Five Winter Flying Tips for Operations at Smaller Snow-Country Airports
Dec. 30, 2016
Thorough flight planning is essential for business aircraft safety year-round, but flying in winter into smaller airports in snow country poses special challenges. These facilities often have small staffs with less snow removal equipment than larger airfields. Some tips for safe winter flying include: reviewing the FAA's Takeoff and Landing Performance Assessment, confirming avionics are compatible with the airport's approaches and handling a cold-soaked plane carefully. Aeronautical decisions must be based on sound knowledge of aircraft performance data and complete weather information, said Jeff Hansen, chair of the Utah Business Aviation Association. "Snow country airports usually equal shorter runways and higher elevations that affect performance." Read more.

Pay It Forward With PIREPs

Operators: NBAA Can Help Prepare You for Hurricane Season
June 1, 2015
While the 2015 hurricane season is forecast to be relatively quiet, NBAA Air Traffic Services (ATS) Weather Specialist John Kosak said no one should be complacent about hurricane season, in spite of the low number of predicted storms. "I encourage all NBAA Member operators to subscribe to NBAA Airspace/Airport Alerts before we enter prime hurricane season," Kosak said. When a large storm is expected, the FAA stands up its Event Management Center (EMC), a facility that coordinates a number of federal, state and local agencies during and after a disaster or other significant aviation-related event. When the EMC becomes operational, ATS personnel send out storm-related airspace alerts, and closely monitor EMC activities in order to keep NBAA Members informed.
