Winter OPS is an Application for De-/Anti-Icing & SNOWTAM Decoding.
The data is based on the FAA, EASA and Transport Canada Holdover Time Guidelines for Winter 2025-2026 and are available through yearly subscriptions.
Degree-specific Hold Overtimes are available if your operation allow their usage.
According to the EASA Safety Information Bulletin SIB 2017-11 the FAA Holdover Time Guidelines are to be used instead of the previous AEA Guidelines.
With Winter OPS you can not only easily find your hold over time, but also set an alarm to warn the approaching expiry of the HOT.
With just one glance you get an overview what HOT other fluids would have, then choose the required or sprayed fluid to get your HOT.
Find useful information such as qualified fluids, weather definitions, anti/de-icing definitions & application guidelines.
Dark mode is supported and helps you not to ruin your night vision.
Change the settings to meet your requirements.
Terms of Use are available on: https://www.mr-apps.ch/wops/termsandconditions.html

As individual icing situations or aeroplane types/models may require special procedures, this application can never replace the responsibility of the aeroplane operator’s judgement. The responsibility for the correct de-icing/anti-icing of aeroplanes always stays with the operator of the aeroplane. Although great care has been taken by the developer, errors or misprints can occur for which neither the developer nor the FAA/TC (information source) can be held liable. The developer or the FAA/TC (information source) do not accept liability for any damage, personal injury, death or any other negative effect that may result from the use of the information contained in this application as a whole or parts thereof.
