About Holdover Calculator
Holdover Calculator is a pre-departure decision tool for pilots facing winter operations. It returns the applicable anti-icing holdover or allowance time from FAA or Transport Canada published guidance, based on the actual weather, the de/anti-icing fluid applied, and your aircraft configuration. DESIGNED FOR iOS 26 Built for iOS 26 and its Liquid Glass interface. The pilot answers a sequence of focused questions; the app shows the matching table cell, the published range, and a continuously interpolated estimate within that range. KEY FEATURES • Holdover and allowance times from the current FAA Holdover Time Guidelines and Transport Canada HOT Guidelines — and if a correction is published mid-season, the app can pick up the new numbers on its own. Settings shows which set you are calculating with. • Live weather autofill via the NOAA Aviation Weather Center — closest METAR or any ICAO you search. • Manual entry always available when stations are out of range or you want to model conditions ahead. • All four fluid types (Type I through Type IV) with both generic-table and specific-brand selections. • Active Frost allowance and Ice Pellet allowance with a 90-minute takeoff-window tracker. • Chart Notes surfaced inline, with active conditions (cold-soaked wing, OAT thresholds, etc.) flagged so you see only the notes that matter right now. • App Estimated time — a continuous interpolation across OAT and precipitation intensity, shown alongside the FAA Recommended low e
