In Goa Tejas passed flight flutter test diving from an altitude of four kilometers to almost sea level at 900 feet (270 m). Tejas recorded a speed over 1350 km/h.

or indeed in an engineering/control system IT project?

my knowledge in this area is very limited (am architect, not mgmt guy), I have never heard of agile being used in non-IT, but I would imagine if it were to be used, then you would come up with a list of tasks/items to be completed for a sprint and then track it from there on and see how it burns down. Say for LCA, integration of MMR and A2G trials could form a sprint. Maulaners can correct me if I am wrong in my understanding.

in complex engineering systems you also have higher safety requirements and considerable safety redundancies - which agile methods are not great for dealing with
if you're building an on-line sales system - shouldn't use anything else
right tools for the right job

real-time systems largely deal with sensors, actuators and embedded systems. the architecture depends largely on how much LRU controls requirements needed, and how much federated it needs to be monitored and controlled. for example, we are moving away from a federated control in LCA to more distributed control, still federated in monitoring and master controls for AMCA. These can't be agile-d.

agile methods needs to user v&v, and short in terms of project completion of a phase. it is a b@stardized view of things to apply largely on any project. 90% of resume have masala dosas content in terms of having done agile. if stories don't transfer into verifiable requirements, and which in turn into products, it is not agile. agile is for IT illiterate maasan managers, who wants easier control to whip a$$es, and do cya.

some times, systems drive requirements, especially in RT new technology (ref: AMCA), IAF will come asking later on, that they need this and that.

so, virtual reality world is ideal for near-agilish RT developments. visit ge/boeing and lm to learn more.

I thought this happened a while ago. Or is this new? Date? Source?

I am not sure if someone has already posted this here earlier but anyways can someone confirm if this the cockpit of Tejas trainer?

^^No that's the Pilatus PC-21 cockpit. I think someone mentioned this on the earlier page.

so no news about phyrring?

nice to know the squadron number. 45 is a nice one.

Beware of those who commit for a certain date and month - they will never mention the year

member_22605 · Post by **member_22605** » 27 Jan 2012 16:45

Hi people,
The NP-1 is currently undergoing EGRs and is expected to fly by the end of Feb, the LSP-7 is in a similar state but may fly slightly earlier, so Feb will be the merry month for all the jingos. I would suggest(if i may) my fellow rakshaks to have a little patience as we guys are sweating it out 24/7 to make things possible and while we are at it, we do not want to take any chances, because we cannot afford to fail. Same is the case with ALH/LCH.
Cheers!

Take your time. These are not easy solutions.

@Raghuk

Not sure whether you are the correct person to ask this question but why is this hurry among DRDO/ADA/HAL folks to leak out dates via blogs/media only to be proved otherwise? In case of LCA this has happened so many times that such comments regarding the timelines of LSP6-7/NP-1 sounds ridiculous to me.

Cheers....

Hey, are you the neeraj of the orkut forum?
Regarding the leaks, i am not sure who does it and am not sure if the leak is from an insider and i feel equally disgusted sometimes by the ridiculous dates that i see on the reports in the news, but some of the news is sort of accurate till we encounter a problem and from then on, its like back to square one primarily because everyday and every problem is not just an issue but a big lesson and the lessons learnt have to be incorporated throughout the line and that takes time and again as i said "We cannot and should not Fail"

take your time and thanks to you and your fellow group for the hard work and dedication

and ignore impatient jingoes

PratikDas · Post by **PratikDas** » 27 Jan 2012 18:40

I agree. Thank you for the update, raghuk. I had the LCA on my mind this Republic Day. It is so much more than yet another defence acquisition.

Please keep us informed if possible.

member_20163 · Post by **member_20163** » 27 Jan 2012 19:15

Well - Raghu seems to have that flame of hope... Keep going mate, we all are tuned to you.

SaiK · Post by **SaiK** » 27 Jan 2012 20:48

Interesting.. EGR ( meaning recirculation).. the only well known issue I am aware is of the Harrier VTOL. I am sure this test will be in flying colors with regards to Tejas design.

My only concern is the T:W.. have they met it given the understanding that they have put on more weight for naval variant.

thanks for the update raghu.

^^^^ It could also probably mean "Engine Ground Run"

suryag · Post by **suryag** » 27 Jan 2012 22:43

Thanks Raghuk. Dont worry about Jingos' nags(they are as harmless as SHQ's nags), it is just that we are anxious about indigenous programs and celebrate the success of the program as our own. I really appreciate the work that you and your team are doing. Godspeed for the launch of the two birds.

Btw what has LCH been named ? Rudra was for armed ALH.

he did mean Engine Ground Run. NP-1 already went through 1 series of such EGRs. Don't know what SaiK meant..

SaiK · Post by **SaiK** » 28 Jan 2012 04:16

sorry. I took a different meaning. pl. ignore.

great show raghuk et al, focus on the job and get it to IAF specs.

we jingoes will always support you guys.

Anyone has any idea about Mayavi EW suite, the Indo-Israeli JV? Which was supposed to be incorporated in even F-35 that Israel is supposed to buy?
Or EL/M-2052 being LCA's radar?

will LSP-7 & NP-1 fly in February ?

Aditya_V · Post by **Aditya_V** » 29 Jan 2012 19:11

Guys, some of the information RaghuK has probably cannot be disclosed in an open forum and the team is trying their best, they probably want to get the LSP-7 and NP-1 up in the air more than us.

Let us not try this game get him to commit February and then if for some unexpected reason there is a delay lets not pummel him. He is a team member and not team incharge, sometimes problems over many days are solved when an unexpected solution comes.

Please read all the previous pages of this thread.

Ya but there is no confirmation that US choked us of Elta 2052 or even that we have Elta/MMR Hybrid. Or even LCA carries any radar.

Rahul M · Post by **Rahul M** » 29 Jan 2012 22:53

was there ever any concrete info about 2052 on LCA beyond rumours ? I don't think so.

welcome to BR btw.

What nonsense. Where have you been for the past 2 years? the LCA (LSP-3) first started flying with the MMR/Elta 2032 hybrid radar on April 23, 2010.

Nothing called the Mayavi suite. Its a myth. LCA prototype is being fitted with RWJ - radar warner jammer, a state of the art EW suite, variants of which are on the MiG-27 and MiG-29 upgrades as well
