The 'Vayu Link' communication system is an advanced system developed specifically to assist pilots in maintaining continuous and reliable communication with their base stations, especially during adverse conditions such as poor weather or technical challenges.
Step 1: Understanding the system
Maintaining communication is critical for flight safety, and systems like 'Vayu Link' ensure that pilots can stay connected without interruption.
Step 2: Developer identification
The Indian Air Force, which operates and manages military aviation and related systems, has developed this technology to enhance operational efficiency and safety of its pilots.
Step 3: Why other options are incorrect
- ISRO is mainly involved in space research and satellite launches, not specifically in pilot communication systems.
- Hindustan Aeronautics Limited manufactures aircraft but is not credited with developing this system.
- NTRO (National Technical Research Organisation) is an intelligence agency, unrelated to pilot communication systems.
Hence, option (B) is the correct answer.
