Lateral

The most advanced EFB, built with revolutionary safety capability for low-level flight — and a complete ecosystem to accompany it.

Terrain, obstacles, airspace and TFRs on one dark chart, drawn to stay legible in daylight at five hundred feet. Download the region and the whole thing works with no signal at all.

10.3 million obstacles, alerted by direction and closing speed rather than a beeping radius — and after the warning, it shows you which wire.

Routes that understand elevation and turbulence, with a vertical profile of what you will clear and what you will not.

METARs, TAFs and winds aloft along the whole route, not just at the two ends of it.

85,616 airports and 6,070 heliports: diagrams, frequencies and runway data — plus the owner's phone number on US helipads, for when the question is who to call for permission to land.

Your aircraft's real envelope, checked before you lift, with the numbers written straight into the record.

Hours that fill themselves in from the flight you just flew — including external load and night vision time.

Fly the track back afterwards: altitude, groundspeed and every alert that fired, for debriefs and for training.

Sentry, Stratus, Stratux and GDL 50 — sub-second direct reception, drawn on the same map, plus TIS-B and ADS-R the internet cannot see.

Write the clearance down the way you already do — a pre-ruled ATIS pad you can scribble on with a finger, and clear with one tap.

Download the region before you go. Maps, obstacles, terrain and airports all work with no signal at all — which is where the job usually is.

Draw straight onto the map with a finger — a boundary, a search pattern, the bit of ground you are working. One finger draws, two move the map, and it saves with the flight.

The Lateral moving map: a dark chart dense with colour-coded obstacle and power-line spans.A live POWER LINE alert on the Lateral map at 0.49 nautical miles: the ownship turns red, the span ahead is highlighted, and the alert arc lights on the side the hazard is on.Weather at Portland Troutdale in Lateral: wind, visibility, ceiling, altimeter, temperature, dew point and density altitude, the raw METAR under them, and a TAF-driven forecast graph.Portland Troutdale in Lateral: field diagram, fuel available, CTAF and ATIS, runway dimensions with the favoured end, and the full frequency list.A Lateral weight and balance result: within limits from takeoff to landing, with weight, CG and lateral CG checked at both ends.The Lateral logbook: running totals for time, PIC, night and landings, then each flight with its route and aircraft — the ones recorded in the app carry a play button back to the replay.ADS-B traffic drawn on the Lateral moving map.Lateral's offline maps: terrain, chart, hazards and airspace downloaded per area, with 17,905 airport diagrams already stored on the device.

One feature among many. The one nobody else has.

The Hazard Alert Engine.

It watches everything below two thousand feet — and only speaks when something crosses your path.

See how it thinks +

It says it out loud. A spoken callout names the hazard, its bearing and how far — so your eyes never come inside to read a screen.

And it stays on the Island. Bearing and distance live at the top of the phone, updating, whatever app you are in.

Lateral's Dynamic Island widget monitoring quietly: a green arc, nothing ahead. The same widget alerting: POWER LINES, bearing 114 degrees true, 0.11 nautical miles.

One database · both worlds

The map follows the light.
The wires never leave.

Night: the dark map rendering every obstacle span in the area with a live power line alert. Day: the light map, same obstacles, with the directional alert cone ahead of the aircraft.
Night ops

Dark map, dense wire country.

The Flight tab renders every span around you — ownship, radius rings, the full network. When one threatens your path, the banner fires.

POWER LINE — 0.10 NM
Day VFR

Daylight. Same wires.

The directional cone narrows and points ahead as speed builds, and opens back up when you slow.

Plan

Plan at a desk, fly on the iPad. The same planning brain, on a full-size screen — routes, terrain, weather and briefs that sync straight to the aircraft.

Lateral Plan in the browser: a route from Portland-Troutdale to The Dalles across the Columbia Gorge, with distance, time en route, the highest thing under the route and clearance beside it, obstacles marked across the map, and a terrain profile along the bottom.
Available now

Fleet

Hours, maintenance, currency and obstacle exposure — per airframe and per pilot, straight from the flights your crews already fly.

In beta

Schedule

Aircraft, instructors and students on one calendar. Double-booking is impossible, and the schedule knows the day each airframe grounds.

Private beta

Weather

Forecasting the first two thousand feet — mechanical turbulence, rotor, valley fog. The layer everyone else barely resolves.
