Holdover Pro

Holdover Pro puts the FAA and Transport Canada holdover time tables and a holdover timer on your iPad and iPhone. Choose the airport, or let the app find the nearest one, and pick your fluid. Holdover Pro reads the newest METAR or D-ATIS, works out the precipitation and the snowfall intensity, and finds the cell in the FAA or Transport Canada Holdover Time Guidelines, whichever your aircraft uses, for your fluid, dilution and outside air temperature. It shows you the official table with that cell highlighted, so you can check the answer at a glance. When fluid application begins, start the clock.
