4.3.2

December 1, 2022

- Added Aircraft Performance Values in the Operations Settings. These are relevant to calculate the LOUT according to the Performance and Aerodynamic Acceptance Values in Tables 54 and following. New Middle Speed Values have been introduced for Fluid III (AeroClear MAX), all the other Fluids only have high and/or low speed Values. *If uncertain whether the aircraft to be treated conforms to the low speed, the middle speed, or the high speed aerodynamic test, consult the aircraft manufacturer. The aerodynamic test is defined in SAE AS5900 (latest version). - Default value is HighSpeed Aircraft Performance - The V Rotate Speeds are only used for allowance time calculations and are not used for the LOUT calculations anymore according to the new regulations. - Updated Snowfall Intensities Decoder to new regulations (now FAA, EASA and TC have been harmonized and all use the same values) - Bugfix in the Snowfall intensities Temperature Selection for Fahrenheit - Added Type I Fluids Sky-Go PG 80 & Safewing MP I LFD 80 Pre-Mix 55% - Added Type II Fluids Ice Clear II & COREICEPHOB Type II - Added Aeroclear Max values for Medium Speed Aircraft - Added new Weather Type of Ice Crystals mixed with Freezing Fog, Ice Crystals mixed with Freezing Mist and Snow mixed with Ice Crystals - 4.3.1 was not showing any Holdovertimes for SAE Types I, II, IV - this has been fixed now

4.3.0

October 5, 2022

Initial Update for the 2022-23 Winter Season. Focus has been set on the update of Hold Over Times and DSHOTs. The new Fluids and Weather categories, as well as the SNOWTAM Converter will follow in the next few days.
More

4.2.0

October 29, 2021

Added degree-specific holdover times (DSHOT) The DSHOT database is an extension of the FAA and TC HOT Guidelines. The data it contains is derived from the same natural snow test data that is used to calculate the snow HOT values within the standard HOT tables. Within a typical HOT table, HOTs are provided for defined temperature ranges (e.g., -3°C to -8°C). The HOTs provided within a given temperature range are based on the coldest temperature of that range. Within the DSHOT database, specific HOT values are provided for each Type II, III, and IV fluid at all temperatures decrementing down to a given fluid's LOUT. A 1°C safeguard is incorporated in all DSHOT calculations The DSHOT take into place if the flaps were deployed at the time of deicing/anti-icing, provided the correct selection has been made in the HOT Screen. Any operator making use of the DSHOT data in a modified format shall employ a detailed verification process to ensure that the data presented is accurate and complete. This verification process shall consist of a series of manual checks of the DSHOT data within a DSHOT data presentation (e.g., a modified paper table or an eHOT app) against the corresponding values published in the most recent FAA DSHOT database publication. A record of the verification process shall be kept and maintained and this record shall clearly demonstrate that all DSHOT values within a data presentation have been verified. The verification process shall be updated and/or repeated on an annual basis (or whenever the DSHOT database or its data presentation is updated, whichever comes first). Due to this requirements, the DSHOTs must be actively enabled in the settings (Operations Page), where the user gets presented with the requirements and will be asked for an acknowledgement. If you need assistance in the verification process, please contact inquiries@mr-apps.ch and we'll gladly help.

Description of 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 ********************************** Features: • FAA / EASA / Tranport Canada • Weather condition selection • Weather intensity selection • Flapsettings • Wingsurface • Precipitation Speed • Rotation Speed • Temperature setting (Slider / Buttons / °C / °F) • Fluid / Water Mixture selection • Fluid selection (incl. overview of all fluid HOTs) • HOT Display • Start Time settings (UTC / Device Time) • End Time settings (UTC / Device Time / Countdown) • Application Guidelines (1-Step / 2-Step / all Fluids / all Temperatures) • Qualified Fluids (lists the fluid names included by FAA or TC) • Weather Definitions • De-/Anti-Icing Terms & Definitions • E-Mail De-/Anti-Icing Information to OPS • Light & Dark Color Scheme (iOS 13+) • Warning Levels (Initial Warning / Last Warning / Expiry) • Individual Notification Settings • SNOWTAM Decode with Global Reporting Format • Snow Intensity / Visibility Decoder • iPad supports both orientations / iPhone only portrait. ********************************** If you find any mistakes in the program, please contact us at info@mr-apps.ch, we will then rectify the error immediately. We are also happy to integrate user requested new features. Some more Information you can find on our website: www.mr-apps.ch If you require a template for integration into your Winter OPS Guide, please contact me at info@mr-apps.ch, I will then send you the documentation. ********************************** NOTE: This Application reflects general recommendations only and local airworthiness agencies’ rulemaking and guidance as well as aircraft manufacturers’ documentation must always be followed. 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.
