Maybe I was not clear....I was referring to "another delta" being another Lca in the air.

Ok sorry about the confusion, please post when these birds come for landing.

SagarAg · Post by **SagarAg** » 09 Mar 2012 16:34

Raghuk ji how long is the test flight duration ?

(Happy Birthday in advance)

Aditya_V · Post by **Aditya_V** » 09 Mar 2012 16:36

per Tarmak007, it is expected to be 25 mins. I think the bird flew `16:20 IST, expected landing should be ~ 16:45 IST.

^Does this LSP-7 flight have anything to do with my trip to BLR tommorrow? Guess they were scared of this jingo coming to town to shoot some butterflies

Maybe I should shoot butterflies more often, maybe even some dolphins

ps: happy birthday raghuk. Would said have a beer for me, but maybe shouldn't with all your health problems. Anyways good job and convey our regards to all your colleagues.

Its expected at around 1700. The intake has just been more aerodynamically reshaped and it still exists and has not been closed.

LSP-7 comes into to land!

It must have come in from the east. My line of sight is somewhat blocked for landing altitudes

Aditya_V · Post by **Aditya_V** » 09 Mar 2012 17:09

RaghuK has the bird landed ?

member_22605 · Post by **member_22605** » 09 Mar 2012 17:10

MKI lands and will probably be followed by the big Illyushin and yes the LSP-7 landed at around 1650

AK PHYREE ARR PEE GEE Pfyre.

Congrats to the folks at HAL/ ADA etc. I guess LSP-7 is the final config for Tejas MK 1

Many Jingos seems to have missed the Friday evening good news

Kailash · Post by **Kailash** » 09 Mar 2012 18:19

Jingo kush hua

Whatever is said on the forum during the repeated delays is only out of desperation and inability do anything (as a jingo). Again goes to show the commitment of the teams which works on the ground solving the problems, whose details we may know never know fully.

Toast to their dedication. Happy about the first safe flight of LSP-7

sombhat · Post by **sombhat** » 09 Mar 2012 18:33

Congrats Raghu, and happy B'day. Will LSP 8 be close on the heels, or is there going to be a wait for that too. Pls. disclose only if appropriate.

Has it been moved to the sides? I can see a scoop there...

nrshah · Post by **nrshah** » 09 Mar 2012 18:58

Great news...

Infact, i was hoping it happened on 6th March (My birthday

).

Last year, DRDO gifted me Interceptor missile test, so expectations were high this time...

Belated but nontheless, very very valuable and memorable gift... Thank you DRDO/ADA/HAL/IAF and all involved.

RKumar · Post by **RKumar** » 09 Mar 2012 19:22

Honestly, I was expecting NP-1 to fly first and then LSP's. But both are equally welcome and jingos will be happy as long as we keep adding air frames .... Keep it up guys and gals out there.

)

Happy b'day to you in advance

LiveFist.blogspot.com has first photos of LSP-7 in flight. There are three low res photos.

Looking at them, I had a question. The earlier LCAs were flown with dummy R-73s on the outer pylons. LSP-7 didn't carry any missiles on its first flight, only the outer pylons. I was under the impression that they were required for aerodynamic stability(LCA can fly clean, but during test phases, I was told it provides stability). Wonder why the change in this LSP.

Hitesh · Post by **Hitesh** » 09 Mar 2012 20:43

What's so special about the LSP-7 plane? I am not sure if I understand the significance. I apologize in advance for not knowing the difference in advance.

Tejas Limited Series Production - 7 took off for its maiden flight from HAL airport at 4:27 pm on 9th March 2012. This test flight is significant for the programme, as LSP -7 build standard is close to the initial operational clearance (IOC) standard. Accordingly LSP -7 aircraft, along with LSP - 8 will be offered to the Indian Air Force for user evaluation trials (UET). The flight was also significant considering the fact that for the first time Production Test Schedule was used for the first flight of a LSP aircraft in this programme. This is also the first time maiden flight of a prototype was not accompanied by the customary ‘chase’ aircraft, which is an indicator to the level of confidence in the machine.

The flight lasted 28 minutes with Gp Capt KK Venugopal at the controls in the cockpit and Wg Cdr Kabadwal of the National Flight Test Centre (NFTC) as Test Director in the telemetry. During the test flight, performance of the aircraft systems including Multi-mode Radar (MMR), Helmet Mounted Display System (HMDS), Auto-pilot and Instrument Landing System (ILS) was satisfactory, providing a moment of pride for all the stake holders which include ADA, HAL, IAF, CEMILAC, DG AQA, ADE and NAL among others.

Congratulations Team LCA!

MMR, HMDS, ILS and Auto-pilot included from day one. No chase aircraft. No dummy missiles needed for first flight.

LSP-7 was supposed to have been put together using the large-scale production process. The fuel and hydraulic line issue probably detracted from that effort. Nevertheless, I look forward to quicker rollouts from now on.

Uttam · Post by **Uttam** » 09 Mar 2012 21:05

Awesome. Kudos to the Team LCA.

The second picture of LSP-7 in flight show retracted landing gear. I thought, usually they don't retract the landing gear for the first flight as a safety measure. (Of course, I may be totally off-base, so please correct me.) This show the level of confidence of Team LCA.

Only for early prototypes when the system is not yet proven.

Lalmohan · Post by **Lalmohan** » 09 Mar 2012 21:21

since this is close to a production aircraft, its flight test should reflect that fact

Congrats DRDO

India's light fighter 'Tejas LSP - 7' makes first flight

Is this the first time a press release has mentioned a specific aircraft having flown with MMR?

suryag · Post by **suryag** » 09 Mar 2012 23:04

Congratulations too all involved. DRDO/HAL tussi great ho. Raghuk garu thanks for feeding the curiousity of jingoes in this thread and Gurneesh ji nice cartoon

Flying without a chase aircraft shows some good confidence by the pilot and the DRDO/HAL team

Btw a jingo is not a jingo if he doesnt ask for info. There seems to be scanty information on the capabilities of LSP7 why cant HAL address them and then when LSP8 would be ready to fly, last time around LSP3,4 &5 fly within six months.

Raghuk garu, I had this question in mil av thread, there has been no news since the crash of the IJT last year. How are we doing on that program

not sure if the paints are naturally yellow due to their protective agents or are yellow to allow visual inspection of coverage and flaking - probably the latter

Why would you coat the skin panels in yellow to protect the airframe underneath? Most of the LCA's skin panels are carbon composites.

The more I think about not having a chase aircraft, the more it seems to me that it has less to do with the safety or precaution and more to do with chase aircraft filming and observing the new aircraft. I guess since the LCA program has advanced so much that there is no need to do that any more and therefore no chase aircraft. I wonder what can a chase aircraft do if something really goes wrong with new aircraft!
