Winter OPS

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 2023-2024 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
