Where’s the ice?

Goodrich Corporation has unveiled its new IceHawk wide area ice detection system.

The system provides real-time images of frozen contaminants on aircraft surfaces and will be available in January 2002.

IceHawk systems are available for de-icing trucks using either open buckets or enclosed cabs. Enclosed cab designs allow the operator to obtain and analyse icing images without leaving the cab. The IceHawk system is the only on-ground, wide area ice detection system approved by the FAA to replacetactile inspection requirements.

In operation, the IceHawk system scans a surface by sending a beam of polarised infrared light. It detects ice by analysing the polarisation of the reflected signal. When ice is present, the returned infrared signal is unpolarised. A picture of the scanned surface is computed and shown on the IceHawk display with patches of contamination highlighted in red.

The system has the ability to ‘see through’ materials such as de/anti-icing fluid, hydraulic fluid and fuel to detect frozen contaminant build-up underneath.

The system can detect any frozen contaminant including snow, frost, slush or ice.
