01 / THE WORKFLOW
Designed to make the next useful piece of information easy to find, without crowding the calculation.
Enter conditions manually or use the app's weather input tools. Snowfall intensity is derived from relevant visibility and day/night conditions when applicable.
Choose the fluid and applicable dilution. Temperature and fluid limitations stay connected to the result.
Valid states remain quiet. Prohibited conditions are explained next to their cause, with no ambiguous green result to distract from the warning.
Follow remaining holdover time, view the start and expiry in local time or UTC, and update weather during the session.
02 / THE INTERFACE
Real screenshots from the current iPhone interface. Select a screen to view it at full size.
Screenshots illustrate example inputs and app behaviour, not operational authorization or a guarantee of a particular HOT.
03 / THE APPROACH
HOTmate follows a deliberately quiet design language: fewer choices at once, values more visible than labels, and color reserved for meaning.
04 / DATA & RESPONSIBILITY
The embedded HOT reference dataset is based on the FAA Holdover Time Guidelines, Winter 2026–2027 (original issue: August 11, 2026), subject to the applicable general information, source limitations and operator-specific procedures.
HOTmate is not affiliated with or endorsed by the FAA, any airline, aircraft manufacturer or regulator. It is intended only to cross-check your own calculations, never as the sole basis for operational decisions.
