Deicing Holdover is a winter operations productivity tool designed with airline pilots' needs in mind. It can calculate a de/anti-icing holdover time based on user-generated inputs, with options to enter all values that could impact a HOT calculation. Users can select the regulatory agency for which they require HOTs; FAA, Transport Canada, and AEA tables are all available.

Features include:

1- Deicing hold over calculator based on user input for weather and fluid.
2- Digital versions of the HOT guidelines in PDF format.
3- User friendly timer based on the calculated hold over time.
4- Timer will alert the user when the minimum and maximum HOT expire.
5- Timer will continue to run in the background when user exits the application.
6- Notes and cautions of the tables used for the HOT calculation are accessible from the Calculator page.
7- User will be prompted to select prevailing visibility to determine snow fall intensity only when required.
8- Ability to reset user input.
9- Flaps up/down data.

Deicing Holdover is part of the Deicing Manager software suite, a web-based solution that streamlines the capture, storage, and analysis of all raw operational data needed to manage aircraft deicing operations. Deicing Manager's on-demand analytics portal converts this data into actionable information.
