Preview only — not a live deployment. Local marketing mockup for Sentinel by Aileronics.

Visual Traffic Collision Avoidance

See traffic. Not just a triangle.

Sentinel by Aileronics is camera-based visual traffic on your iPad — referenced to the horizon — plus portable ADS-B–class features, on a windshield suction mount. One unit for the scan and the cooperative picture — built to replace a portable weather-brick receiver, not sit next to one.

Production Unit base model $1,499 · Targeted availability Q1 2027

ADS-B can’t show you everything.

ADS-B traffic is cooperative. An In-only picture can be incomplete. Traffic displays supplement your outside-the-window scan — see-and-avoid still rules. A cyan triangle or callout is not the same as seeing traffic against the horizon.

Tools supplement the scan. They don’t replace it. FAA guidance frames traffic displays as support for outside-the-window scanning. Cooperative In-only traffic can miss aircraft that aren’t part of that picture. Sentinel is built for that reality: a portable visual layer on your EFB, together with ADS-B–class features — without claiming the sky is fully covered.

V-TCAS — visual traffic on your EFB

Sentinel mounts on the windshield and shows visual traffic on your EFB / iPad in reference to the visual horizon — not a cyan triangle or ATC callout alone — with portable ADS-B–class features in the same system.

Airplanes
Drones
Birds

Camera-based detection

Visual traffic / airborne hazard detection for the scan — airplanes, drones, and birds (as framed on /vtcas).

Visual on EFB / iPad

Traffic relative to the visual horizon so you can look outside and find it.

Windshield suction mount

Designed for almost any airplane; portable GA form factor.

One system for visual + ADS-B–class — built to replace a Sentry/Stratus/GDL/Dual-class weather-brick receiver.

Two pieces. One compute box. Dual-camera ready.

Current form factor (manufacturing update, Aug 11, 2026): a small camera with 3-axis BLDC gimbal on the windscreen, plus a separate compute box on the dash or out of direct view. Dual-camera support planned/supported on one compute box.

  1. 01

    Mount the camera

    Suction-mount the camera + 3-axis BLDC gimbal on the windscreen.

  2. 02

    Place the compute box

    Separate compute box sits on the dash or out of direct view — not an all-in-one GoPro-sized unit.

  3. 03

    Connect your EFB

    See visual traffic and ADS-B–class data on your iPad / EFB, referenced to the horizon.

  4. 04

    Optional second camera

    Dual-camera native support planned/supported on a single compute box.

Form-factor note: Earlier blog posts described a single GoPro-sized all-in-one. That direction was later reversed. This preview follows the Aug 11, 2026 manufacturing update (two physical pieces).

V-TCAS + portable ADS-B in one system — replace the weather brick

Portable ADS-B receivers (Sentry-, Stratus-, GDL-, Dual-class) stop at cooperative traffic and weather. Sentinel replaces that class of box: the ADS-B–class job plus camera visual traffic in one windshield-mounted system.

Cooperative traffic

Portable ADS-B–class transponder / cooperative traffic in the same system.

Weather

ADS-B weather for situational awareness on your EFB — same unit.

AHRS

Attitude and heading reference from the portable receiver.

Cabin pressure

Cabin pressure sensing as part of the integrated portable package.

CO alerts

Carbon monoxide monitor and alerts from the same portable unit.

Built for see-and-avoid — not to override it

Use Sentinel to support the visual scan: see traffic in context on the EFB, and keep cooperative traffic and weather in the same portable unit. It supplements outside-the-window flying. It is not a TCAS resolution-advisory system, and it does not claim to see all traffic.

Price context (from /sentinel comparison)

Published list prices only — not a feature-by-feature claim beyond what’s listed. Live /sentinel also notes V-TCAS, Retina touch display, dashcam recording, ADS-B benefits, CO monitor, pressure sensor, small & portable.
