Winter OPS All-Fluids 2020-21 for iOS

By MR Apps $12.99

Developer's Description

Winter OPS is an Application for De-/Anti-Icing & SNOWTAM Decoding for the winter season 2020-2021.

To ensure operational safety, the holdovertimes won't be usable anymore, once the new regulations have been published in autumn 2021.

Contains all - almost 100 - specific Fluid data based on the FAA, EASA and Transport Canada Holdover Time Guidelines.

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.

iOS 13 dark mode helps you not to ruin your night vision.

Decode the SNOWTAMs for your airports. Enter the Data by either Text input or Picker input, it's your choice.

The Decoder translates the number and letters into plain language and lets you chose the approach Runway to get correct information for your landing.
