Accessing and calculating holdover times is now easier with the APS Holdover Times app.

The app provides the most recent aircraft ground de/anti-icing fluid holdover times and related guidance published by Transport Canada, the Federal Aviation Administration (FAA), and the Association of European Airlines (AEA).

The iOS app for iPad and iPhone enables easy electronic access to holdover time documents through the PDF viewer and a new way to determine holdover times through a holdover time (HOT) calculator.
