Never seen ice meself but this info may interest others:
"... This test’s purpose has two major outcomes:
certifying the Norwegian drag-chute and demonstrating that the
entire fleet of F-35As are capable of landing at a runway condition reading (RCR) of 7. The RCR scale is based on how wet and dry each runway is. A RCR 23 is considered a dry runway while an RCR 5 is compared to landing on ice.
“The F-35A is currently certified to land at an RCR of 12,” said Capt. Daniel Campbell, the 354th Fighter Wing F-35 PIO director of mission support. “This test is important to the base because it will help
certify the F-35A to operate at an RCR of 7. The 354th Civil Engineer Squadron and 354th Operations Support Squadron try to keep our runway at an RCR of 12 or better during the harsh winters, but often are below that. We need the lower RCR certification to ensure the F-35A can operate throughout our winters.”..."
