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 holdover time calculation.

The app aims to facilitate the determination of HOT by offering a smart, user-friendly and intuitive interface for the entry of all data points that could impact a holdover time. As inputs are completed, corresponding fields update automatically to ensure that HOTs are easily to calculate and accurate.

Users can also select the regulatory agency for which they require HOTs; FAA and Transport Canada.

Features include:
1- Deicing holdover 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 holdover time.
4- Timer will alert the user when the minimum and maximum HOT expire.
5- Built-in timer allows users to easily see their remaining holdover time and be alerted when the time is set to expire.
6- Notes and cautions of the tables used for the holdover time 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- Ability to work offline.
10- 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.
