Break the Ice

Most general aviation aircraft do not posses proper equipment to aid in de-icing tactics. So, how can we safely deal with ice as GA pilots in non-FIKI aircraft? Here are some things to note:

• Though temperatures can reach freezing, ice will not form unless there is visible moisture in the air.

• Freezing levels are not a contiguous layer. Freezing levels can be higher or lower at any given altitude, and they can drop down lower than forecast.

• Weather is ever-changing and dynamic. The best way to avoid icing conditions is to play it safe regarding all types of weather pushing through your area or enroute.

• A general rule of thumb suggests pilots stay a minimum of 1,000 feet, if not 1,500 feet, below any known icing levels, particularly if there’s rain present.

• Aircraft can still build ice in near-freezing temperatures, as super-cooled droplets can freeze on contact with aircraft surfaces that are below freezing.

AKS Chief Instructor Scott Settle recommends partaking in a thorough weather briefing prior to takeoff by calling 1-800-WX-BRIEF. It is possible to use weather briefing services within the Foreflight and Garmin Pilot applications, but Scott urges pilots to call for a thorough weather brief despite these applications’ abilities.
