Snow removal equipment will add to the congestion on already busy airport surfaces. Runways and taxiways will be alternately closed and reopened. The controller will have to be that much more alert to prevent conflicts between vehicles and aircraft operating on the runways. Remember, too, that snow and ice present more hazards to aircraft than hazardous braking on slippery surfaces. Loose snow or ice ingested into aircraft engines can cause serious damage.
Propeller blades that strike snow banks can be easily bent and damaged beyond use.
Blowing snow can obscure aircraft from your view too. Those of you who are laughing at the snowbelt guys and gals don't get off easy either. Ice is more prevalent aloft in those layers of stratus clouds and yes, Key West, thunderboomers too. Share such information with other pilots and controllers as appropriate. If we all work hard at raising our awareness during this time, we can be assured of a safe, happy, holiday season.
