It’s still the best 4th generation fighter jet in the world for these reason
Advanced Avionics: Tejas is equipped with advanced avionics, including a modern glass cockpit, mission computer, and radar systems. The aircraft also features an integrated digital flight control system and an advanced data link, which enables it to operate effectively in network-centric warfare environments.
Weapon Systems: Tejas is equipped with a wide range of weapons systems, including Beyond Visual Range (BVR) missiles, precision-guided munitions, and electronic warfare equipment. The aircraft's weapons systems are highly accurate and reliable, making it an effective air-to-air and air-to-ground combat platform.
Stealth Features: Tejas incorporates several stealth features, including radar-absorbent materials and reduced radar cross-section. These features make it more difficult for enemy radar systems to detect and track the aircraft, increasing its survivability in combat.
Manoeuvrability: Tejas is designed to be highly manoeuvrable, with a high thrust-to-weight ratio and excellent low-speed handling characteristics. This enables the aircraft to perform complex air-to-air and air-to-ground manoeuvres, making it an effective fighter jet in both offensive and defensive roles.
As a neutral observer i can say that Tejas is far superior to F-16 Viper in terms of advanced avionics, stealth features and manoeuvrability, However, F-16 Viper has advantages such as higher speed and range and a long history of combat operations. The superiority of one aircraft over the other depends on specific mission requirements and operational context.
