Deice HOT tables and the timer, in one place.
Holdover Pro finds your holdover time from the latest weather, your fluid and the outside air temperature, shows you the official table it came from, and runs the clock from the moment fluid application begins. Built for iPad, iPhone and Slide Over beside ForeFlight.
What it does
The holdover time, from the weather
The newest METAR or D-ATIS at the nearest airport, your fluid and the outside air temperature pick the table cell for you. Typed-in weather works too.
FAA and Transport Canada tables
Winter 2026-2027 tables for both, chosen per aircraft. The official table is shown with the cell lit, so you can check the lookup yourself.
A clock you can read at a glance
Green inside the holdover time, amber at the lower value when a contamination check is due, red when it has expired. Alerts and airborne detection included.
Every aircraft, by tail number
Add your aircraft from the FAA registry and keep its holdover rules with it, for any jet or turboprop.
Tables that stay current
Holdover Pro checks for revised tables during the season and downloads them, so you are not flying with last year's numbers.
A record of every holdover
Date, tail number, airport, weather, the table and cell used, fluid and times, saved for every holdover and ready to export.
Holdover Pro is a reference aid. It is not approved by the FAA or Transport Canada and never authorizes a takeoff. Your operator's approved de-icing program and the pilot in command always have the final say.
