URBAN AIR MOBILITY · QUIET ELECTRIC VTOL

Cleared for a quieter sky.

Hangar 12 flies electric vertical-takeoff aircraft between city vertiports. Four seats, one pilot, sixty-two decibels — booked like a car, boarded in minutes, flown over the traffic instead of through it.

[ 01 · FLIGHT ARTICLE H12-A4 ]SHT 02 / 06

One airframe. No single point of failure.

The H12-A4 is a lift-and-cruise design: a fixed wing does the flying, four independent electric rotors do the taking off. Fewer moving parts than a helicopter, and every one of them has a backup.

Twelve minutes, not fifty-eight.

Five vertiports across the metro, city-pair service on a published timetable. Your seat holds to the minute — the road below does not.

[ 03 · PERFORMANCE ]SHT 04 / 06

Quiet is a specification.

0dB(A)flyover at 100 m — a conversation, not a helicopter

0kmrange with full diversion reserve

0minmedian vertiport-to-vertiport hop

0kg CO₂emitted in flight — every flight

Noise measured per ISO 3744. A conventional light helicopter at the same point: 78–82 dB(A). The difference is why we are allowed downtown.

[ 04 · SAFETY & CERTIFICATION ]SHT 05 / 06

Boring by design.

Everything interesting about the H12-A4 happens on the drawing board, so nothing interesting happens in the air.

Distributed propulsion

Four independent motor–rotor channels on isolated power buses. The craft holds a stable hover with any single channel out — the certification basis assumes it, and the flight-test campaign has demonstrated it.

Triple-redundant flight control

Three dissimilar flight computers vote on every command, two hundred times a second. A disagreement grounds the disagreeing unit — not the aircraft.

Battery architecture

Eight isolated packs with cell-level fusing and vented containment. Reserve energy for a go-around plus a diversion is a hard floor — never touched in scheduled service.

Whole-aircraft recovery

A ballistic parachute covers the low-altitude envelope that autorotation never could. Below 120 m, the airframe itself is the last redundancy.
