Ice*Meister™ Model 9732 is a multi-function OAT gauge that detects ice on a molecular evel, then indicates it to the pilot — within seconds of the penetration — of any icing domain aloft.

Model 9732-OAT

For general aviation, there is no standard to determine when the aircraft has penetrated an icing domain.

For general aviation, there is currently no standard for detecting airframe icing aloft. There is no automation. It’s anyone’s call, and it’s entirely subjective with each pilot.

Unseen airframe icing aloft is both dangerous and perverse — the only time it forms is when you’ve fixated on the instrument panel, flying in visible moisture (IFR/IMC) and not looking outside.

How can you see white (rime) icing when it begins to form on a white wing? And once you do become aware of icing on the wing, for how long has it been accumulating? Has ice accumulated on other surfaces not visible from the cockpit? And, if you have an old ice detector from the 1970s, it’s a power hog and requires 0.025″ of ice before alterting the pilot. That’s a lot of ice!
