The details that make a difference

Screens show the app interface; language and example data may differ.

01°C → ft

See the whole approach. Including the cold.

Turn altitude entries and outside temperature into a visual approach profile. See the corrected levels together with distances, vertical speeds and the descent path, instead of keeping a separate mental picture for every number.

02METAR

Your next approach starts with the last one.

Save airport and approach entries, select a runway and bring METAR into the same workspace. Return to a familiar setup and review the current weather without rebuilding the whole profile.

03HOT

The fluid. The conditions. The time. Together.

Choose the fluid type, concentration and weather conditions. See the holdover time range, start the timers and keep deicing frequency, location and remarks alongside them. The supporting information stays close to the decision.

04FAA

A number is only useful with its context.

Open the full holdover table with its temperature bands, concentrations and numbered notes. Follow the original FAA reference and check the source edition: the conditions and limitations belong with the result.

05Light / Dark

One workspace, from briefing to night operations.

Switch between light and dark presentation while keeping the same layout. Weather, runway information and your selected deicing context remain together, with less hunting through unrelated screens.
