India’s Tejas Light Combat Aircraft is ready to undergo another round of crucial sea trials in Goa.

Sources tell AVIATION WEEK that this time the testing will involve the firing of a missile and the jettisoning of a drop tank. The trials are set to take place this week at Naval Air Station Hansa, Dabolim, in Goa. Tejas successfully completed earlier sea trials in September as part of its Out of Station Flight Test Plan.

Pilots from the Bengaluru-based National Flight Test Center will perform the weapon trials this time.

“The density of air and humidity is very high in Goa. This time during the sea-level trials we are evaluating the radar, helmet-mounted systems and instrument landing systems,” a source said. “We will also test the radar warning receiver.”

In addition to firing a Russian-made R-73 air-to-air missile, the pilots are scheduled to test the safe drop tank separation from the aircraft.

“We have done all the ground-based tests. We are planning four-five drops at various speeds, altitudes and angles of attack,” a source said. “Tejas can carry 5,000 liters of fuel, including 1,200 each in drop tanks [and] 2,400 in wings and fuselage.”

Tejas also can carry two outboard R-73 missiles and two mid-board beyond visual range (BVR) Derby missiles from Israel.

“We have fired an R-73 missile in October 2007 against a zero target. It is important to see the safe separation of the missile,” the source said. Plume separation studies, which involve interaction with a missile’s exhaust, also will be carried out during the trials.

Various Tejas platforms have performed 1,481 flights, clocking about 878 hr. Tejas also has achieved Mach 1.6 at 15 km. altitude and a calibrated air speed of 1,350 kph.

Tejas is scheduled to complete its pre-initial operational clearance requirements by Dec. 27.

You are right and I guess India has realised that, this is why they have launched AMCA! They surely will not scrap LCA because scraping will be an embarrassment!
By the time (may be 2025) India completes AMCA it will be era of 5th geenration fighters thus they started 5th generation project.

India realised that LCA TEJAS MK 1 AND MK 2 are HERE TO STAY For long long time to come . Anyway DO YOU THINK INDIA ORDERS 107 GE414 WORTH 822MILLION DOLLARS FOR DIWALI ROCKETS ?? So Till then enjoy this link mate ,tejas trail over Goa -

hate to pour cold water on critics hahaha

Tejas can drop bomb , fire Missiles, has got decent stuff within it... what makes you think that it is a failed one?

Because they think it dosent have a sustained AoA of 21 degrees. when LCA has a sustained AoA of 20 degrees which is better than MiG 21 Bisons.

LCA loses altitude in tight turns...which is an inherent flaw of the tail-less delta.

LCA is not yet operational.

These are the major arguments that you will face with.

I am not an aviation expert.But I think
TEJAS have AoA 20 degrees just 1 degree short of IAF expectations.This can be fixed along with the development of TEJAS MK-2. Also the problem of loss of altitude will be fixed.
IAF already ordered 40 TEJAS MK-1.

hmmmm what a serious problem ?? cant believe why the people in ADA are still alive by planting such serious problem ..

Yeah....yeah.....Answer to all those critics.....

Livefist - Indian Defence & Aerospace: Tejas LSP-4 Fires R-73 Missile Again

DRDO Statement: As a run up to the impending achieving of IOC and release to service, a Tejas detachment has been operating from INS Hansa in Goa, conducting the last phase of flight trials. One of the main objectives of the current phase of flight trials was clearing the firing envelope of air to air close combat missile from the Tejas. The R-73 missile, which is the chosen air to air close combat missile for the Tejas. The missile is integrated with the on-board Digital Stores Management System (SMS) and Open Architecture Mission and Display Computer. The missile selection is performed from the high resolution Multi Function Display (MFD) pages integrated with the state of the art on-board avionics. All of this equipment form the IOC standard of Avionics.

The test firing was done from the Tejas LSP-4 aircraft, piloted by Gp Capt. George Thomas, Group Director (Flight Test Operations) of the National Flight Test Centre, ADA. The test aircraft was accompanied by a chase Tejas piloted by Gp Capt Suneet Krishna. This critical test was closely monitored and controlled by the Test Director Wg Cdr Toffeen, supported by the safety pilot, Gp Capt (Retd) RR Tyagi, from the mobile telemetry positioned at the test location. The data and video from the test aircraft were also available at the base station in Bangalore through a dedicated fibre optic link set up for this purpose.

This flight test demonstrated the following important requirements of the user:
a) Safe separation of the missile from the test aircraft.
b) No Missile plume effect on the engine operation
c) Avionics and Weapon system functionality and safety interlocks
d) Aircraft Handling quality assessment during missile release
e) Effect of missile plume on the composite structure.

More firings of the missile are planned during the current week leading to CCM firing envelope clearance for the Tejas. The composite team of ADA, HAL, NAL and ADE designers is involved in the planning of the subsequent firing tests. The aircraft are being supported outstation by a composite HAL and IAF team with DGAQA and CEMILAC personnel. The result of this critical test has added yet another feather on the cap of ‘Team Tejas’ and the entire team is looking forward to the successful completion of the balance tasks.
