Citroen C5 Aircross Plays A Key Role At Kempegowda International Airport: A First In India!
The Kempegowda International Airport in Bengaluru has become the first in India to use a locally modified friction tester based on the Citroen C5 Aircross SUV. This innovation marks a shift from the traditional reliance on imported friction testers at Indian airports.
Previously, airports like Cochin International Airport used imported vehicles such as the Volvo V90 and Saab 9-5 wagons for friction testing. The introduction of a domestically manufactured option at Bengaluru signifies a significant change in approach.
Modifications to the Citroen C5 Aircross
The Citroen C5 Aircross has undergone extensive modifications to serve its new role. It is equipped with specialised tools to assess runway grip levels. A deployable wheel, similar to those used in aircraft, measures traction. Additionally, a nozzle system sprays 1mm of water from a 700-litre onboard reservoir to simulate wet conditions during tests.
This SUV also houses various electronic devices and screens, along with a temperature sensor to monitor runway heat levels. The spacious cabin of the C5 accommodates all this equipment without compromising functionality.
Importance of Runway Friction Testing
Runway friction testing is crucial for flight safety. Slippery runways, especially when wet, can lead to loss of control or extended braking distances. Tests conducted at speeds of 65 km/h and 95 km/h provide data on runway grip, categorised as Good, Medium/Fair, or Poor.
A friction value of 0.5 or higher is generally considered safe. Values below this threshold may trigger warnings through NOTAMs (Notice to Airmen) and could necessitate corrective actions like cleaning or rubber removal.
If you've ever noticed a yellow SUV speeding across an airport taxiway or runway, it was likely conducting a friction test. These vehicles are essential for ensuring runway safety by measuring surface grip under various conditions.
