ported onto aircraft carrying EL 2032, EL2052's, French M 2000 and Rafale? well even israel was unable to get the amraams integrated into its Elta radar and uses stock APG68 radar on f16I-sufa. same case for f15. till date...

I have been thinking about the M2K pitch oscillations due to the flight computer commanding the pitch down violently. Reason is there is a possibility of tin whiskers (from the solder) growth in the circuit cards with time. Tin whiskers grow due to residual stress in the solder as it shrinks. Takes...

Thanks very much for the book recommendation, i will have to get it.

Last news was that the carrier was being refitted for its final journey before a decision was taken as to where she would end up as a floating museum,etc. I would advise the MOD/IN to keep her ins ervice for another year since the situ with Pak is dangerously close to an escalation of conflict.The ...

Would ACM Raha be the first serving IAF Officer to fly the Tejas or are there IAF pilots on deputation to ASTE? All Tejas test pilots are serving IAF (& IN) pilots on deputation to ASTE for 2-3yrs. AirCmde Rohit Verma was a Chief test pilot in 2011 quit service as IAF overlooked him for promoti...

How does the Bison compare with the F-16? During the first Indo-US exercises,the Bisons reportedly even saw off the F-15s! That exercise has been discussed to death many times over here. Gist was that the americans were overconfident and the IAF used its advantage to great effect and scored a lot o...

I read this report and thought that something was off in the reporting.

The numbers estimated for the Akash system are 30 per month presently and moving to ...

With regard to the LCA program - the Tejas' flyaway cost of $25 million is pretty accurate. What you're disputing I think is the R&D cost (~Rs 8,000 crore) which is a fair point. Though given the typically cheaper cost of labour its probably not off by that much. Also, we must recognize that a ...

All govts pay pvt companies to develop defence products Even in case of rafales French govt paid money upfront to. Dasault to develop and test flight the rafale This is true. But you have to remember that the advantage of the sunk R&D cost paid for by one government will not be passed on to a f...

I meant the money was already paid for from 2007-9 budget. when we sign a contract both tech spec and cost is set in stone. Today's real cost will more or less remain the same. 1bn for 20 equates to 50 mln a piece. I don't know what to think of it, but, even though the money was allocated, it would...

I don't understand the context of obsolescence here. I have my own view of obsolescence I hope I am not mixing up things. Now lets take the case of LCA. If I remember correctly, the first order of 20 LCAs amongst few other things were placed sometime around 2007-9 when pranabda chaired a CCS meetin...

Agree, but who knows it's few bulbs. It can be for all the aircrafts in service with the IAF, which itself is a huge number. And what about export of the same. :) Its very nice of you to say this, but, there probably are 1000's of types of bulbs across the fleet and each of them would have their ow...

Sorry to have missed the meet. Will make sure that next time i will make it to the meetup.

I dont know where you got this information Narayana but the F16 was always designed to be the ultimate lightweight dog-fighting aircraft. In fact, the F16 embarrassed the F15 in the initial stages and that caused a great deal of heartburn among the F15 proponents in the USAF. This was among the bigg...

No lynching - it is a fair opinion, and I happen to agree with it. [RANT ON]I can understand the IAF wanted something smallish as a MiG-21 replacement and so they went with the LCA "smallest/lightest" goal. But what constrains the Navy from going slightly bigger? I would hardly be surpris...

^^^ But we can spend it on training near the end of their shelf life. Albeit not the nuclear ones :). In fact they are used for live fire testing by all the squadrons.

Good point Shiv, I had not thought about it that way. So after some digging about this topic. It seems that the smallest thing that you can see is what subtends one minute of an arc (ie 1/60 or 0.016 degrees). when the object itself is not radiating any light. At 20K meters a 20 m long object will s...

I was also surprised about the distance numbers, but, the difference in eyesight is pretty remarkable between civilians and fighter pilots. For example, i was at a air show with my friend and he was able to visually pick up fighters (Mig21's and Jag's) way before anyone else in the group. Where we c...

"It is a huge machine, very easy to spot from over 10nm visually .. :eek: :shock: I hope this is a typo. I can't see a 747 at 5 NM (34,000 ft) let alone a fighter one-third its size. I would not be able to see a lo-viz MKI even at 2 NM. But If my life depended on it, I'd say the same thing tha...

vcsekhar, I agree with what you are saying. Some of what the Col said was vaild but I think you would agree that he was very selective in his description of Su-30. Also, his mistakes, which include his description of RWR and datalink among other things, have been well documented. Regarding WVR, wel...

vcsekhar, No doubt that MKI has the biggest RCS. But tell me how that matters? It seems that you have friends among IAF pilots. You may ask them the "effective" ranges at which BVR missiles are fired (especially R-77). He may or may not give you the exact figures, but he will tell you tha...

Rafale seems only game in town at the moment. pros - no US style "issues" , good family of weapons already integrated, works for A2G, works for A2A, well regarded "spectra" EW, can be used from IN carriers as well, ..... only con would be its smallish F-16 sized nose and resulta...

If I remember that briefing after Red Flag, the US officer was quite dismissive of the French. He said something like that the French were just there for snooping and not interested in too much aggressive action. So there is something between the US and the French, especially when it comes to Rafal...

This is pretty much what happens when all the development expenditure is amortized over a small number of aircraft. The entire production run of the rafale for the AdlA +Navy is less than 200. This is interesting when you compare the production run of the EF is over 600 and still the cost after amor...

There have been a lot of posts about the rafale swing role capability and I am having a hard time imagining why this is a difficult thing to implement in any aircraft. The Radar remains the same, the pylons depend upon the stores selected, the aircraft targeting software is not changed for each flig...

the crashed plane looks like a mig-23, if you look at the tail.. there is only one engine visible.
The su-24 has two engines.
