Ice on the wings can spell disaster for an aircraft - no matter how thin that ice layer may be.
Detecting that ice before the plane leaves the ground is the focus of a new SAE International aerospace standard: SAE AS5681 - Minimum Operational Performance Specification for Remote On-Ground Ice Detection Systems.
SAE AS5681 specifies the minimum performance requirements of remote on-ground ice detection systems (ROGIDS).
Such systems have been around since the early 1990s, but there was no set of requirements to measure that the ability to detect ice by ROGIDS was equivalent or superior to human visual or tactile capability.
SAE AS5681 addresses those issues and provides the framework for manufacturers to comply with requirements and obtain pertinent regulatory approvals.
"The development of this standard involved some very thorough testing by many experienced and knowledgeable industry people," Frank Eyre, SAE AS5681 sponsor, said.
"The testing showed that under the specification outlined in this document, sensors could detect ice better than people. As a result, we believe this standard can help lead to improvements in safety, and it can also reduce unnecessary turnbacks to de-icing pads."
SAE AS5681 was written and created by SAE International's G-12 Ice Detection Committee.
