About this app

Winter OPS supports aviation professionals during winter operations with fast access to Holdover Time information, De-/Anti-Icing guidance and SNOWTAM decoding — all in one purpose-built application.

Configure the relevant operational conditions, select the applied fluid and quickly determine the corresponding Holdover Time (HOT). Compare available fluids at a glance and monitor the remaining HOT with configurable warnings and notifications.

KEY FEATURES

HOLDOVER TIMES
- Access Holdover Time (HOT) information based on supported FAA and Transport Canada guidance
- Configure weather condition and precipitation intensity
- Select outside air temperature in °C or °F
- Configure fluid type and fluid/water mixture
- Compare HOT values for available fluids at a glance
- Consider operational parameters including wing surface, flap setting, precipitation speed and rotation speed
- Display HOT start and end times using UTC, device time or countdown
- Degree-Specific Holdover Times (DSHOT) available where permitted by your operator procedures

HOT MONITORING
Keep track of your remaining Holdover Time during winter operations.
Configure individual warning levels for:
- Initial Warning
- Last Warning
- HOT Expiry

DE-/ANTI-ICING REFERENCE
Quickly access useful operational reference information including:
- One-step and two-step application guidelines
- Application guidance by fluid and temperature
- Qualified fluid information
- Weather definitions
- De-Icing and Anti-Icing terminology and definitions

SNOWTAM & WINTER WEATHER
- Decode SNOWTAM information using the Global Reporting Format (GRF)
- Snow intensity and visibility decoder
- Present complex winter operations information in a clear and structured format

DESIGNED FOR AVIATION OPERATIONS

Winter OPS is designed for pilots, flight operations, dispatch, ground operations and De-/Anti-Icing personnel who need relevant winter operations information without navigating through multiple documents and tables.

The interface is optimized for quick access to operational information and can be configured according to individual requirements.

Additional features include:
- Light and Dark Mode
- Configurable notification settings
- UTC and local device time support
- De-/Anti-Icing information sharing with Operations
- Portrait and landscape support

DATA & GUIDANCE

Winter OPS uses Holdover Time data and guidance published for aircraft ground De-/Anti-Icing operations, including FAA and Transport Canada information and relevant EASA guidance.

Applicable data is provided through annual subscriptions.

Operators must always verify that the applicable data, procedures and winter season are approved for their operation.

IMPORTANT

Winter OPS is an operational reference and support tool. It does not replace operator procedures, aircraft manufacturer documentation, applicable regulations or the professional judgement and responsibility of flight and ground personnel.

Local authority requirements, operator documentation and aircraft-specific procedures must always be followed.

What’s new

Walkthroughs - Holdover Times, Application Guidelines, SNOWTAM Decoder, Snow Visibility

Snowfall rate
The Holdover page now explains the precipitation rate behind the selected intensity — tap Rate above the arrows.

DSHOT values
SAE Type II, ABC-K PLUS and FCY-2 now correctly show the light/moderate precipitation intensity.

Settings - Several settings now say what they decide, and the pages they sit on are easier to work through.
Design improvements and minor bug fixes throughout.
