The Indian Air Force (IAF) has carried out the second phase of hot weather trials on the Tejas light combat aircraft, which is due for initial operational clearance (IOC) by end of 2010.

The second phase of hot weather trials will verify the aircraft in IOC configuration with integrated weapon systems and sensors, according to the Press Trust of India.

During the trials, the IAF used two Tejas aircraft for trial sorties to check out digital flight control computer, avionics systems, multimode radar, RWR and the electrical and environmental control systems.

The test was carried out to verify the aircraft systems under temperature conditions up to 45°C.

Data, video and audio from the test aircraft were transmitted in real time by the air force AFNET to NFTC Bangalore for closer monitoring and detailed analysis.
