Skyslice

For iPhone · Student and VFR pilots

See the weather on your route. In 3D.

Skyslice turns the latest NOAA HRRR forecast into a slice of sky along your exact route: every cloud layer, icing, turbulence and the freezing level, over real terrain. Fly it before you fly it.

Skyslice overview of a route from Denver to Aspen: the Rockies in 3D with forecast clouds above them.

What you see

Everything between you and your destination.

A forecast you can look at from every angle: from the cockpit, behind the plane, or the whole route at once. Press play and watch it unfold.

Clouds in 3D

Bases, tops and layers from the 3 km HRRR model, drawn as real volumetric clouds along your path.

Know where it turns IFR

The route bar is coloured VFR, MVFR, IFR and LIFR, mile by mile, for now and the next three hours.

Icing and turbulence

Where icing and turbulence are likely, derived from the forecast, and the freezing level, right where you would fly through them.

Your altitude, checked

Skyslice compares each VFR cruising altitude with the cloud-clearance rules and suggests one.

Your minimums

Set your personal ceiling, visibility, wind and crosswind limits. Skyslice shows where the route breaks them.

Runways and crosswind

The best runway for the wind is picked for you. Tower gave you another? One tap and everything updates.
