A contingent of U.S. Air Force flight attendants participated in this year’s NBAA Flight Attendants/Flight Technicians conference, not just to learn from their peers but to share their own experiences using dry ice as a cooling medium to keep food safe on long trips. It turns out that a sufficient quantity of dry ice allows for weeks of operation and proper food storage. There are important safety considerations when using dry ice.

As airports across the U.S. wage their annual struggle against winter weather, business aviation operators may soon find themselves familiar with a new de-icing method. Forced-air de-icers, which use high-volume, low-pressure air to help strip contamination from flying surfaces, have been used to augment the effect of glycol on airliners at major airports for years, but the business aircraft community has been slow to embrace them.
