iDEX DISC 12 (Re-Open) – IAF

The iDEX DISC 12 (Re-Open) challenge is a focused initiative under the Innovations for Defence Excellence (iDEX) framework, managed by the Defence Innovation Organisation (DIO) within the Ministry of Defence. This re-opened challenge is specifically designed to address a critical operational requirement of the Indian Air Force (IAF), inviting MSMEs, startups, and individual innovators to develop a Helicopter Electronic Glide Path-based Landing System.

The primary objective of this challenge is to overcome current limitations in helicopter landing operations, especially in difficult terrains and low-visibility conditions. Existing methods heavily rely on visual cues, which restrict safe landings during adverse weather. The IAF is seeking a novel, transportable, and configurable system that can generate an electronic glide path for helicopters.

Key requirements for the proposed solution include the ability to provide electronic glide path signals, support non-standard glide path angles, and incorporate built-in failure monitoring and degradation alerts. The system must also be compatible with existing aircraft Instrument Landing Systems (ILS) and capable of generating visual or aural warnings in case of system failure. Innovators are encouraged to explore new ground-based equipment concepts.

The expected outcome is a deployable prototype that can significantly enhance safe helicopter landings in challenging environments. The solution should also demonstrate adaptability for future use with transport-class aircraft operating from Advanced Landing Grounds or similar airstrips.

• Grant funding available up to ₹1.5 crore.
• Focus on defence innovation for the Indian Air Force.
• Develop a helicopter electronic glide path landing system.
• Open to MSMEs, startups, and individual innovators.
• Managed by the Defence Innovation Organisation (DIO).
• Application deadline is March 9, 2026.

This innovation challenge is open to Indian MSMEs, startups, and individual innovators.

Applicants must be focused on developing advanced defence solutions that directly address the problem statement issued by the Indian Air Force. The proposed solution must be a Helicopter Electronic Glide Path-based Landing System designed to improve operational capabilities for the IAF.
