Have you ever noticed a bright yellow SUV speeding down an airport runway? If so, you likely spotted a friction test vehicle—a crucial part of aviation safety. Bengaluru’s Kempegowda International Airport has taken a major step forward by introducing India's first domestically manufactured friction tester, based on the Citroen C5 Aircross. Until now, Indian airports primarily relied on imported friction testers like the Volvo V90 at Cochin International Airport. This marks a significant shift towards indigenous technology in aviation safety.
What is a Friction Tester and Why is it Important?
A friction tester is a specially modified vehicle designed to measure the grip levels on an airport runway. These tests are vital to:
- Ensure safe landings and takeoffs.
- Prevent aircraft skidding, especially in wet conditions.
- Help authorities monitor runway conditions and take corrective actions.
Friction testing is conducted at speeds between 65 km/h and 95 km/h, with results categorized into:
- Good – Safe for landing.
- Medium/Fair – May require extra caution.
- Poor – Unsafe; requires immediate action.
If friction values drop below 0.5, a NOTAM (Notice to Airmen) is issued, warning pilots of potential runway hazards.
How is the Citroen C5 Aircross Modified for Friction Testing?
The Citroen C5 Aircross is no ordinary SUV anymore. It has undergone major upgrades to perform its new role efficiently:
- Deployable Friction Testing Wheel
- A special wheel, similar to aircraft landing gear, measures traction levels on the runway.
- Onboard Water Spraying System
- A 700-litre water reservoir sprays a controlled 1mm layer of water to simulate wet runway conditions.
- Advanced Electronic Monitoring Equipment
- Temperature sensors track runway heat levels.
- Multiple screens and data collection tools analyze friction readings in real-time.
- Spacious Cabin for Equipment
- The large interior of the Citroen C5 allows for seamless integration of monitoring tools without affecting its mobility.
Why This Innovation Matters
The introduction of a locally manufactured friction tester in India is a game-changer for several reasons:
- Reduces Dependence on Imports
- Previously, India relied on imported vehicles like the Volvo V90 and Saab 9-5 wagons.
- Cost-Effective Solution
- Locally modified vehicles are cheaper and easier to maintain.
- Enhances Aviation Safety
- Faster and more efficient friction testing ensures safer takeoffs and landings, even in adverse weather.
Conclusion
With the Citroen C5 Aircross taking on this critical aviation role, Bengaluru Airport has set a new benchmark for safety in India. This marks a shift towards self-reliance in aviation technology, ensuring better efficiency, cost-effectiveness, and improved runway safety. As more airports adopt similar solutions, India’s aviation infrastructure will continue to evolve for a safer future.
