Winter operations demand precision. When de-icing fluid is applied to an aircraft, the clock starts ticking — and every pilot needs to know exactly how much hold-over time (HOT) remains before protection expires. No-ICE is a new iOS app built specifically for professional pilots who need fast, reliable access to deicing hold-over time tables from the FAA and Transport Canada (TCA), combined with a precision timer that tracks every second in real time.
Available now on the App Store, No-ICE removes the complexity from hold-over time management during cold weather operations — no manuals, no guesswork.

Why Hold-Over Time Matters for Flight Safety
Hold-over time is the estimated period during which a de-icing or anti-ice fluid remains effective after application. Exceeding it means ice can re-form on critical aircraft surfaces — wings, stabilizers, control surfaces — compromising safety during taxi and takeoff.
Pilots operating in winter conditions must constantly reference HOT tables, cross-referencing fluid type, outside air temperature, and precipitation type. Doing this manually under time pressure, often in challenging conditions, introduces risk. That is the problem No-ICE was designed to solve.
Official FAA and Transport Canada Data
No-ICE provides direct access to hold-over time tables from two authoritative sources:
- FAA — Federal Aviation Administration holdover time guidelines
- TCA — Transport Canada de-icing standards
The app covers Type I, Type II, Type III, and Type IV de-icing and anti-ice fluids, across all relevant weather conditions:
- Snow (all intensities)
- Freezing rain
- Freezing drizzle
- Frost
Multiple fluid concentrations and temperature ranges are supported, giving pilots the same data they would find in official publications — but accessible in seconds.
Precision Timer with Real-Time Tracking
At the heart of No-ICE is a purpose-built timer designed for the cockpit workflow:
- One-tap start, pause, and resume — no fumbling with complex interfaces
- Elapsed time display with UTC/Zulu start time for operational logging
- Assured time (green zone) and Limit time (orange zone) calculated and displayed in real time
- Automatic flaps/slats factor — when flaps are extended, hold-over time is reduced by the standard 0.76 factor, applied automatically
- Haptic feedback for eyes-free operation during high-workload phases
The timer is not just a countdown. It is an operational tool that gives pilots situational awareness of exactly where they stand relative to the assured and limit holdover time windows.
Live Activity and Dynamic Island
No-ICE takes full advantage of Apple is Live Activity and Dynamic Island features. Once the timer is running, pilots can monitor hold-over time directly from the iPhone lock screen — without opening the app.
- Visual progress bar with color-coded assured (green) and limit (orange) zones
- Full red indicator when hold-over time has been exceeded
- Dynamic Island integration for at-a-glance status
This is particularly valuable during taxi operations, when the phone may be mounted or stowed but the lock screen remains visible.
Built for the Cockpit
No-ICE was designed with the operational environment in mind:
- Celsius and Fahrenheit support — switch based on your operational region
- Persistent state restoration — the app recovers its state after interruptions or restarts
- iPhone and iPad compatible
- Lightweight — only 8 MB, fast to load, no unnecessary overhead
Whether you are flying short-haul routes in northern Europe, crossing the Canadian prairies, or operating out of airports in the US northeast, No-ICE provides the de-icing data you need, when you need it.
Who Is No-ICE For?
No-ICE is built for professional pilots — airline, cargo, business aviation, and anyone operating aircraft in winter weather conditions. If you reference holdover time tables as part of your standard operating procedures, this pilot app replaces the manual lookup with a faster, more reliable digital workflow.
It is equally useful for dispatchers, ground crew coordinators, and training departments looking for a clear, visual reference tool for de-icing hold-over times.
