Low-Altitude Cueing System
Finally, a use for "6 inches" that's actually accurate.
Ground Cue sends Bluetooth altitude alerts to your headset or audio panel, giving you big-airplane-style callouts with a tighter, more precise low-altitude ladder. Pair it once on your phone, then fly without needing the phone again.
- Bluetooth audio alerts to your headset or audio panel
- Granular callouts: 40, 30, 20, 10, 5, 4, 3, 2, 1
- Set up pairing once on your phone, then put the phone away
- Water vs. land callout mode for seaplanes coming soon
- Permanent-mount, no-battery version for experimental aircraft in the works
Based on a 6000 mAh battery pack with normal sensor and Bluetooth operation.
Send altitude callouts straight to your headset or audio panel.
Surface-callout development is aimed at shoreline and amphibious operations.
Why Ground Cue
Made for the last few feet, when "close enough" stops being good enough.
The idea behind Ground Cue is simple: low-altitude awareness should feel sharp, quiet, and immediate. No dense avionics menus. No generic industrial box. No guessing whether the system is talking to you or just talking. The callout ladder is tuned for the part that matters most: 40, 30, 20, 10, 5, 4, 3, 2, 1.
Clear cues, not cockpit clutter
The system centers on what matters fast: precise callouts in your ears, clean status, and setup controls you can actually reach in the field.
Built as a product, not just a project
The brand, UI, and hardware story are designed together so the system feels like something you buy with intent, not something you tolerate because it works.
Research path for surface awareness
Ground Cue is being shaped around real-world data collection for shoreline, land, and water cues, in addition to feedback from seaplane pilots.
The System
One compact sensor core. One cockpit-ready interface. One job.
Ground Cue pairs a dedicated low-altitude sensing core with Bluetooth audio output and a simple setup flow. Use the phone to pair and configure it, then let the system handle the alerts in flight without needing the phone again.
Altitude cueing
Big-airplane-style altitude alerts with a more granular ladder: 40, 30, 20, 10, 5, 4, 3, 2, 1.
Pair once, then fly
Use your phone to pair and configure the system once, then stop touching the phone.
Bluetooth audio output
Pipe the alerts into your headset or audio panel where they belong.
Surface mode in development
Water vs. land callout logic for seaplanes is in active development now.

Installed View
Real install photos, not just a bench-top prototype.
These shots show Ground Cue mounted on the aircraft, where the low-altitude sensing hardware actually lives. The goal is simple: compact packaging, clear line of sight, and an install that looks intentional instead of improvised.
Setup Flow
Simple enough to install, sharp enough to remember.
Mount the system
Set the sensor where it has a clean view.
Pair it once
Use your phone for the initial setup, pairing, and confirmation.
Fly with the cue
After setup, Ground Cue sends the altitude alerts without needing the phone again.
Coming Soon
Water vs. land callout for seaplanes.
Ground Cue surface mode is being developed for amphibious aircraft pilots who need to know what they're landing on and whether the gear matches the surface. Water or runway, gear up or down — the right call before the last few feet.
Pre-Orders
Join the first production wave. No money down.
Place a no-obligation pre-order to get first access when Ground Cue opens. No deposit is required now. You are just claiming a spot for updates, product details, and first notification when units are ready.
Ground Cue is presented here as a situational-awareness aid. It is not a certified primary flight instrument and does not replace approved equipment, checklists, or pilot judgment.
